Sushi Kazumasa is a reservation-only Edomae sushi counter where each piece reflects the turning of the season.

Fish arrives daily from Toyosu Market and other regions across Japan, and is prepared with careful handling — ikejime and nerve-cutting — with the chef judging the exact condition of each fish. Temperature, humidity and ageing are controlled in detail to draw out the fullest natural umami. Tuna comes from Yamayuki, one of Tokyo's most respected wholesalers, and is served alongside seasonal delicacies, sashimi and grilled dishes so that each visit reflects the very best of that particular day.

Two kinds of sushi rice are prepared and chosen piece by piece: a red shari made with five-year-aged red vinegar, giving depth and a long finish, and a white shari blending two rice vinegars for a cleaner profile. It is this switching between them that gives the counter its range.

Drinks run from sake to whisky — Yamazaki, Ichiro's Malt — and natural wine. Pairings selected by the chef are available, offering a different way to enjoy each piece.

The room is quiet and contemporary, wood and monotone in balance. Alongside the main counter there is a private raised room and a bookable private counter, with access via a rear entrance for guests who prefer discretion.

Dishes are served on Arita ware, and sake cups are Edo Kiriko cut glass — beauty that is looked at as well as tasted. Every detail, from a single piece of sushi to the room itself, is built to make an important occasion richer.
