First Drop Co., Ltd. (headquartered in Yokohama, Kanagawa Prefecture; President Kentaro Hirao), which operates about 50 restaurants across the Yokohama and Tokyo area, is opening a new conveyor belt sushi restaurant, Kaiten-zushi Toyosu Maguro Ichiban, in the first-floor restaurant zone of LaLaport Shonan Hiratsuka on Saturday, August 8, 2026. The restaurant draws on the company's trading rights at Toyosu Market and Yokohama Central Market.
Kaiten-zushi Toyosu Maguro Ichiban takes part in the auctions at Toyosu Market, buying whole tuna weighing over 100 kilograms after assessing each fish's condition. Carrying forward the dedication to ingredients built up at Kaiten Toyama Sushi Ginza, the restaurant aims to be an authentic, family-friendly conveyor belt sushi spot that fits into the local community's everyday meals.
Kaiten-zushi Toyosu Maguro Ichiban's Biggest Strength: Direct-Buying Power
The restaurant's biggest strength lies in the purchasing power made possible by its trading rights at Toyosu Market and Yokohama Central Market. At Toyosu Market, where prime seafood arrives from across Japan and around the world, staff select and win fish and shellfish at auction with their own eyes, then bring it straight to the table.
The Name Says It All: Whole Tuna Over 100 kg, Bought Directly at Toyosu
The "maguro" (tuna) in the restaurant's name comes from its own staff taking part in the Toyosu Market auctions, judging each fish's condition and buying whole tuna weighing over 100 kilograms.
Because the tuna is bought whole, guests can enjoy everything from the classic akami, chutoro, and otoro cuts to rarer parts like kamatoro, sukimi, and skin ponzu gunkan, along with the differences in flavor between cuts, making full use of a single fish. True to the name "Kaiten-zushi Toyosu Maguro Ichiban," the restaurant puts tuna at the center of its conveyor belt sushi.
A Commitment to Ingredients Inherited from Kaiten Toyama Sushi Ginza
That foundation comes from the sushi-making the company has built up at Kaiten Toyama Sushi Ginza, valuing where and when each fish was caught and its freshness so guests can enjoy the fish's flavor at its best. Rather than keeping quality sushi behind a high threshold, the aim is to make authentic sushi made with reliable ingredients more accessible and easygoing to enjoy. Kaiten-zushi Toyosu Maguro Ichiban carries forward that Kaiten Toyama Sushi Ginza philosophy while evolving it into a conveyor belt sushi brand the whole family can enjoy together.
More Than Tuna: Seasonal Catch Selected from the Market
Tuna isn't the only draw. Using its trading rights at Toyosu Market and Yokohama Central Market, the restaurant also carefully selects seasonal fish that arrive at the markets from around Japan, actively incorporating local Kanagawa seafood as the seasons change, so guests can enjoy the kind of fun only a market offers: what fish is there today?
What Matters Most: Conveyor Belt Sushi the Whole Family Can Enjoy
Above all, what the restaurant values most is being conveyor belt sushi the whole family can enjoy.
For parents, there's authentic whole-bought tuna and seasonal fish straight from Toyosu Market; for children, the fun of picking their favorite plates and the excitement that only conveyor belt sushi brings. From young children to grandparents, the restaurant aims to be a place where everyone can freely enjoy what they like, somewhere three generations want to visit together. From a family meal on the weekend, to lunch during a shopping trip, a child's celebration, or dinner on a day when something a little special sounds good, the goal is to be there not just for special occasions but for the everyday moments when a family decides, "let's have sushi tonight."
