Matsuya Rolls Out 'Mirai no Lemon Sour' at 430 Store-Limited Locations

It has been learned that Matsuya’s official store-limited menu page newly listed a lemon sour drink, ‘Mirai no Lemon Sour.’ The listing went live at 10:00 AM on Tuesday, July 28, 2026, priced at 290 yen. It is eligible at 430 stores nationwide, an unusually large scale compared with every other store-limited menu item currently listed. The product had already been announced in an official notice dated July 23, 2026, as a July 28 release with limited quantities; this listing reflects the eligible-store list now appearing on the store-limited page as well.

The 430 Eligible Stores Are the Largest Store-Limited Rollout to Date

The store-limited page lists 430 eligible stores for this item. Among currently listed store-limited menu items, this is more than eight times the next-largest, ‘The Katsu Curry and Rice,’ which covers 51 stores. It also amounts to about 35.6% of Matsuya’s total store count (1,207, excluding stores under temporary suspension) — an exceptionally wide reach for a store-limited offering.

A lemon sour-branded drink appearing in Matsuya’s store-limited lineup is a new development; no earlier store-limited menu item has featured a lemon sour. Matsuya’s drink lineup already includes alcoholic options such as canned draft beer and bottled beer, but naming a specific drink as a store-limited item is unusual.

Concentrated in Greater Tokyo and Kansai, 18 Prefectures Excluded

Breaking down the 430 stores, eligible locations are found in only 28 prefectures, leaving the remaining 18 prefectures with no eligible stores at all. Tokyo alone accounts for 193 stores, or 44.9% of the total, and the top five prefectures — Tokyo, Kanagawa, Osaka, Saitama, and Chiba — together account for 371 stores (86.3% of the total). Even within the greater Tokyo area, coverage varies by prefecture: in Tokyo, 193 of the prefecture’s 336 stores (57.4%) are eligible, while in Saitama only 31 of 102 stores (30.4%) are eligible.

• Tokyo: 193 stores
• Kanagawa: 59 stores
• Osaka: 58 stores
• Saitama: 31 stores
• Chiba: 30 stores
• Hyogo: 11 stores
• Aichi: 8 stores
• Fukuoka: 8 stores
• Kyoto: 5 stores
• Miyagi: 4 stores
• Hiroshima, Iwate, Okayama, Ibaraki, Niigata: 2 stores each
• Hokkaido, Kumamoto, Tokushima, Tochigi, Shiga, Kagawa, Yamagata, Miyazaki, Wakayama, Shizuoka, Gunma, Nagano, Ehime: 1 store each

Of the 430 eligible stores, 303 are standalone Matsuya locations, 88 are combined with ‘Matsunoya,’ 34 are combined with ‘My Curry Shokudo,’ and 5 are multi-brand locations carrying both, meaning the item is offered across a wide range of store formats. Whether a nearby Matsuya is included can be checked against the eligible-store list on the store-limited page.

Two Can Varieties, Listing Went Live at 10:00 AM Tuesday

Menu Item	Number of Stores	Eligible Stores
Mirai no Lemon Sour	430 stores	Eligible Stores

The listed visual is built around the large headline ‘Wanna pop it open?,’ featuring two cans of ‘Mirai no Lemon Sour’ side by side — an ORIGINAL version and a PLAIN version. Each can shows an actual lemon slice inserted into the drinking opening, and both are labeled as a sparkling liqueur with 5% juice content and 5% alcohol by volume. The same visual also includes the ‘Asahi Super Dry Nama Jokki Can’ (290 yen) — a canned draft beer designed to produce a foamy head when opened — and both drinks are noted as ‘not available for takeout.’

The listing on the store-limited page went live at 10:00 AM on Tuesday, July 28, 2026. Matsuya’s store-limited menu items have consistently gone live at 10:00 AM on Tuesdays, and this release follows the same pattern. Note that the listing date on the store-limited page does not necessarily match the actual sales start date. The official notice announced the item as a July 28 release with limited quantities.
