At first glance, this might seem like a minor difference in etiquette, but it actually reflects Japanese food culture and the chefs’ careful attention to flavor. This can be explained from two perspectives: taste and culture.
First, let’s look at the taste aspect, which explains how wasabi enhances the flavor of sushi.
When eating nigiri sushi (edomae sushi) at a sushi restaurant, wasabi is not served separately. Instead, the chef incorporates the optimal amount into each piece, carefully matching it to the type of fish and its fat content. Wasabi’s aromatic compound, isothiocyanate, is released the moment it’s grated and quickly evaporates when exposed to air. Mixing it into soy sauce causes both its fragrance and spiciness to be lost. Therefore, mixing wasabi into soy sauce is unnecessary; savoring it as the chef intended, with its carefully calculated balance, is considered the most delicious way to eat it. That fleeting moment when the refreshing aroma rises, blending with the umami of the fish and the acidity of the vinegared rice, is the true essence of sushi.
On the other hand, for sashimi, the correct way to eat it is to place a small amount of wasabi directly on top of the sashimi and dip the underside into soy sauce. This allows the wasabi’s aroma to spread across the fish’s surface, while the saltiness and umami components of the soy sauce are added subtly, enhancing the ingredient’s flavor most effectively. Mixing wasabi into the soy sauce destroys this delicate way the aroma unfolds.
Another reason comes from culture: appreciating how the chef intends each piece to be eaten.
In Edomae sushi, the “amount of wasabi” is also part of the chef’s skill. They calculate the optimal flavor balance by adjusting the intensity of the spiciness based on the type of fish and its fat content.
Mixing it into the soy sauce would disrupt the flavor harmony intended by the artisan. This is akin to someone arbitrarily adding salt or pepper to a sauce finished by the chef in French cuisine. In French cuisine, the flavor perfected by the chef on the plate is considered the final form, and guests respect that.
Similarly with sushi, appreciating the flavor balance designed by the chef for each piece is the ultimate courtesy and the best way to fully enjoy its flavor.
Now you know why you shouldn’t mix wasabi into soy sauce and the cultural reasoning behind it. Understanding both the taste and the tradition allows you to appreciate the chef’s skill—and earn their respect.
“Kaiseki” is one of Japan’s representative traditional course meals. Each dish is meticulously prepared, using seasonal ingredients and presented with beautiful plating.
In fact, there are two types of “Kaiseki”. One is “懐石料理”, the other is “会席料理”. Although both share the same pronunciation in Japanese, their purpose and atmosphere are entirely different.
Kaiseki cuisine (懐石料理) is a quiet, refined cuisine that developed as part of the tea ceremony. It is a light meal served to entertain guests, featuring subtle flavors. It values the natural flavors and seasonal beauty of ingredients.
On the other hand, Kaiseki cuisine (会席料理) is a lavish course meal served at banquets and celebrations. It features many dishes served in sequence, designed to be enjoyed for their visual beauty and festive atmosphere.
Both types of Kaiseki embody the Japanese spirit of hospitality and an aesthetic appreciation for the seasons. Experiencing Kaiseki is not merely eating a meal; it is experiencing Japanese culture itself.
Historical Background
Kaiseki cuisine (懐石料理) and Kaiseki cuisine (会席料理) both originated from the spirit of hospitality, but their purposes and histories differ.
Kaiseki cuisine (懐石料理) – Cuisine born from the tea ceremony
Kaiseki cuisine (懐石料理) was refined and popularized in the 16th century by the tea master Sen no Rikyū (千利休). It is a light meal served before a tea ceremony to warm the body and settle the mind. The term “Kaiseki” originates from the idea of “holding a warm stone against one’s stomach to ease hunger.” The cuisine is simple, conveying quiet beauty through the natural flavor of the ingredients, the arrangement of each dish, and the harmony among the tableware.
Kaiseki cuisine (会席料理) – Cuisine developed from banquet culture
In contrast, Kaiseki cuisine (会席料理) developed from the banquet culture of samurai and aristocrats. It is a style designed for enjoying food and savoring sake at celebratory gatherings. It is more elaborate than Kaiseki cuisine (懐石料理), featuring a greater number of dishes and a more luxurious appearance. It can be described as “social cuisine” that fosters social interaction.
Differences in Structure and Seasoning
Purpose of Serving
Kaiseki cuisine (懐石料理) is a meal served before a tea ceremony to prepare the mind. Kaiseki cuisine (会席料理) is a meal enjoyed with others at banquets or celebratory occasions.
Course Structure
Kaiseki cuisine (懐石料理) is fundamentally based on “one soup, three dishes” (一汁三菜). It typically consists of rice, soup, and three side dishes. In a typical Cha-Kaiseki (Tea Ceremony Kaiseki) menu, dishes are served in a precise and ceremonial order — beginning with oshiki (折敷), followed by wanmono (椀盛), grilled dishes (yakimono), simmered or vinegared dishes (shiizakana / 強肴), suimono (clear soup / 吸い物), hassun (八寸), yutō and kōnomono (湯桶・香の物), and finally omogashi and koicha (主菓子・濃茶).
Kaiseki cuisine (会席料理) is a more elaborate style, featuring many dishes served in sequence from appetizers to dessert. Kaiseki Ryori (会席料理) is a course meal enjoyed in a banquet style. In a typical menu, dishes are served in a specific sequence — starting with appetizers (zensai), followed by clear soup (suimono), sashimi, grilled dishes (yakimono), simmered dishes (nimono), deep-fried dishes (agemono), steamed dishes (mushimono), and vinegared dishes (sunomono). The meal concludes with rice and red miso soup (tomewan), pickles (kou no mono), and seasonal fruits (mizugashi). Some restaurants also include an aperitif (shokuzen-shu) to begin the dining experience.
Seasoning
Kaiseki cuisine (懐石料理) features delicate, subtly seasoned dishes that highlight the natural flavors of the ingredients. Kaiseki cuisine (会席料理), on the other hand, features more diverse and vibrant flavors, incorporating grilled, fried, and simmered dishes.
Tableware and Presentation
Kaiseki cuisine (懐石料理) tableware emphasizes seasonal sensibility and understated beauty. By contrast, Kaiseki cuisine (会席料理) uses colorful and ornate tableware, creating a visually pleasing presentation.
Differences in Serving Style
Kaiseki cuisine (懐石料理) – A quiet, meticulous flow
Kaiseki cuisine (懐石料理) follows the ritual flow of the tea ceremony, with dishes served one at a time to each guest. The host observes the guest’s pace and serves each dish with care. The spirit of “consideration” and “harmony” is felt within the quiet, serene atmosphere.
Kaiseki cuisine (会席料理) – Lively and Festive
Kaiseki cuisine (会席料理) is served at banquets and celebrations, often with dishes presented simultaneously, creating a lively atmosphere. It is a bright, social dining style enjoyed with conversation and sake.
Where can you eat it?
Kaiseki cuisine (懐石料理) and Kaiseki cuisine (会席料理) are dishes meant to be savored in special places and experiences.
Kaiseki cuisine (懐石料理) can be enjoyed in tea houses where you can experience a traditional tea ceremony, or in quiet temple lodgings (shukubō). Through the care infused into each dish, you can experience Japan’s “beauty of stillness.”
Kaiseki cuisine (会席料理) is typically enjoyed at Onsen Ryokan (hot-spring inns) or traditional ryōtei restaurants. It features multi-course meals using seasonal ingredients, beautifully presented, making it perfect for celebratory occasions or special travel dining.
Both offer a precious opportunity to experience Japan’s “hospitality.” Whether you choose the quiet. Kaiseki cuisine (懐石料理) or the elegant Kaiseki cuisine (会席料理) – whichever you select, the spirit of Japan lives within it.
Modern Differences and Misconceptions
Overseas, the term “Kaiseki” is often introduced as “high-end Japanese cuisine” or “special course meals,” and the distinction between Kaiseki cuisine (懐石料理) and Kaiseki cuisine (会席料理) may not be widely known. This frequently leads to the misconception that “Kaiseki = luxurious Japanese food.”
The original Kaiseki represents the spirit of hospitality and harmony with nature. It’s important to appreciate not only the flavors and presentation, but also the Japanese sensibility expressed through the tableware, pacing, and quiet intervals between courses.
To dispel this misunderstanding, one should explain Kaiseki cuisine (懐石料理) as “a light meal before a tea ceremony” and Kaiseki cuisine (会席料理) as “a formal multi-course meal for celebrations,” conveying the underlying cultural differences. When savoring Kaiseki, pay attention to the ingredients, the presentation, and the expression of the season. Within that lies the richness of the Japanese spirit.
The Diverse World of Kaiseki and the Difficulty in Understanding It
Kaiseki cuisine (懐石料理) and Kaiseki cuisine (会席料理) are distinct culinary styles with different purposes and atmospheres, yet even among Japanese people, the distinction between them is often unclear.
Many people use the terms interchangeably, and even on menus at traditional restaurants and inns, the two terms are often used interchangeably.
Furthermore, the composition and seasoning of dishes differ between the Kansai and Kanto regions, and the philosophy and aesthetic of presentation also vary among schools like Kyoto cuisine, Edo cuisine, and shojin ryori (Buddhist vegetarian cuisine).
In other words, even when simply referred to as “Kaiseki,” its content varies greatly depending on region, tradition, and the chef’s philosophy.
As a result, it can be difficult for non-Japanese visitors to grasp the distinction between the two forms of Kaiseki.
In fact, many travelers refer to the course meals served at hot spring inns or high-end Japanese restaurants as “Kaiseki,” but whether these meals possess elements of Kaiseki (懐石) or follow the format of Kaiseki (会席) varies by establishment.
Yet, this very ambiguity is part of what makes Japanese cuisine so intriguing. Kaiseki is not a fixed mold but a “living culture” that evolves with the seasons, regions, and people involved. Both share a common spirit rooted in the “heart of hospitality” and “harmony with nature.”
When visiting Japan, experience the unique charm of Kaiseki cuisine—whether it’s the quiet, monastic setting of a temple lodging or the elegant atmosphere of a hot spring inn.
You’ll surely sense the profound depth of the Japanese spirit in each and every dish.
The weight of the sushi rice ball is determined the moment the sushi chef forms it.
Nigiri sushi sold at street stalls during the Edo period is said to have been roughly the size of a small rice ball today, weighing about 50 to 70 grams per piece. According to historical records such as Morisada Manko (守貞漫稿), eating just two or three pieces was considered a sufficient light meal. Eventually, complaints that the sushi was “too large and difficult to eat” led to it being halved in size and served two pieces at a time, though there are several theories about why this change occurred. This adjustment allowed diners to enjoy a greater variety of toppings in a single visit.
The weight ofshari and toppings is actually decided by each restaurant; there is no industry standard.
So how did this weight come to be? The answer lies in a unit of rice that has been deeply ingrained in Japanese life.
In Japan, the smallest unit for measuring rice is called ichigo (一合), which equals 150 grams (180 cc). This is also considered a standard portion for one meal, and household rice cookers often have markings based on multiples of this unit. Cooking an ichigo yields approximately 300 to 330 grams of cooked rice. While actual consumption varies depending on age and gender, the concept of “ichigo equals one meal” has been established for centuries. This unit has been passed down not only in households but also in sushi restaurants, where chefs use it to calculate the required cooking volume and determine how much rice to prepare at once.
This unit is also scalable: ten times ichigo equals ishou (一升). Until about 30 years ago, it was common for sushi restaurants to cook nishou (二升) of rice at a time, and commercial rice cookers sized for this purpose were available. Today, chefs typically cook rice according to the number of reservations, often calculating one serving as a little over ichigo.
Looking further back, during the post-war rationing period, there was a “commissioned processing system” where rationed rice could be brought to sushi shops for processing. Bringing ichigo of rice to a sushi shop would get you seven pieces of nigiri sushi and one nori roll, equivalent to about ten pieces of nigiri. Working backward from this system, it is estimated that the rice weight per piece in the post-war period was approximately 30 to 33 grams.
This weight served as a standard benchmark for some time after the war. Gradually, alongside changes in food culture, this standard also shifted. Responding to customer requests to enjoy more sushi toppings, the amount of rice per piece gradually decreased. By the late Showa period, it was around 20 grams. Today, in the Reiwa era, the mainstream is 10–15 grams per piece in central Tokyo sushi restaurants and 15–20 grams in regional areas.
Sushi chefs carefully consider the thickness of the fish, its fat content, and the temperature and humidity of the rice to achieve the “balance that tastes best in one bite.” In recent years, partly due to rising ingredient costs, there has been a trend toward reducing the rice even further. Some pieces now weigh less than 10 grams, though it is said that reducing them any more makes it difficult to discern subtle differences in flavor, especially in white fish.
The weight of the rice is not merely a matter of quantity; it represents the “art of the bite,” shaped by 200 years of Japanese food culture and aesthetic sensibility.
This title might seem like a uniquely Japanese question. However, in neighboring countries like Korea and China, flounder (karai) and halibut (hirame) are also commonly eaten, and efforts are being made to cultivate them.
In many other countries, however, these fish are not distinguished and are often lumped together as “flatfish.”
One reason is the broad range of species covered by the English term “flounder.” For instance, many species like flounder, plaice, halibut, lemon sole, common dab, Pacific Dover sole, and fluke are all grouped under “karei.” Even the names alone can be confusing.
The common method to distinguish hirame and karei is the rule that when placed belly-side down (the white side), the hirame faces left and the karei faces right. However, there are exceptions like Numagarei (Starry flounder).
Species in the Pleuronectidae family, whose eyes are on the right side, are known as “righteye flounders,” while those in families such as Paralichthyidae and Bothidae, with eyes on the left, are called “lefteye flounders.”
Similarities and Differences Between Karei and Hirame
Both karei and hirame belong to the order Pleuronectiformes and share very similar shapes and colors. They both have flat bodies, are asymmetrical, and possess the unique characteristic of having both eyes on one side of their body.
What is Karei?
The Illustration of Karei
Flounder encompasses a vast number of species with a wide distribution range. In Japanese coastal waters alone, approximately 40 species have been identified, including Magarei (Yellow striped flounder), Meitagarei (Ridged-eye flounder), Ishigarei (Stone flounder), and Makogarei (Marbled flounder). The species caught also vary by region.
As they are relatively inactive fish, their flesh is characterized as soft and rich in fat. They feed on small fish, ragworms, and small crustaceans, resulting in a small mouth shaped like a “pursed mouth.” Additionally, their eyes are located on the right side of their body.
While fresh specimens can be eaten as sashimi, they generally have a slight distinctive flavor. Therefore, they are typically enjoyed cooked through methods like simmering, frying, deep-frying, or drying.
What is Hirame?
The Illustration of Hirame
Compared to karei, hirame has fewer species and a narrower distribution, making it relatively rare. Its scientific name is Paralichthys olivaceus, and it is a premium fish found in the coastal waters of Japan and Korea.
Hirame has well-developed muscles for agile movement, resulting in firm flesh. It has a large mouth and sharp teeth for catching small fish and crustaceans, and its eyes are located on the left side of its body.
When eaten raw, it has a crisp, firm texture that turns tender and flaky when cooked. It’s known for its mild flavor and delicate umami. It is popular as a premium ingredient for sushi and sashimi, and in French cuisine, it is also used in main dishes like meunière.
Its peak season runs from late autumn to early spring, with the winter variety, “Kanbirame,” boasting particularly rich fat content and exceptional flavor.
Conclusion
While karei and hirame may look similar, they have distinct differences in taste, texture, and ecology. In Japan, summer Makogarei (Marbled flounder) and winter Bastard halibut (Hirame) are considered premium fish, highly prized in sushi restaurants and traditional Japanese restaurants. Understanding these differences enhances the enjoyment of dining at sushi establishments.
When sauce is about to drip, do you catch it by cupping your hand like a plate with the hand opposite your chopsticks? This is commonly called “Tezara (手皿: Te means hand and zara means plate).” It often appears on Japanese TV during meal scenes.
While it might seem elegant, it’s actually considered bad manners in Japanese dining etiquette, so it’s best to remember this. You should be especially careful during important occasions. The basic etiquette for Japanese cuisine is to hold the bowl or dish in your hand while eating, so the correct way is to use the sauce in a small side dish, not your hand.
However, there are times when small side dishes aren’t provided, like when eating out or at home. In those cases, the basic Japanese approach is to hold the bowl itself close to your mouth for dishes with sauce. Alternatively, you can use techniques like lightly cutting the sauce with the tips of your chopsticks before bringing it to your mouth to eat neatly without using your hands.
Why is using your hand as a plate considered bad manners? If sauce drips onto your hand and stains it, you’ll need to wipe your hands with an oshibori (wet towel), creating extra laundry. Oshibori are meant for wiping hands before eating. If they get stained with food sauce, they may require stain removal, causing trouble for the restaurant.
Furthermore, while it’s common, seeing someone use their palm as a plate and then bring the food to their mouth can feel somewhat unhygienic and vulgar, even if the person themselves doesn’t mind. Depending on the situation, it’s considered bad manners during a proper meal.
In Japan, holding bowls and small dishes is considered polite.
In Japanese dining culture, holding bowls and small dishes is considered polite. Proper etiquette dictates lifting bowls and soup bowls to your mouth, while flat or large dishes should not be lifted—specific manners exist for each type of vessel. Using a serving dish instead of tezara is rooted in these uniquely Japanese dining customs.
Of course, during casual meals at home or with friends, you might unconsciously use your hand as a plate. While it often isn’t a major issue in daily life, it’s especially important to refrain from doing so at formal occasions, kaiseki dinners, or when dining with seniors. Being mindful of etiquette according to the situation will make your dining manners appear more refined.
It’s a gesture that anyone can easily do, but it’s best to avoid it at formal occasions. It may even look as if you’re drawing attention to a spill, so using a side plate or small dish is always the better choice.
