Bandai's Candy Division is releasing a limited collaboration between Project SEKAI COLORFUL STAGE! feat.

If you're wondering what exactly comes in these packages, which characters are featured, and how this ties into the broader collaboration between these two franchises, we've gathered all the confirmed details.
The Quick Version
- Bandai Candy is launching Project SEKAI × Tamagotchi collaboration gummies on June 22, 2026 in Japan
- Each package contains soda-flavored gummies and at least one collectible metallic plastic card
- Cards feature exclusive collaboration illustrations pairing characters like Hatsune Miku with Mametchi
- The candy extends the Project SEKAI × Tamagotchi collaboration that ran in-game from September 19 to October 10, 2025
- Online export retailers are listing the product, though official international availability hasn't been announced
What Comes in Each Package
The collaboration gummies follow Bandai Candy's popular card-attached candy format, which has become a staple for anime and game merchandise in Japan. Each package reportedly contains a portion of soda-flavored gummy candy alongside at least one collectible card. The cards themselves are described as having a shiny metallic finish, giving them a premium feel that sets them apart from standard paper collectibles.
What makes these cards special are the collaboration illustrations. Rather than simply featuring existing artwork from either franchise, the cards showcase original illustrations created specifically for this partnership. The most prominently featured pairing is Hatsune Miku—the iconic turquoise-haired virtual singer and face of Project SEKAI—alongside Mametchi, the round, friendly Tamagotchi character who has been the franchise's unofficial mascot since the original digital pets debuted in the 1990s.
Product listings show multiple different card designs, suggesting there's a variety to collect, though the exact number of card types in the full set hasn't been officially confirmed. This is typical for Bandai's collectible candy lines, which often feature anywhere from six to twelve or more variations to encourage collecting and trading among fans.
The Collaboration's Background and Connection
This candy release isn't a standalone partnership—it's part of a larger collaboration between Project SEKAI and Tamagotchi that began in 2025. The in-game collaboration was first announced on July 28, 2025 during the 22nd episode of the Project SEKAI Broadcast Station, the game's regular livestream update show. The actual collaboration event ran on the Japanese server from September 19 to October 10, 2025.
During that in-game event, players could obtain special four-star gacha cards featuring Project SEKAI characters styled with Tamagotchi themes, and the collaboration also included decorative furniture pieces for the game's "My SEKAI" customization feature. Specific four-star collaboration cards unlocked matching Tamagotchi-themed furniture items. A login campaign that ran from September 19 to October 5, 2025 distributed special items including "Onigiri" and "Gotchi Pieces" to participating players.
The candy product appears to extend this collaboration into the physical merchandise space, using similar character pairings and visual themes. It's a strategy we've seen frequently with successful game collaborations in Japan—when an in-game event resonates with fans, it often expands into related merchandise like apparel, accessories, and in this case, collectible candy.
Why These Two Franchises Make Sense Together
On the surface, pairing a modern rhythm game with a virtual pet franchise that debuted in 1996 might seem unexpected. But there's a genuine thematic overlap that makes this collaboration work. Both Project SEKAI and Tamagotchi center on the idea of nurturing relationships with digital characters—whether you're raising a Tamagotchi from egg to adult or building bonds with the various units in Project SEKAI through stories and musical performances.
There's also the matter of shared audience. While Tamagotchi originally captured the hearts of children in the late 1990s, many of those original fans are now adults who grew up alongside the evolution of virtual entertainment. Project SEKAI, meanwhile, appeals to a wide demographic that includes both younger players discovering Hatsune Miku for the first time and older fans who have followed Vocaloid culture since Miku's debut in 2007. The nostalgia factor of Tamagotchi combined with the contemporary appeal of Project SEKAI creates a sweet spot for collectors and fans of both franchises.
The visual pairing of characters also plays into what Japanese merchandise culture calls "kawaii"—the aesthetic of cuteness that drives much of the collectible market. Seeing Hatsune Miku's sleek, modern design alongside Mametchi's simple, round charm creates an appealing contrast that translates beautifully to the illustrated cards.
Where and How to Get Them
The gummies are scheduled for release on June 22, 2026 in Japan. Based on how Bandai Candy typically distributes character collaboration products, we can expect these to appear in convenience stores, supermarkets, and hobby shops across Japan. Bandai's candy collaborations usually receive wide distribution, making them relatively accessible for fans living in or visiting Japan.
For international fans, online export retailers have already begun listing the product, though official international distribution hasn't been announced. Some specialty import shops that focus on Japanese snacks and collectibles may also carry them, though often at a markup due to import costs and shipping. The price per package hasn't been officially confirmed, though similar Bandai card-attached gummy products typically retail in the range of 150 to 250 yen in Japan.
It's worth noting that collectible candy products like these can sell out quickly, especially during the first few weeks of release when collectors are trying to complete their sets. If you're particularly keen on collecting all the card variations, purchasing multiple packages early may be your best strategy.
The Appeal of Card-Attached Candy in Japanese Pop Culture
Card-attached candy products occupy a unique space in Japanese merchandise culture. They're more affordable than dedicated trading card games or premium figurines, making them accessible to a broader range of fans. At the same time, the collectible element adds value beyond just the candy itself—the cards become keepsakes, tradeable items, and display pieces.
For many fans, these products represent a low-stakes way to engage with a collaboration they're interested in. You're not committing to an expensive piece of merchandise; you're picking up a small treat that happens to come with something collectible. The randomized nature of which card you'll receive adds an element of excitement similar to opening a pack of trading cards, but at a fraction of the cost.
The metallic finish on these particular cards suggests Bandai is positioning them as slightly more premium than standard paper inserts. Metallic or holographic cards tend to be more durable and visually striking, which matters for collectors who plan to display them or keep them in good condition for trading.
What People Are Saying
Fans of both franchises have been sharing their excitement about the collaboration artwork since the product was announced. The pairing of characters has struck a particular chord with collectors who appreciate the thoughtful matching of personalities and visual styles.
"The Miku and Mametchi illustration is so precious! I love how they kept both characters' signature looks while making them feel like they belong in the same world. Definitely going to try to collect all the cards."
Some Project SEKAI players who participated in the original in-game collaboration event have expressed appreciation for getting physical merchandise that commemorates that experience. For players who pulled the special four-star collaboration cards or decorated their My SEKAI spaces with Tamagotchi furniture, the candy cards offer a tangible reminder of that limited-time event.
"I missed out on getting all the in-game collab cards last year, so having these physical ones feels like a second chance. Plus, the metallic finish looks amazing from the preview images—way better than a screenshot of the game cards."
Tamagotchi collectors, meanwhile, have noted how these collaboration cards expand the range of Tamagotchi merchandise available. While there's no shortage of Tamagotchi products on the market, collaborations with modern properties like Project SEKAI introduce the characters to new contexts and art styles that keep the franchise feeling fresh.
"As someone who's been collecting Tamagotchi stuff since the original toys, I love seeing Mametchi and the gang in these kinds of crossovers. The Project SEKAI art style is so vibrant and detailed—it makes the Tamagotchi characters look adorable in a completely different way."
