Matsuya's Store-Limited 'Mirai no Lemon Sour' Gets Promoted to a Regular Drink

Matsuya’s store-limited ‘Mirai no Lemon Sour’ joined the regular drink menu, available at all stores without restriction, on October 20, 2026. The same day, it vanished from the official site’s store-limited menu listing — after roughly 85 days as a store-limited item, it has now switched over to a regular lineup product. The two varieties, ‘PLAIN’ and ‘ORIGINAL,’ each featuring a real lemon slice in the can, keep their price unchanged at 290 yen.

Alcoholic drinks like sours and beer are a rare sight on Matsuya’s menu, which centers on Beef Bowls and set meals, making the move from the store-limited lineup to the regular drink menu a notable shift.

Two cans join the regular menu, price still 290 yen

The two items that joined the regular drink menu are ‘Mirai no Lemon Sour ORIGINAL’ and ‘Mirai no Lemon Sour PLAIN,’ both priced at 290 yen. They’re now listed as regular drinks with no store restrictions. On the store-limited page, the rollout ran for about 85 days, from July 28, 2026 to October 20, 2026, during which the price (290 yen) and store count (430 stores) never changed — the product has carried over to the regular menu with the same specs intact.

The drink’s gimmick is that a real lemon slice floats up when the can is opened, and on July 31, the official X account posted a video showing exactly that. The launch announcement image carried the tagline “Why not pop it open?”, lining up the blue-themed ‘PLAIN’ can and yellow-themed ‘ORIGINAL’ can alongside Asahi’s ‘Super Dry Nama Jokki Can’ (290 yen) as the store-limited alcohol lineup.

During its store-limited run: 430 stores across 28 prefectures, over 40% in Tokyo alone

Right up until it moved to the regular menu, the store-limited rollout reached a maximum of 430 stores nationwide — about 35% of all 1,221 currently operating Matsuya stores. The distribution was heavily skewed: Tokyo’s 193 stores accounted for about 45% of the total, meaning nearly 60% of Tokyo’s 337 currently operating stores carried the drink.

Prefecture	Stores Carrying It
Tokyo	193
Kanagawa Prefecture	59
Osaka Prefecture	58
Saitama Prefecture	31
Chiba Prefecture	30
Hyogo Prefecture	11
Aichi Prefecture	8
Fukuoka Prefecture	8
Kyoto Prefecture	5
Miyagi Prefecture	4

Beyond these, a handful of stores each were scattered across a total of 28 prefectures. The greater Tokyo area (Tokyo, Kanagawa, Saitama, and Chiba) alone accounted for 313 stores, over 70% of the total, followed by the Kansai region (Osaka, Hyogo, and Kyoto). Meanwhile, 18 prefectures — Mie, Nara, Yamanashi, Gifu, Ishikawa, Toyama, Fukui, Yamaguchi, Shimane, Saga, Nagasaki, Oita, Kochi, Kagoshima, Okinawa, Aomori, Akita, and Fukushima — had no participating stores at all, despite having operating Matsuya locations. The rollout looked less like a true “store-limited” offering and more like a deployment concentrated in the greater Tokyo and Kinki areas; with this move to the regular menu, that regional imbalance now goes away.

From a roughly 10-month-later re-launch to the regular menu

This isn’t the first appearance of ‘Mirai no Lemon Sour.’ Looking back at past announcements, it first appeared at Matsuya on September 30, 2025. Back then, it was a regional offering centered on 452 Matsuya stores in “Tokyo and the three neighboring prefectures,” with the same two varieties — PLAIN and ORIGINAL — each priced at 290 yen.

In the re-launch roughly 10 months after its debut, in July 2026, the rollout expanded significantly — from the original region to 430 stores across 28 prefectures, now including some Matsunoya locations alongside Matsuya. The price stayed unchanged at 290 yen each from the first launch.

From a regional debut, to an expanded store-limited rollout spanning 28 prefectures and 430 stores including Matsunoya, and now to a regular drink menu item available without store restrictions — the drink has followed a path of building up through store-limited rollouts before settling into the regular lineup, all while keeping its 290 yen price consistent from day one.
