Your favorite FamilyMart snack, but bigger—sometimes a lot bigger. On June 2, 2026, FamilyMart, one of Japan's “big three” convenience store chains, kicked off its “Giant All-Star Festival” (巨大オールスター祭). Across roughly 16,400 stores nationwide, the chain has rolled out 14 supersized items made for big appetites.
Prices run from ¥238 to ¥560, including tax. The lineup stars an LL-size version of the cult-favorite “Taberu Bokujo Milk” ice cream—about 2.5 times the usual size—plus a long-awaited LL coffee size and a parade of desserts literally labeled “deka~i” (giant). FamilyMart frames the campaign as a guilty-pleasure indulgence, and it is also part of the run-up to the chain's 45th anniversary this September.
Here's what's worth grabbing, with prices and on-sale dates, even if Japanese convenience store food is new to you.
What Is the “Giant All-Star Festival”?
It's a campaign, launched on June 2, 2026, that brings together oversized items across several categories: coffee, desserts, sandwiches, baked goods, ice cream, and hot snacks. The full lineup includes 14 items. Most are limited runs, but not all of them—the new LL coffee, for example, is set to stay on the menu even after the campaign ends.
The theme, in FamilyMart's own words, is indulgent “guilty consumption”: generous, slightly over-the-top treats made to satisfy a craving.
The sweets, ice cream, baked goods, and hot snacks in particular are often limited in quantity, so popular items may sell out depending on the store and time of day. If something catches your eye, don't wait too long.
The “Deka~i” Giant Desserts
Start with the showstoppers.
Giant Coffee Jelly (¥388, from June 2, limited quantity)
Bitter coffee jelly made with espresso-extracted coffee, topped with a generous layer of whipped cream. It's a satisfying pick for coffee lovers.
Giant Custard Éclair (¥325, from June 2, limited quantity)
A light choux pastry filled with smooth custard cream and coated in chocolate. It feels surprisingly hefty in the hand.
Giant Italian Chestnut Mont Blanc Pudding (¥560, from June 9, limited quantity)
Custard pudding layered with whipped cream and Italian chestnut paste. It is the priciest item in the lineup, and it arrives a week later than most of the others, on June 9.
The Star: “Taberu Bokujo Milk” Ice Cream, About 2.5x Bigger
FamilyMart's beloved “Taberu Bokujo Milk” ice cream is back in an LL size (¥498, limited quantity) that is about 2.5 times the regular size. Made with Hokkaido milk and cream, it is rich but clean-tasting—ideal if you want to go all-in on a Japanese konbini ice cream.
Snack lovers should also look for the Big Crisp Salt Flavor, a 170g bag that is about 3.7 times the standard 45g bag (¥398). Find a star-shaped chip inside, and consider yourself lucky.
From the hot-snack case, the Jumbo Yakitori Negima with Tare Sauce is about double the regular size (¥258).
“FamilyMart's Best Coffee Ever”? The New LL Size
One of the headliners is the long-awaited LL coffee size. FamilyMart has installed new coffee machines across roughly 16,400 stores and is billing the lineup as “the best coffee in FamilyMart history.”
There are four LL options: Iced Coffee LL and Iced Café Latte LL (¥370 each), plus Hot Blend Coffee LL and Hot Café Latte LL (¥320 each). After paying at the register, you make your drink at the machine. For coffee, you can choose light, regular, or strong; for café latte, you can choose milk-rich, regular, or coffee-rich.
And the LL coffee is not going anywhere—it is set to stay on the regular menu after the festival ends.
Bigger Sandwiches and Baked Goods, Too
For something more savory, there are two oversized sandwiches: the Big Triple Egg Sandwich (¥398), about 1.1 times the size of the standard egg sandwich, and the Big Colorful Mix Sandwich (¥430), about 1.4 times the size of the regular mixed sandwich, with ham, egg, tuna, and cheese.
On the baked side, don't miss the Big Financier (¥238), with about 2.9 times the surface area of the regular version and made with French cultured butter, and the Big Cookie (¥258), about double the weight and studded with chocolate chips.
How to Buy Them, and a Few Tips
You can pay with cash, transit IC cards like Suica or PASMO, credit cards, or QR-code payments. Limited-quantity items—especially sweets and ice cream—can sell out depending on the store and time of day, so aim for a morning or early-afternoon visit if there is something specific you want.
With around 16,400 stores nationwide, often near stations and sightseeing areas, FamilyMart is an easy stop between destinations—and a fun way to experience Japan's big-portion convenience store culture.
All Three Big Chains Went Big in 2026
Early summer 2026 turned into a convenience-store supersizing race. FamilyMart's Giant All-Star Festival joined Seven-Eleven's “Kansha Mori”（The campaign has ended.） and Lawson's “Morisugi Challenge,” meaning all three major chains ran oversized promotions around the same time.
If you have the time, a three-chain taste test makes for a fun—and very Japanese—afternoon.
