Matsuya's Official X Account Visits the 'Matsuya/Matsunoya Sayamadai Store,' Which Opened on September 30

Matsuya’s official X account (@matsuya_foods) announced in a post on October 4, 2026, that it had visited the “Matsuya/Matsunoya Sayamadai Store” in Saitama Prefecture, which opened on September 30. The post also included the answer to a store-guessing quiz it had posted that morning, and noted that there are four Matsuya stores with “Sayama” in their names within Sayama City.

Visiting the Sayamadai Store and Ordering an Umatoma-Style Hamburg Steak

The post opens with “Today I went to the newly opened (㊗️ congratulations!) ‘Matsuya/Matsunoya Sayamadai Store’ in Saitama Prefecture, which opened on September 30 (╹◡╹)”. As the name suggests, it is a combo store pairing Matsuya (beef bowls) with Matsunoya (tonkatsu), and the visit came exactly four days after opening.

The exterior is black-based with a yellow line trimming the eaves, and signs and logos for both Matsuya and Matsunoya are displayed. On both sides of the entrance are notices reading “Opening Commemorative Service Vouchers Being Distributed!”, and a celebratory flower stand stands beside it.

On the table are a hamburg steak topped with tomato sauce and a soft-boiled egg, rice, miso soup, a cabbage salad, and jasmine tea. The hamburg steak, with its tangy tomato-based sauce, falls into the Umatoma family, which is what this flavor means at Matsuya. The post is written in the account’s usual casual tone, with the ㊗️ emoji and the (╹◡╹) emoticon.

According to the opening notice visible in the foreground, the Sayamadai Store opened at 10:00 a.m. on Wednesday, September 30, 2026. It is located at 1-1-8 Sayamadai, Sayama City, Saitama Prefecture, and offers 22 parking spaces and a drive-through. Morning meals, served from 5:00 a.m. to 11:00 a.m., start at 350 yen, and rice refills on set meals are free. As an opening commemorative, free service vouchers (valid through the end of October 2026) are being distributed, redeemable for your choice of Potato Salad, Kimchi, Grated Radish with Green Onion, or 3 Pieces of Jelly.

This Morning’s Quiz Answer Is “Matsuya Sayamashi Ekimae Store”

The post ends with “Oh! The answer from earlier is ‘Matsuya Sayamashi Ekimae Store’!” This is the answer to the store-guessing quiz posted with an image that morning, asking “Which Matsuya is this? (╹◡╹)”. The correct answer was the Matsuya Sayamashi Ekimae Store, a different store from the Sayamadai Store that was visited.

The post also says, “I didn’t realize there were as many as four Matsuya stores with ‘Sayama’ in the name.” In Sayama City, Saitama Prefecture, besides the Sayamadai Store visited this time and the Sayamashi Ekimae Store from the quiz, there are the Matsuya Sayama Store and the Matsuya Sayama Negishi Store, making four Matsuya stores with “Sayama” in their names within the city. Although the store visited and the quiz answer are different stores, both are connected by the name “Sayama.”
