If you've been hearing about a new ZUTOMAYO collaboration at 7-Eleven stores across Japan, you're picking up on something that launched on September 22, 2026 — but the details might not be quite what some initial reports suggested. We're here to walk you through exactly what this collaboration is, what you can actually get, and how the campaign works, because there's been some confusion about stickers versus other items and what's available where.
The collaboration centers on a new limited-edition gummy product and an online giveaway campaign, both tied to the popular Japanese music group ZUTOMAYO (officially stylized as "ずっと真夜中でいいのに。"). Here's everything we know about what's actually on offer and how you can participate.
The Quick Version
- Kanro released "Zutomayoroshu Lime Ginger Ale Flavor" gummies exclusively at 7-Eleven stores nationwide in Japan on September 22, 2026
- The product comes in five different collectible package designs featuring ZUTOMAYO branding
- This marks the third collaboration between ZUTOMAYO and Kanro's Marosshu gummy line
- A social media campaign on X (Twitter) runs from September 22 through September 28, 2026, offering 100 winners exclusive prize sets
- The campaign is online-only; we have not confirmed any in-store sticker giveaway promotion
What the New ZUTOMAYO Gummies Are and Where to Find Them
The heart of this collaboration is a new flavor in Kanro's Marosshu gummy series, called "Zutomayoroshu Lime Ginger Ale Flavor" (ずとマロッシュ ライムジンジャーエール味). This is the third time ZUTOMAYO and Kanro have teamed up for a Marosshu product, building on the success of their previous collaborations. The gummies hit shelves at 7-Eleven stores across Japan on September 22, 2026, as an exclusive product you won't find at other retailers.
What makes this release particularly appealing to collectors is that the gummies come in five distinct package designs, each featuring different ZUTOMAYO artwork and branding. This means fans can hunt for their favorite designs or try to collect the complete set while enjoying the lime ginger ale flavor — a refreshing, slightly spicy-sweet combination that's become popular in Japanese candy collaborations.
The product is exclusive to 7-Eleven, though as with most convenience store exclusives in Japan, not every single location may carry it, particularly very small branches or those in remote areas. If you're planning to pick some up, larger urban 7-Eleven locations are your best bet, especially in the first few days after launch when stock is freshest.
How the Social Media Campaign Works
Alongside the product launch, Kanro is running a week-long giveaway campaign on X (formerly Twitter) that we think is what some people may have confused with an in-store promotion. The campaign started at 9:00 AM on September 22, 2026, and runs through 11:59 PM on September 28, 2026. It's officially called the "Zutomayoroshu Mayonaka Immersion Set" campaign (ずとマロッシュ真夜中没入セット).
Here's how to enter: First, you need to follow the official Kanro X account (@kanro_pr). Then, you'll need to find the designated campaign post on their feed and create a quote-post (a repost with your own comment) that includes both the hashtag #ずとマロッシュ and a specific phrase that Kanro indicates in the campaign instructions. The mechanics are straightforward, but make sure you include both elements — the hashtag and the required phrase — or your entry won't count.
The campaign will select 100 winners by lottery from all eligible entries. Each winner receives the "Mayonaka Immersion Set," which is a substantial prize package. According to official information from Kanro, the set includes all five package designs of the new Zutomayoroshu Lime Ginger Ale gummies, plus three other Marosshu flavors (grape soda, ramune, and fresh cola), and an exclusive Zutomayoroshu original keychain featuring the "mejirushi" (trademark mark) design. It's a genuinely nice prize if you're a fan — not just the collaboration gummies, but also the other flavors and an exclusive item you can't buy anywhere.
About the Sticker Reports: What We Can Confirm
We've seen some reports mention a sticker giveaway campaign at 7-Eleven stores starting on September 24, 2026, tied to purchasing Kanro products. However, we haven't been able to find official confirmation of such a campaign in materials from either 7-Eleven or Kanro as of September 21, 2026. It's possible there's confusion with last year's collaboration, which featured a different kind of in-store promotion.
In September 2025, 7-Eleven did run an in-store campaign where customers who purchased two eligible sweets products at once received one of five different A5 clear files (plastic folders) featuring ZUTOMAYO designs. That campaign ran from September 25 through October 8, 2025, and was quite popular, running out of supplies at many locations before the official end date. The format — buy certain products, get a collectible item — is similar to what a sticker campaign might look like, which may be where some of the current confusion stems from.
If a sticker or similar in-store promotion for this 2026 collaboration exists, the details haven't been widely published as of our writing. We'd recommend checking with your local 7-Eleven or watching the official 7-Eleven Japan social media channels if you're specifically looking for an in-store giveaway. The confirmed promotion we can point you to is the X campaign detailed above, which definitively runs through September 28, 2026.
Why ZUTOMAYO Collaborations Keep Drawing Attention
ZUTOMAYO has become one of the most collaboration-friendly music acts in Japan's current scene, and there are good reasons why brands like Kanro and retailers like 7-Eleven keep partnering with them. The group, led by the enigmatic composer and vocalist ACAね (Acane), has built a massive following since their 2018 debut, particularly among younger audiences who discovered them through streaming platforms and social media.
Their visual identity — distinctive character designs and dark-but-playful aesthetics — translates beautifully to product packaging and merchandise. Unlike some artist collaborations that feel forced, ZUTOMAYO's branding actually enhances packaging design, making even everyday items like gummy candy feel special and collectible. The five different package designs for this gummy release aren't just marketing; they're genuinely appealing to fans who want to display them or collect the complete set.
There's also something to be said for the strategic choice of convenience stores as the collaboration venue. In Japan, convenience stores are cultural hubs, particularly for younger people, and limited-edition items create real foot traffic. When you combine that with ZUTOMAYO's strong social media presence and the built-in shareability of limited-edition finds, you get campaigns that generate their own momentum. Fans post their finds, others get interested, and the cycle continues — which is exactly what brands hope for in these partnerships.
What People Are Saying
The collaboration announcement generated immediate excitement from ZUTOMAYO fans across Japanese social media. One fan posted their relief at the 7-Eleven exclusivity, writing that they were happy they wouldn't have to "hunt across multiple store chains this time" — a reference to how exhausting it can be to track down collaboration items spread across different retailers. Others immediately began planning their approach to collecting all five package designs.
Several users expressed particular interest in the lime ginger ale flavor itself, with one commenter noting that "the slightly spicy, refreshing flavor actually fits ZUTOMAYO's vibe really well" — suggesting that flavor choice wasn't random but thoughtfully matched to the group's aesthetic. The excitement extended beyond just product collectors to genuine candy enthusiasts curious about the flavor combination.
We also noticed fans sharing memories of the previous Marosshu collaborations and comparing notes on which designs they'd managed to collect. The community aspect of these limited releases is clearly part of the appeal — it's not just about the product itself, but the shared experience of hunting for items and showing off what you found. One user summed it up nicely: "This is why I always check 7-Eleven on my way home. You never know when something good drops."
Frequently Asked Questions
When exactly can I buy the ZUTOMAYO gummies at 7-Eleven?
The gummies launched on September 22, 2026, and should be available at participating 7-Eleven stores across Japan for as long as stock lasts. Limited-edition items like these typically remain available for several weeks, though popular designs may sell out earlier at busy locations.
Can I enter the X campaign if I don't live in Japan?
The campaign doesn't explicitly restrict entries by location, but the prizes would need to be shipped to a Japanese address according to typical Kanro campaign rules. If you have friends or a forwarding service in Japan, entry is possible, but international direct shipping is unlikely to be offered.
Are the five package designs random, or can I choose which one I get?
Package designs are typically distributed randomly to stores, and you won't know which design you're getting until you pick up the package. Some stores may receive more of certain designs than others, so if you're hunting for a complete set, you may need to visit multiple locations or make multiple purchases.
How much do the gummies cost?
Specific pricing wasn't included in the official announcements we reviewed, but Marosshu gummies typically retail for around 150-200 yen per package at Japanese convenience stores. Prices may vary slightly by location.
Is there any other ZUTOMAYO merchandise available through this collaboration?
Apart from the gummies themselves and the X campaign prize set (which includes the exclusive keychain), we haven't confirmed additional merchandise tied specifically to this September 2026 collaboration. The prize set keychain is the only confirmed exclusive item beyond the gummy packages themselves.
Making the Most of Limited-Time Collaborations
If this collaboration has caught your interest, the key dates to remember are that the gummies became available on September 22, 2026, at 7-Eleven stores, and you have until September 28, 2026, to enter the X campaign for a chance at the prize set. Whether you're in it for the collectible packaging, the candy itself, or the chance to win exclusive items, acting relatively quickly gives you the best shot at finding all the designs you want before stock runs low at popular locations.
We'll update if we hear any official word about additional in-store promotions or giveaways beyond what we've confirmed here. For now, the X campaign and the product itself are the two confirmed ways to engage with this latest ZUTOMAYO collaboration. If you're a fan of the group or just enjoy trying limited-edition Japanese snacks, this one's worth checking out while it's still available.
