Limited Edition Sando (限定サンド)

On 6 January 2026 FamilyMart opened a strawberry fair, and within a week it reported 3.24 million items sold. Seven days in, on 13 January, the chain added an ichigo & whip sando at 498 yen. Seven-Eleven had put out its own ichigo sando on 5 January, built with two creams, custard and a mascarpone cream, between slices of soft white shokupan. Pull one from the chiller and the crumb is cold and slightly tacky, the cream firm enough to hold a clean cut, and the first bite lands on the juice of the berry before the sweetness of the cream. That is gentei (限定), the limited run, in its most ordinary form: a case at the register that rotates with the calendar, and a shopper who knows that this one will be gone by spring.

Strawberry season in Japan runs from about December to March, and the sando is the vehicle the chains reach for first. Chilled, the format is forgiving. The berry sits in the middle of a whipped-cream wall so that every slice shows a red cross-section, and the shokupan, which has almost no crust to fight the cream, folds under the teeth. The failure modes are wet ones. A berry that has been cut ahead bleeds juice into the crumb until the bread goes grey and soggy, and a cream whipped too loose slides out when the sandwich is lifted. Some convenience-store strawberry sandos stay on shelves for much of the year, with makers using tricks to keep supply steady, which leaves the January and spring editions to stand out through named creams, a second filling, or a stated variety of berry.

Autumn belongs to the egg. McDonald's Japan put the first Tsukimi Burger on sale in 1991, a fried or poached egg set in a bun, named for tsukimi, the custom of viewing the harvest moon, with the yolk standing in for the moon. Sources vary on how the idea was reached; one account says a survey of ingredients people wanted in a hamburger put eggs first, and that autumn was chosen because egg supply is steady then. The sandwich comes back every September or October, and the chain has run series around it: a cheese version from 1998 to 2014 and again in 2016, a double in 2008. The yolk gives way under the top bun and runs warm onto the patty, and steam from a fresh bun carries the smell of the sauce. For the 35th anniversary in 2026, a lineup of eight limited items added a Hokkaido potato and pepper version, sold from 24 September at 570 yen.

Winter at McDonald's Japan is the Gracoro, short for gratin croquette. It arrived on the menu in 1993 as the gratin croquette burger, and the nickname became its official name in 2021. The patty is a croquette the size of a burger, filled with shrimp and macaroni in white sauce, shelled in panko, set on a buttered, steamed bun with shredded cabbage, mayonnaise, and croquette sauce. The shell crackles first and the inside is molten, hot enough to scald the palate on a hasty first bite, with the cabbage cold against it. A bolognese version appeared in 2021, and in 2023 a limited item combined demi-glace and cheese. Because it leaves the menu each spring and returns each winter, the burger has the pull of an annual date, and customers look for it the way others look for the first cold snap.

Regional editions tie the calendar to a place. Mos Burger's staff-idea campaign for local specialties reached its fourth round on 13 September 2018, with two burgers chosen from 2,651 applications, more than double the previous year's. A Hyogo team built the Kakogawa demi-gra beef cutlet burger, 410 yen, on the demi-glace beef cutlets of the city's katsumeshi. A Shizuoka team built the Suruga Bay sakura-ebi croquette burger, 430 yen, in which a creamy shrimp sauce sits with cabbage on the croquette. Both ran until mid-November. The sakura shrimp are landed at Yui and Oigawa ports and fished in two seasons a year, spring and autumn, which makes the ingredient itself a short-run item before the burger is assembled around it.

Origin and history

No company or cook is credited with inventing limited-edition sando; gentei is a retail habit, and its sandwiches arrive one product at a time. The earliest dated anchor in this set is autumn 1991, when McDonald's Japan introduced the Tsukimi Burger. The Gracoro followed in 1993 as a winter counterpart, and the two bracket the year the way the convenience-store strawberry runs bracket the cold months.

Of the chains in this set, McDonald's keeps the longest record. The Tsukimi Burger has returned every year since 1991, with new series layered on top: the cheese series of 1998 to 2014, the 2008 double, and the potato and pepper edition of 2026. The convenience stores work on shorter clocks, with a January strawberry launch and a spring follow-up such as Seven-Eleven's, which began rolling out from 31 March 2026.

The 2026 Tsukimi season is the 35th, and McDonald's is marking it with eight limited products, three of them new. The first phase ran from 2 September and the second from 24 September, a schedule that cuts the limited run itself into stages within a single autumn.
