Zuke is one of the traditional Edo-style sushi methods. It is said that it was started in the Edo period to stop tuna from rotting when there were large amounts of the fish in the market. Now that there has been advances in refrigeration technology, it’s no longer necessary, but maturing the fish gives it a completely different taste and brings out its umami. Zuke is divided into two broad methods. Here we describe the characteristics of each.
Recently, most sushi restaurants incorporate the “Single Zuke”.
Each slice of tuna is soaked separately, so it can mature quickly. The immersion time is only a few minutes. The idea is to marinate just enough so that the tuna’s aroma remains and the soy sauce doesn’t overtake it.
On the other hand, the old Edo-style method is to perform Zuke after parboiling.
Parboiling means to wrap the fish in a wet cloth, and poor boiling water on the wrapping until the color of the tuna changes color, then turn the fish over and repeat the process. The fish is then put in ice water so the heat doesn’t go too deep in the meat. It is immediately removed once it cools so that it doesn’t get too watery. The tuna is then put in Zuke soy sauce and left to marinate for about half a day. In this method, the soy sauce only soaks into the surface part where the color changed from the parboiling, so the flavor of the tuna remains.
Both methods keep the maximum tuna flavor possible. Tuna is an essential part of Edo-style sushi. There is great diversity between sushi restaurants in the parts, marinating time and flavor of Zuke, which creates a new, original flavor when the lean meat of the tuna soaks up the soy sauce. The fattiest cuts of tuna are most popular. The lean meat has only become more popular due to a rekindled interest in zuke, but in fact during the peak of the bubble economy, there was a time when high-end restaurants in Ginza didn’t know what to do with all their leftover lean tuna meat. It’s almost unbelievable to think of it now.
Using too much soy sauce spoils delicious sushi so make sure to only put a bit of soy sauce in the special dish. Make sure to tilt the sushi to the side and put just a dab on the end of the topping. Gari can be used as a brush to apply soy sauce to sushi rolls since they cannot be tilted. However, there are differing opinions as to whether this is a refined way to eat or not. Many people say it was basically made up by a publishing company. You just need a few drops in the soy sauce cruet. Actually at very fancy establishments the sushi is served with Nikiri so normal soy sauce is never used for dipping.
It’s a well-known fact among professional chefs that some fish don’t rely solely on freshness. Of course there is importance in freshness, but that’s just one element. It’s generally understood that flavor and taste improve with time (maturity).
The umami* found in the meat of the fish is essentially inosinic acid and glutamic acid. After a certain amount of time has passed after a fish has died, the body stiffens and not long after that the rigor lets up. The inosinic acid, which the umami is composed of, comes after the fish has stiffened. It then accumulates in the process of the body relaxing. This is the same in beef and pork in which there is no umami in the meat unless it is hung and matured for a time.
Therefore, ikizukuri sashimi that is still twitching usually won’t have the taste or depth of umami. However, the firm texture of sashimi is also an undeniable enjoyable aspect. It is not all about the umami.
*Glutamic acid, Inosinic acid and Guanylic acid are representative components of umami. Guanylic acid is found in kelp and vegetables (tomato, Chinese cabbage, green tea, etc.) as well as Parmesan cheese, inosinic acid is found in fish (bonito, macheral, sea bream, etc.) and meat (pork, chicken, etc.) while Guanylic acid is abundant in mushrooms (especially dried shiitake mushrooms).
Fermented beverages such as sake and wine pair well with sushi. Sake is made from rice. So it only makes sense that this would pair well with sushi – also made with rice. It is also the only alcohol that eliminates the smell of fish and shellfish.
On the other hand, when considering compatibility with wine, toppings that use strong seasonings like Nikiri, including tuna and conger eel with sweet filling, match superbly with matured red wines such as Pinot Noir.
For example, Bourgogne Chambolle Musigny, Cote de Beaune, Morey-Saint-Denis, etc.
White wines such as a lighter Chardonnay, Sauvignon Blanc and Riesling go well with white fish flavored with Citrus sudachi and yuzu or squid eaten with salt.
For example, Bourgogne Chablis.
However, neither red nor white wine goes well with herring or salmon roe. The iron specific to wine is said to contribute to the fishy smell of fish roe.
In the research of one wine manufacturer, the factor that generates the smell of fish and shellfish is the iron (ferrous ion) found in wine. Wines with relatively low levels of iron such as Sherry (Spain), Champagne (France) fermented twice in the bottle, Cava (Spain) and Franciacorta (Italy) mature without adding sulfite, which prevents oxidization. This reduces the ferrous ion in the wine and the fishy smell is virtually unnoticeable.
Either way, the research of wine and sushi pairings is still insufficient and there haven’t yet been any reports of unexpected compatibility. If anyone out there has found a wine that does pair well with herring or salmon roe, please be sure to share that information with us.
Conveyor belt sushi restaurants and high-end sushi restaurants in areas like Ginza both serve sushi, but they differ significantly in their roles and the quality of the experience they offer.
The most obvious difference is the price range. Conveyor belt sushi offers dishes starting at 100 yen per plate, making it affordable and popular among families and students. In contrast, high-end sushi restaurants primarily offer “omakase” courses, which can cost between 10,000 and 50,000 yen per person. These establishments are often chosen for special occasions or business entertaining, where customers seek an extraordinary experience.
The serving style is also contrasting. At conveyor belt sushi restaurants, the self-service style where sushi is served on a conveyor belt is the norm. Recently, touch-panel ordering and high-speed conveyor beltshave been introduced to prioritize efficiency and speed. In contrast, high-end sushi restaurants primarily use a counter-style setup where chefs prepare each piece of sushi by hand and serve it directly to customers. Sushi is not merely a meal but an experience of “once-in-a-lifetime” interaction between the chef and the customer.
At the core of this “experience” lies the sushi chef’s observational skills and conversational abilities. Chefs at high-end sushi restaurants constantly observe customers’ eating progress, expressions, and how much they drink. They make split-second judgments about whether the sushi is being enjoyed, the timing for the next piece, and the customer’s hunger level, all while serving dishes at an impeccable pace. They do more than just serve sushi; they may also briefly explain the origin of the ingredients or the preparation process, or engage in conversation to lighten the mood. This ability to maintain the perfect balance—neither too much nor too little—while giving customers a sense of comfort and familiarity is a testament to the chef’s experience and human touch. Such interactions are a unique feature of high-end sushi restaurants that cannot be experienced at conveyor-belt sushi restaurants.
There are also significant differences in the toppings used and the depth of preparation. At conveyor belt sushi restaurants, cooking processes are streamlined to accommodate large volumes, and frozen or pre-processed ingredients are commonly used. Traditional Edomae-style techniques such as kobujime (kelp-wrapping), sujime (vinegar-marinating) are rarely seen, and the standard style involves placing ingredients on rice shaped by machines. This streamlining contributes to the appeal of enjoying sushi affordably and quickly.
In contrast, high-end sushi restaurants use fresh, natural ingredients sourced daily, with each ingredient prepared in the most suitable way. The sushi chefs carefully craft each piece to bring out the individual characteristics of the ingredients, and even the rice is meticulously prepared, with attention to the type of rice, vinegar, and temperature. The chefs adjust the size and firmness of each piece based on their judgment to achieve the perfect harmony between the ingredients and the rice.
Furthermore, there is a significant difference in the atmosphere of the restaurants themselves. At conveyor belt sushi restaurants, the layout prioritizes efficiency, with tables as the main seating arrangement. The interior design and furnishings are often cost-effective, creating a bright and casual atmosphere. In contrast, high-end sushi restaurants feature natural wood counters, carefully selected tableware, and soft lighting, with a consistent aesthetic throughout the space. Even the chairs, chopstick rests, and chopsticks are made from high-quality materials, all functioning as part of the stage setting for the art of sushi.
Even among high-end sushi restaurants, there is a wide range of styles. For example, some restaurants, like “Sukiyabashi Jiro,” serve only sushi, with no appetizers or side dishes, focusing solely on the sushi itself. Others offer a course that includes appetizers, grilled dishes, and simmered dishes before the sushi, allowing customers to enjoy the pairing with sake. Especially in the latter style, rare local sake and seasonal limited-edition sake from all over the country are available, and the entire course is presented as a story, taking into account the compatibility of the dishes with the sake.
On the other hand, conveyor belt sushi is basically designed as a place to enjoy sushi quickly and easily, with drinks centered around beer and standard sake. Appetizers and side dishes are not emphasized. In this way, even among high-end sushi restaurants, there are those that “compete solely on the quality of their sushi” In this way, conveyor belt sushi and high-end sushi restaurants have completely different philosophies and roles, from price, serving style, ingredients, and space to the relationship with the chefs. Conveyor belt sushi combines efficiency and fun, making sushi a more everyday part of Japanese cuisine. High-end sushi restaurants present sushi as an “art of cuisine,” blending technical skill and aesthetic sensibility to convey the depth of sushi and the essence of Japanese culture.
By understanding the unique appeal of each and choosing according to your purpose or mood, you can fully appreciate the multifaceted nature of sushi as a dish.
This ginger includes Zingerone, a pungent component, and Gingerol, a spice component that changes to Shogaol when heated. Zingerone and Shogaol combine with the components that cause the fishy smell of fish and can eliminate that smell from its source. It makes sense to use ginger as a condiment for fish known for a stronger smell, like horse mackerel and bonito. The Gari served with sushi utilizes the effects of these components effectively for the enjoyment of the delicious taste of the sushi.
On the other hand, wasabi works by numbing senses of taste and smell with a stimulating spice so that the consumer doesn’t experience the fishy smell.
Furthermore, when you try to eat a light sushi topping after one with a richer flavor, a bit of Gari will cleanse your palette so you can fully enjoy the lighter fish. The pungent component also accelerates saliva production, assists with digestion and enhances absorption.
In summary, ginger removes the fishy smell at the source, while wasabi prevents you from noticing the fishy smell.
How the fish is butchered also changes the taste. If the fish suffers and struggles, the body wears and may be damaged, circulating oxidized blood throughout the body, which makes it lose flavor. For fish of high value such as sea bream, flounder, yellowtail, rudderfish and tuna, a method called “ikejime” is used.
The taste of tuna is said to be determined based on the preparations after being caught. The tuna is caught with as little suffering as possible and the nerves are killed immediately for an instant death. Generally, blood is then drained perfectly, entrails and gills are removed, the tail cut off and then the fish is placed in ice-water to lower the body temperature.
The medulla oblongata and main artery of the fish are cut and a kitchen knife is inserted into the base of the tail to drain the blood. A thin metal rod is inserted into the backbone to paralyze the nerves and at the same time controls the putrefied materials that come out of the spinal cord.
This extends the time until rigor mortis sets in, making it easier to maintain freshness and simultaneously preventing blood from circulating in the body, which also prevents the fishy smell.
Freezing the fish to death in ice water is called “nojime”. This method is generally used for small fish such as sardines, horse mackerel and mackerel that are fished in large volume. Although the freshness of the fish deteriorates more quickly than in the case of “ikejime,” it can be done in large quantities without a lot of labor and maintains a certain level of freshness afterwards.
At fish markets, the term “kill” is not used for living fish, instead the word “shimeru” meaning to close or tighten. The term “dead fish” is also not used. Instead the term “nojime” is used for fish that died naturally en route to the market. This stems from the awe of precious life and turning that life into food.
Even if you order beer or sake at sushi restaurants, your meal will always end with a cup of tea. But if you’re going to go out for sushi, you should really start drinking that tea earlier instead of saving it until the end. The tea at sushi shops is far more significant than a simple beverage. Especially when eating fatty tuna or bonito, tea plays a role that beer and sake simply cannot fulfill.
The key is in its hot temperature.
Hot tea works to dissolve the fat left on the tongue. Traces of fat is left on your tongue when you eat fatty sushi. It covers the taste buds like a film, subtly inhibiting your sense of taste. It would be a shame to miss your chance to experience the full range of flavors on your visit to a delicious sushi restaurant. No matter how much you drink, beer and sake can’t do anything about this thin film.
But drinking hot tea dissolves the fat and washes it away. Tea can also be considered a type of preparation for enjoying the next piece of sushi.
Another fun fact, sushi teacups are bigger than traditional tea cups because sushi chefs used to man their food stands alone. They just didn’t have enough hands to be constantly refilling tea while also pressing the sushi. The stands used large teacups so they wouldn’t need to be refilled as often.
We are sure you’ve never heard of an interpreter accompanying you to a restaurant. Why does Sushi University go through the trouble of providing an interpreter? This is because sushi restaurants have an element that you won’t find at any other restaurant in the world. That is because they are the only restaurants where you can have a direct conversation with the chef. Sushi chefs make the sushi in front of the customers and in addition to chatting while the sushi is being made, they also make an effort to invite conversation that inspires thoughts of the changing seasons and make your experience memorable. Normally this isn’t an option for visitors who don’t speak Japanese, but our interpreter gives you this opportunity. This is one thing that makes Sushi University interesting and unique.
What to expect
The more you know about sushi, the better it tastes. Let’s consider the meaning of these words.
Fish and shellfish are worked with while they are still fresh and fixed into a state that they can be stored. This process was created for Edo-style sushi and has continued to be passed down for approximately 200 years.
These methods were normal practice during a time without refrigerators and the practices continue in almost the same way today. However, the purpose has shifted from optimum storage to optimum taste of each ingredient. In other words, sublimation for even more delicious sushi.
The techniques known as “work” on the sushi, including salting and soaking in vinegar, steaming and boiling and thorough pickling are commonly known in Edo-style sushi, but do you think about which work is applied to each individual topping when you eat it?
Just slicing up seafood and slapping it on some vinegar rice is not Edo-style sushi. It’s fresh. It has fat on it. You should think about the work put into the dish, not just whether the fish is sweet or fatty.
Sushi University offers plans that allow you to acquire basic knowledge of Edo-style sushi while you’re eating. After the lecture you’ll want to visit sushi restaurants even more than ever before.
Why us
Sushi University interpreters aren’t just translating the words. There are a lot of things that even regulars at sushi restaurants don’t know. This is because restaurant mentor is always watching over everyone and is in a position to answer questions honestly. The mentor normally doesn’t take the initiative to talk to people and it might just be the interpreter’s job to create opportunities for dialogue.
Our interpreters are able to do this because they are well-versed in Edo-style sushi and have a firm grasp of the basics of why each sushi dish is good and what work was done to make it so delicious. Interpreters who are not familiar with sushi get caught up in just the words of the interpreting and often don’t have the capacity to engage in meaningful exchange with the mentor. Not just anyone can become an interpreter.
What sushi restaurants does Sushi University visit?
This information isn’t disclosed until the day of the course. If students learn the name of the sushi restaurant in advance, they may search for it online and find mistaken information or acquire unnecessary preconceptions. The course is not about where you will eat the sushi, but why it is delicious and what Edo-style work has gone into the dishes to create that flavor. This is what you should focus on during your visit. Thank you for your understanding.
Can I talk to other Japanese customers?
In high-class sushi restaurants, it is understood that you are not allowed to talk to the person next to you. This is because some people use them for business entertainment. However, in sushi restaurants where sushi university is held, the Japanese person next to you may talk to you. And it may even happen that they offer you sake.
Why do we need to provide my mobile number?
When you apply online, mobile number is a required field. However, we will never call your phone. Perhaps you feel that means it’s not necessary.
When we need to contact you, we will first call the hotel. If we can’t get ahold of you there, we will send an email. If we don’t get a response to the email, then we will send a message to your phone.
If you happen to be staying in an Airbnb, we will send a message to your mobile phone once we arrive at your Airbnb to pick you up.
We appreciate your understanding.
Why do you call the hotel the day before my reservation?
The day before your Sushi University reservation, our interpreter will call your hotel.
The reason for this is not only to confirm your reservation with you but also because the sushi chef will be visiting the Toyosu market the next morning to purchase the ingredients he will use for your meal. Some of the toppings are prepared a few days before serving, but most will be purchased on the morning of the reservation.
Most sushi restaurants serve an Omakase course. The benefit of this for the customer is that you will be served the chef’s expert choice. The benefit to the sushi restaurant is that they can avoid stocking seafood in the counter display case without knowing if they will have an opportunity to serve it or not. In other words, they won’t purchase seafood ingredients that they don’t need.
In recent years, global warming has affected fishing hauls and seafood prices have gone up between 50% to 100% from just a few years ago, so over-purchasing is an important issue from the viewpoint of running sushi restaurants and SDGs.
There are also some cases in which travel schedules change. Sometimes trains or planes are suddenly canceled or don’t run on schedule. Such things are unavoidable, but by calling your hotel the day before, we can understand and mitigate the situation a bit better.
Therefore, we will try calling your hotel the day before your reservation. If the hotel indicates that you have not checked in and do not intend to, we will send you an email and possibly send a message to your phone as well.
We appreciate your understanding.
What is the difference between a famous sushi chef’s restaurant and a sushiuniversity?
A sushi university is a dining tour for tourists.
Generally, interpreters who accompany tours eat the same food as the customers. On the other hand, interpreters on a sushiuniversity tour do not eat sushi.
The number of seats at the sushi counter is limited, so it is unusual for an interpreter who does not eat sushi to sit there.
Some sushi restaurants have staff or sushi chefs who speak foreign languages, but they don’t have time to respond to questions, so the conversation doesn’t really get going.
Unless you’re a regular customer who knows the ropes, it’s unlikely that you’ll have a satisfying dining experience. In other words, at a restaurant run by a famous sushi chef, it’s just an experience of eating the sushi that’s served.
Sushiuniversity could be called a small-scale dinner theater.
What kind of people participate in sushiuniversity?
There are all kinds of travelers: honeymooners, people with children, people eating sushi for the first time, people who run restaurants, people who have come to Japan for the first time, heavy traveler, Anonymous restaurant inspectors, foodies, and sushi connoisseurs.
Can you provide interpreters for languages other than English?
In Tokyo there are very few interpreters for languages other than English. However, if you apply well in advance, we may be able to find an interpreter in your language of choice. In this case, an extra fee will be applied.
Can children participate in the program?
Sushi University courses are not overly formal, but participants need to stay in their seats for a period of time. Please consider this when making your reservation.
Do you have a menu that caters to vegetarian, vegan or halal dietary requirements?
Unfortunately, we don’t have any dishes for vegetarians, vegan or halal.
If only one of the participants is vegan, we will provide sushi made with cucumber, avocado, shiitake mushrooms and kanpyo (dried gourd shavings) for that person.
Is there a children’s menu available?
Unfortunately, the sushi roll dishes that children tend to enjoy such as Salmon and Avocado rolls and California rolls are not available on a traditional Edo style sushi menu. The sushi can be made smaller, and wasabi can be left out, but generally the menu will be the same as the adult course.
I’m not a foreign tourist. I am a sushi chef. Can I participate in Sushi University?
Of course you can. Please ask any questions you would like, such as points to watch out for when making sushi, preparation methods, etc. We will answer what we can as sincerely as possible. However, you will not be able to actually cut toppings or make sushi in this course.
I am a foreigner living in Tokyo. Can I participate in Sushi University?
Of course you can. However, we will designate a hotel lobby for the meeting place. We are unable to make arrangements to meet you at your home or another place of your choosing.
Is it OK to take photos during the lecture?
It is OK to take photos of anything you are interested in, such as sushi ingredients and knife skills. A sushi master has given us permission. Please be careful not to accidentally get a picture of any other customers. However, please refrain from taking video and uploading to sites like YouTube.
Can I book a large party online?
Online reservations can be made for up to seven guests. For a party of 8 or more people, or anyone who is interested in reserving an entire restaurant, please email services@sushiuniversity.jp with the name of the course, the date, the number of people, your name and etc.

Back before there were refrigerators, wasabi was indispensable for Nigirizushi, eliminating the fishy smell and also providing bactericidal effects to prevent the fish from spoiling. Wasabi is originally from Japan and it has been used in Edomae sushi from the very beginning. Even with all the advancements in technology for storing sushi toppings, wasabi is still used today to remove the fishy smell and prevent spoiling. However, nowadays the flavor and aroma of wasabi and the way it brings out the flavor of the sushi topping is the main focus.
When wasabi is grated and exposed to the air, its unique heat is made enhanced by enzymes. Using a coarse grater gives the wasabi a rough, fibrous texture that spreads the spicy flavor through to the back of the throat. On the other hand, if Sharkskin wasabi is grated finely, it foams up with tiny bubbles and makes a creamy taste. The type of wasabi depends on the personality of the shop.
However, the powdered wasabi and wasabi paste you find at kaiten-zushi (conveyor belt sushi) is primarily made from horseradish and is colored and scented with additives. It isn’t dried wasabi and it is significantly cheaper.
Sushi restaurants that advertise “Edo style” on the sign somewhat fear customers who order Anago (conger eel) right off the bat. If the customer then eats as if they are really taking the time to taste the sushi, then any chef not fully confident in their skills will want to hide under the sushi counter.
Anago is a topping that really demonstrate a chef’s skills (or lack thereof).
Edo-style sushi chefs work on many toppings. Anago is a perfect example of these toppings. It is actually first steamed to remove the fat. However, it’s a difficult balance to remove the fat while still leaving the umami. The steamed Anago is then boiled and flavored. Since the fish is plain, the flavoring is also a subtle skill and not an easy task.
Depending on the shop, the chef may make the sushi with the boiled fish, use Nitsume (boiling down) to bring out the flavor or lightly roast the fish before combining it with the rice. The chef’s ideas and abilities are apparent in the final dish. If the sushi is made from the freshly boiled fish, it should be soft and melt in your mouth…if the chef knows what they are doing! Lightly roasted Anago will have an aroma that fills your entire mouth.
The work this topping takes to serve is a chance for sushi shops to show off their specialties, but it is also a clear indicator of the quality of the shop. The level of the chef and quality of the sushi shop will be revealed as soon as you place Anago in your mouth.
According to most sushi masters, salt is the defining factor in the taste of gizzard shad (kohada).
Before seasoning gizzard shad with vinegar, the process starts with salting the spread open shad. It is the length the fish is salted that makes or breaks the fish. The reason for salting the gizzard shad is not just for flavoring, but also to draw out the umami of the fish. Salting for too long results in a briny taste; too short and the umami won’t come to the fore. The timing must be perfect in order to achieve that emotional “umami” moment.
This timing can be compared to boiling eggs: 3 minutes gets you soft-boiled eggs but five minutes gets you hard-boiled eggs. With eggs you can follow this rule of thumb, but no such rule exists for the spotted shad. The conditions for the salting time differ depending on the temperature, humidity, size of the fish and the degree of fat.
For example, a more slender fish in the middle of summer may be salted for 30 minutes, but a fatty fish in the winter needs to be salted for four hours. Just a few minutes longer or shorter than the perfect salting time completely changes the taste of the final dish.
Skilled chefs adjust the time on a daily basis according to the weather and the quality of the fish. Shops that can provide precisely the same spotted shad taste every day of the year are truly the best of the best.
The sushi restaurant is unusual in that the customer sitting at the counter can see the seafood (neta) from which individual servings will be made, and can watch the chef deftly perform his art while enjoying lively conversation. Sushi restaurants also differ from other restaurants when it comes to menus.
Typically there aren’t any.
If the customer is inclined to worry about what the bill will come to, he orders Okimari (combination set)*. This consists of 7 to 10 pieces of nigiri-sushi and nori-maki selected by the proprietor in such a way as to allow them to offer an affordable price. It is cheaper because, like ready-made clothes, Okimari is not necessarily made piece by piece to fill individual orders. Of course, it will not be of inferior quality. Okimari is prepared by the chef and his assistants in the same way that everything else the shop is prepared. If the diner still wants more, they are always free to order sushi of their choice (Okonomi). Generally Japanese customers eat no more than 10 pieces of nigiri-sushi.
People at the counter most often order Okonomi (a la carte)**, which may be likened to having suits tailor-made from the finest fabrics. The customer who orders only the best will find that the check at the end can get a little expensive. But this is worth remembering (sushi worth eating is never inexpensive).
Long ago people used to say that first ordering Okimari and then ordering Okonomi after was the best deal for eating sushi, but that is a thing of the past. Actually, there are more and more shops that don’t allow Okonomi orders. The only choice is Omakase***. In some cases, all customers sitting at the counter take their seats at the same time and eat the same dishes and the same sushi in the same order. Even if you know nothing about sushi toppings, if you leave it to a master sushi chef, they will provide you with a combination boasting a good balance of early, peak and late season sushi. Omakase is great as it allows you to concentrate on genuinely enjoying the sushi and, especially if you’re visiting a shop for the first time, there will be no confusion regarding the best dishes.
*Okimari－The price and menu content are easily understood when ordering “Okimari”. The rank of “Tokujou”, “Jou”, “Nami” are often used. Order additional sushi as you like for a more fulfilling experience.
**Okonomi－A way customers choose and order sushi they want to eat. If you clearly know what you like and want to enjoy eating at your own pace, ordering “Okonomi” your choice of sushi, would be best.
***Omakase－If you don’t have any preferences, and you are happy to have a professional choose the most delicious toppings from that day’s catch, then ask for Omakase.
The real way of making sushi rice for Nigiri sushi by a sushi master. There are 4 tips!
In order to bring sushi to life, it is extremely important how sushi rice (shari or vinegared rice) is made. Let me introduce a cooking method, a top grade sushi master uses.
First, wash the rice gently. Leave it to soak for about half an hour and let it fully absorb water. The most important point here is to keep the water level which includes the rice consistent (The first tip).
The rice should be cooked with water with a ratio of 10 to 9. A little less water than the regular rice, so that it is cooked slightly hard. This is the second tip.
While you wait for the rice to cook, make awasezu* by adding salt and sugar in vinegar. Also, set up hangiri (rice-cooling tub) for mixing the rice. Don’t forget to wipe the inside with a wet kitchen towel to prevent the rice from sticking to it.
Once the rice has finished cooking, leave it to steam for about 15 minutes and dump it out into hangiri. Pour awasezu immediately and let it sit for 30 seconds or so. Because the rice absorbs vinegar only while it is hot, managing this process quickly is the third tip.
After letting it sit for 30 seconds, spread the rice out with shamoji (rice spatula) as if cutting it down. Make sure that vinegar goes around using a cutting motion vertically. Additionally, fan the rice using a uchiwa (fan) to remove the moisture of vinegar and mix the rice with a cutting motion horizontally this time. Fanning with uchiwa is not to cool down the rice (Do not put the rice in the fridge to cool it down.), but to dry up the excess moisture of vinegar. Moving both hands as you consider it is the fourth tip.
After the rice is vinegared evenly, assemble it in one place and cover it with a damp kitchen towel. In about an hour, it is ready when sushi rice is settled. (Body temperature) Even in a hurry, if you don’t give at least 30 minutes, it won’t help the taste of course, and also won’t make it easy to form the rice for sushi. If you rush at the end, all the delicate attention up to this will be in vain.
*A professional recipe for awasezu is as follows. This is a recipe for short grain rice
species such as Koshihikari and Sasanishiki. Slightly sticky rice like calrose is not suitable for sushi rice.
(Ingredients)
Rice：360cc
Water：330 – 340cc
Komezu (Rice vineger)：50 – 60cc
Salt：1 tsp – 2 tsp
Sugar：1 tbsp plus 1 tsp – 2 tbsp plus 2 tsp
＊If you use Akazu (Red vinegar made from fermented sake lees), add almost no sugar.
The Japanese were not in the habit of eating salmon raw. Salmon was not a traditional topping in Edo-style sushi. The reason for this is that the existence of parasites has been well-known since long ago and there was no way to prepare the salmon raw.
According to the Ministry of Health, Labour and Welfare, salmon must be frozen at -20℃ for at least 24 hours in order to completely kill all parasites. Salmon served at sushi restaurants must be stored frozen and then thawed before serving.
The type of salmon (sake) you find in Japan is Chum salmon. However, most of the salmon served raw at sushi restaurants is Atlantic salmon. This is a popular topping throughout the world due to the high-fat content and smooth texture achieved by sea farming in places like Norway and Chile. The fish are strictly managed from water quality to the effects on the environment, so there are very few issues with parasites and the salmon can be eaten raw. However, the fact remains that the fish are administered a number of chemicals due to concern of the spread of disease-causing germs in the farms.
Even when salmon roe and sea urchin first started to be used as toppings, most sushi chefs said that these didn’t count as Nigirizushi and refused to use them. However the favorable reputation of sea urchin sushi in Ginza won out, it started to be used by more chefs and eventually became one of the major dishes.
The fifth-generation sushi chef at one long-standing shop says, “If it’s what the customers want, then salmon may also be rolled as Nigirizushi in the near future.” It may even become part of the standard menu.
At a pre-Edo sushi shop that features Hokkaido toppings, they are actually serving ultra-high grade salmon such as Keiji* and Tokishirazu**.
*Keiji are young salmon with immature ovaries or testes. Only 1-2 Keiji are found in a normal catch of 10,000 salmon. Normal salmon fat content is 2-15% but the Keiji has a very high body fat percentage at 20-30%.
**Tokishirazu are salmon swimming upstream at the beginning of summer. They are the same chum salmon found in the fall, but since they aren’t caught during the spawning season, the fish don’t have eggs or milt, and instead have a high-fat content. The name “Tokishirazu” stems from the fact that these fish are caught out of season, in summer and the name means ”ignorant of time”
Zuke is one of the traditional Edo-style sushi methods. It is said that it was started in the Edo period to stop tuna from rotting when there were large amounts of the fish in the market. Now that there has been advances in refrigeration technology, it’s no longer necessary, but maturing the fish gives it a completely different taste and brings out its umami. Zuke is divided into two broad methods. Here we describe the characteristics of each.
Fermented beverages such as sake and wine pair well with sushi. Sake is made from rice. So it only makes sense that this would pair well with sushi – also made with rice. It is also the only alcohol that eliminates the smell of fish and shellfish.
However, neither red nor white wine goes well with herring or salmon roe. The iron specific to wine is said to contribute to the fishy smell of fish roe.
Conveyor belt sushi restaurants and high-end sushi restaurants in areas like Ginza both serve sushi, but they differ significantly in their roles and the quality of the experience they offer.
Gari is pickled ginger.
On the other hand, 
How the fish is butchered also changes the taste. If the fish suffers and struggles, the body wears and may be damaged, circulating oxidized blood throughout the body, which makes it lose flavor. For fish of high value such as sea bream, flounder, yellowtail, rudderfish and tuna, a method called “
Freezing the fish to death in ice water is called “
Even if you order beer or sake at sushi restaurants, your meal will always end with a cup of tea. But if you’re going to go out for sushi, you should really start drinking that tea earlier instead of saving it until the end. The tea at sushi shops is far more significant than a simple beverage. Especially when eating fatty tuna or bonito, tea plays a role that beer and sake simply cannot fulfill.
Sushi restaurants that advertise “Edo style” on the sign somewhat fear customers who order Anago (conger eel) right off the bat. If the customer then eats as if they are really taking the time to taste the sushi, then any chef not fully confident in their skills will want to hide under the sushi counter.
According to most sushi masters, salt is the defining factor in the taste of 
For example, a more slender fish in the middle of summer may be salted for 30 minutes, but a fatty fish in the winter needs to be salted for four hours. Just a few minutes longer or shorter than the perfect salting time completely changes the taste of the final dish.
The sushi restaurant is unusual in that the customer sitting at the counter can see the seafood (neta) from which individual servings will be made, and can watch the chef deftly perform his art while enjoying lively conversation. Sushi restaurants also differ from other restaurants when it comes to menus.
If the customer is inclined to worry about what the bill will come to, he orders 
People at the counter most often order 
The Japanese were not in the habit of eating salmon raw. Salmon was not a traditional topping in Edo-style sushi. The reason for this is that the existence of parasites has been well-known since long ago and there was no way to prepare the salmon raw.
