‘Sushimatsu’s First Self-Service All-You-Can-Drink’ Emerges as a New Format Axis

Sushimatsu’s official account explicitly stating in this post that ‘Mitaka Minamiguchi Store is Sushimatsu’s first store to introduce 【self-service all-you-can-drink】’ marks a new axis in how the Sushimatsu brand operates its stores. Until now, drinks at Sushimatsu locations were mainly ordered individually, but Mitaka Minamiguchi Store has opened positioned as something of a flagship store, being the first within the Sushimatsu chain to introduce ‘self-service all-you-can-drink.’ Matsuya’s official X account has also shown interest, commenting ‘sounds super fun!’ and ‘might head over tonight…’ — a structure in which whoever runs the main brand’s (Matsuya’s) account is cheering on the new format experiment.

The Relationship Between ‘Mitaka,’ the Store’s Location, and Matsuya Foods’ Head Office

Sushimatsu’s official account explicitly describes the opening location in this post as ‘Mitaka, home to Matsuya Foods’ head office.’ Mitaka City is located in western Tokyo and is where Matsuya Foods’ head office is situated. Sushimatsu opening a store in Mitaka represents a new-format expansion into the area where Matsuya Foods’ head office is based, with the Sushimatsu store now standing alongside the cluster of Matsuya’s own stores in the Mitaka area, such as the Matsuya Main Store (Mitaka Main Store).

Opening Fair: ‘90 Yen Off the Three-Piece Bluefin Tuna Nigiri Platter’

As an opening-commemoration fair, an offer taking 90 yen off the ‘Three-Piece Bluefin Tuna Nigiri Platter’ is running from today, June 12, through Thursday, June 18. The three-piece platter format is a staple configuration for Sushimatsu’s bluefin tuna offerings, deployed here as a customer draw to celebrate the opening. The fair’s end date of June 18 falls one week after the opening, functioning as a device to boost foot traffic during opening week.

Today’s quote retweet, like the Matsuya PREMIUM Ginza Store opening-celebration quote retweet (6/10, 11:38 AM), pairs (╹◡╹) with the triple-ellipsis (‘…’), reproducing once again the appeal pattern of sister-brand opening celebrations combined with a musing-toned ‘might head over.’
