Baskin-Robbins Japan × Pokémon 2026: Only the Double Cup Gets a Sticker (Aug 1–31)

Baskin-Robbins Japan — known here as サーティワン (Thirty-One) — starts its Pokémon campaign, 31ポケ夏！ (31 Poke-Natsu), on August 1, 2026. It runs through August 31.

The headline item is a sundae served in a Poké Ball–shaped cup. In Japan the Poké Ball is called a Monster Ball (モンスターボール), which is why the product name reads the way it does. There's also a Ditto soda that turns purple as you stir the two syrups together, plus 30 collectible stickers.

Only one item on the menu comes with a sticker, though, and the sundae is capped at three per order through August 9. Walk in without knowing either and you'll miss what you came for.

Stickers come with the Pokémon Double Cup and nothing else. Buying any other item won't get you one.

The 2026 campaign at a glance

By the company's own count, there were somewhere over 1,500 stores nationwide as of the end of December 2025. : Store locator

If you come across a Japanese page listing this campaign as running "until September 3," check the year. Pokémon's own site carries that date with no year attached, and September 3 falls on a Wednesday in 2025 but a Thursday in 2026.

Stickers: Double Cup only

There are 30 Special Pokémon Stickers, a number the company ties to Pokémon's 30th anniversary.

You get one sticker per Pokémon Double Cup. The Double Cup holds two scoops, but it's still one sticker per cup. Two stickers means two cups.

You can't pick the design. The release adds that the cup may not be yours to pick either, so which of the three artworks — Grass, Fire, or Water — you end up with isn't guaranteed.

Stickers run to August 31, but the release says they end when stock does. The Double Cup costs ¥510 small and ¥760 regular, the same as an ordinary double, so there's no premium for taking this route.

Monster Ball Sundae: three per order through August 9

From August 1 (Sat) to August 9 (Sun), the sundae is limited to three per group, per transaction. A family of four cannot buy one each during those nine days.

That nine-day window is the only limit the company has announced. Nothing in the release says what happens from August 10. If you need four or more at once, it's worth calling the branch first.

The 2026 lineup

ピカチュウのボルテッカー ～パインスカッシュ～ / Pikachu's Volt Tackle ~Pine Squash~ (¥420)

Yellow pineapple-flavored sorbet paired with white cider-flavored sorbet — cider in Japan means a clear lemon-lime soda, not the apple kind — plus red popping candy.

Baskin-Robbins describes the candy as standing in for Pikachu's cheeks and the crackle of electricity, and says there's 31% more of it than in Popping Shower (ポッピングシャワー), the chain's standard popping-candy flavor. At ¥420 it costs the same as any regular single, so you're not paying extra for the tie-in.

モンスターボール サンデー / Monster Ball Sundae (¥820)

One small scoop of your choice under whipped cream and a large Pikachu chocolate. Separately, a decorative pick — the ornament on a little stick — comes in one of three designs, Bulbasaur, Charmander, or Squirtle, and it's handed out at random.

The cup itself is shaped like a Poké Ball, and the company suggests reusing it as a small container once you're done. Carry it home and it doubles as a souvenir.

メタモン クラッシュソーダ / Ditto Crush Soda (¥760)

Crushed ice and soda, with red grape syrup and blue pineapple syrup that the company says mix into Ditto's shade of purple as you stir.

There's grape jelly in there too, and you pick one small scoop of ice cream to go with it. The stirring is the whole point, which makes this the one to order with kids at the table.

ポケモン ダブルカップ / Pokémon Double Cup (small ¥510 / regular ¥760)

Image used with permission

Two scoops of your choice. The cup artwork comes in Grass, Fire, and Water versions, each showing the starter Pokémon of the nine regions alongside Pikachu. The spoon comes in three designs, handed out at random.

Two cakes that stay year-round

The two cakes work differently. The release gives their sales period as "August 1 (Sat) – ongoing," so they don't disappear at the end of the month. What doesn't carry over is the box.

These are frozen cakes, so they only make sense if you have somewhere to keep them — the free cold pack only buys you 30 minutes. If you're in a hotel without a freezer, the Double Cup is the version of this campaign you can actually take part in.

The two cakes are sold year-round. The thing to hurry for is the limited-quantity box that comes with one of them.

ポケモン アイスクリームケーキ ピカチュウ / Pokémon Ice Cream Cake Pikachu (¥3,800)

Image used with permission

Roughly 15 cm (5.9 in) across and 6 cm tall — a size 5 in gō (号), the sizing system Japanese cake shops use. It's made with Popping Shower and strawberry, decorated with a party hat and a bright red bow-tie pick.

The limited quantity applies to the Pikachu-design box rather than the cake itself, so buy early only if you want the packaging.

ポケモン パレット６ / Pokémon Palette 6 (¥4,200)

Image used with permission

A size-5 cake, roughly 16 cm (6.3 in) across and 5 cm tall, topped with chocolates of Pikachu, Eevee, Lucario, Ditto, Charizard, and Sylveon — six characters, which is where the name comes from.

The release says eight flavors, so don't read the "6" as a flavor count. Nothing in it says whether you choose those flavors yourself.

Variety boxes for sharing

A takeout box you fill with scoops. The nine regions' starter Pokémon appear on the packaging, and more of them show up as the box gets bigger. The count is fixed at 4, 6, 8, or 12 — nothing in between.

There is also a ポケモン サマースペシャルセット (Pokémon Summer Special Set) — nine scoops in a Poké Ball–design box, at ¥3,520 small and ¥4,100 regular — which the company does flag as limited in quantity.

At the small size, the nine-scoop set is ¥3,520 against ¥3,400 for twelve scoops. The variety box gives you more ice cream for less; what the set adds is the Poké Ball–design packaging, two stainless spoons, and nine sundae spoons.

At regular size it flips: the set is ¥4,100 against ¥4,200 for the box. The set is cheaper there, but it's still nine scoops rather than twelve.

Baskin-Robbins basics: sizes and how to order

The "31" in the name comes from the idea of a different flavor for each of the 31 days in a month — that's the company's own explanation, anyway. The standard menu:

You pick from three containers: cone, cup, or waffle cone. The waffle cone costs extra — the official price list shows +¥40. Triple Pop can't be ordered in a cone, and for takeout, doubles and Triple Pops come in cups only.

Ordering a single scoop to go is fine, and the FAQ says stores add a cold pack free for up to 30 minutes. There's no official word on stretching it beyond that. Some items — ice cream drinks among them — can't be sent home with a cold pack at all.

Opening hours vary by branch, so check the individual store before you go — the release doesn't give a start time for August 1 either.

Baskin-Robbins doesn't publish a company-wide payment policy, and whether a branch takes cards or transit IC cards (Suica, Pasmo) varies by store. Carrying cash is the safe move.

The Japanese product names are printed above each item here. Showing one on your phone at the counter is the fastest way to order.

Allergy and nutrition info is listed product by product. Stores use the same scoops and equipment for every flavor, though, and the company says outright that cross-contact is possible. Ask at the counter if this affects you.

What to check before you go

Four things the official announcements don't settle. These are the ones worth a phone call.

• Store-by-store availability: neither the release nor the campaign page says whether any branches are left out of the campaign. The official cake page does note that not every store carries every product, and that prices differ at some stores. If you're going for a cake, call ahead and check.
• Online orders and delivery: there's a pickup service called 31 Mobile Order, and the FAQ says delivery operates "at some stores." Whether either carries the campaign items is up to the branch.
• Reserving a cake: the FAQ recommends ordering early but doesn't require it, and gives no dates for when reservations open or close. Call the branch a few days ahead if you want to be sure.
• Tax-free: no guidance from Baskin-Robbins that we could find. Food eaten on the spot generally falls outside the scheme. Our Japan Tax-Free Shopping Guide explains how the system works and what qualifies.
