Sushi Arai

Yuki Usui works the counter in the basement of a building in Ginza 8-chome. The room is below street level, quiet, and deliberately removed from the energy of the street above. The counter is straight Kiso hinoki — the same wood where Yuichiro Arai opened this restaurant and stood for six years, before the main room moved upstairs. The address of the original counter did not change. The man behind it did.

Usui trained at the Kyubey Okura branch before spending a decade alongside Arai. Kyubey is known for the demands it places on apprentices — speed, consistency, the ability to work at a high tempo without losing accuracy. Both qualities are visible at this counter.
Nigiri is constructed quickly and placed in front of you without adjustment or ceremony. The pace does not feel rushed. It feels like someone who stopped needing to think about the mechanics a long time ago.

The shari is the first thing that registers. The red vinegar blend is sharp and salt-forward, the rice cooked firm enough that individual grains hold their shape through the bite. Against o-toro, it cuts through the fat cleanly rather than sitting alongside it. The temperature of the rice shifts slightly depending on the cut — warmer for leaner fish, cooler for richer ones. This kind of adjustment rarely announces itself during the meal. It shows up afterward, in the absence of any single piece feeling out of balance.

Bluefin tuna comes from Yamayuki at Toyosu. Usui cuts it thick, which lets the assertive shari keep the richness in proportion rather than being overwhelmed by it. The Edomae preparation runs alongside the tuna throughout the meal — kohada cured with the precision that Kyubey training tends to produce, anago braised until it holds together without resistance, and the ohagi near the end of the nigiri sequence: minced toro combined with takuan, Arai's own recipe, made in the room where Arai's cooking began.

The room holds a handful of seats below street level — the quiet is part of the design. Dinner runs about ¥10,000 less than the room upstairs. The fish is the same.
