OUR STORY

It all begins
with the market's eye.

Our day starts at Toyosu market, before dawn.

As a Toyosu market wholesaler, NAGASHIRO Suisan works with genuine fish every day. The sourcing eye we honed at auction is the single root from which we run our own izakaya, sell seafood, and support fellow restaurants with marketing and operations — our four businesses.

BUSINESS 01 ｜ IZAKAYA

Seafood Izakaya “Kaketsuke Ippai”

Toyosu freshness from the first glass — our own seafood izakaya in Ueno.

海鮮居酒屋 かけつけ一杯 の店内

The day's best catch,
straight onto the menu.

Sourced each morning at Toyosu, so the menu changes with the sea. Bluefin tuna, uni, crab, oysters — from seasonal sashimi to charcoal-grilled plates. Take your time, with a cold drink in hand.
