First Store in Nakano! Sushi Choushimaru Grand Opens New Urban-Style Location at 'Park City Nakano' Today, May 29 (Fri)

Choushimaru Co., Ltd. (Headquarters: Chiba City, Chiba Prefecture; President: Ken Ishii), which operates the gourmet conveyor-belt sushi chain 'Sushi Choushimaru,' grand opened 'Sushi Choushimaru Park City Nakano' on the second floor of 'Park City Nakano,' a new complex born at the JR Nakano Station North Exit, on May 29, 2026 (Fri).

Background and Positioning as an Urban-Style Store Since its founding, 'Sushi Choushimaru' has been loved primarily in suburban roadside locations. Following the opening of the Shinjuku Subnade store this February, the company is further promoting the development of urban-style stores. 'Park City Nakano,' where this new store is located, is a new landmark in front of Nakano Station, consisting of offices, residences, and commercial zones. As our first store in the Nakano area, we aimed to create a space that caters to diverse urban lifestyles, from lunchtimes for office workers to relaxing meals for nearby residents.

Unique Feature of the Park City Nakano Store: Enhanced 'Takeout Corner' Unlike our existing stores, this location features a 'Takeout Corner' near the register. Please feel free to stop by on your way home or after work. The convenience of being able to purchase items immediately without waiting is a key feature. You can easily enjoy Choushimaru's 'delicious stage' at home or in the office.

[Grand Opening Commemoration Part 1] Limited-Time 'Bluefin Tuna 5-Piece Set' on Sale! To commemorate our first store in the Nakano area and our grand opening, we are offering a special limited-time sale of our signature 'Bluefin Tuna 5-Piece Set' as the first part of our commemorative project. It is a luxurious plate worthy of a grand opening, allowing you to taste the deliciousness of various parts of carefully selected bluefin tuna, such as fatty tuna (otoro), medium fatty tuna (chutoro), and lean meat (akami), all at once. Please enjoy the sweetness of the high-quality fat and the rich umami unique to bluefin tuna together with our specially prepared vinegared rice.
