Why is sushi with tuna topping so expensive?

A purchase of raw tuna costs at least JPY 30,000 per kilogram. Furthermore, good tuna is judged not only by taste, but appearance is also highly regarded.

The surface is gradually oxidized by letting it sleep (mature) and the sushi chef makes sure that parts are cut of as they change color, when the timing is perfect for both the taste and appearance. In other words, skin is taken from the freshly purchased tuna, the meat of the fish darkened by blood (the blackened area that can’t be used as sushi toppings) is removed, the parts that have changed color are shaved off and then only the remaining, best parts used as toppings are left.

This is why the price is high.

Prior to WWII, there were chefs whose only job was making vinegar rice!

From the end of the Edo period through the Meiji period, rice was cooked using firewood and a pot. It is not easy to get the fire at the right temperature and the rice has to be cooked to the same texture regardless of where it came from or the size of the grains, so at the time the task required a skilled chef. Therefore, there were “Shari-ya” employed by sushi restaurants who specialized in cooking rice. “Shari-ya” focused on this single task and were not involved in the actual making of the sushi after the rice was passed on to the chefs.
