Stranger Things Announces New Collab with Japan’s Iconic Monchhichi
Sekiguchi has officially announced a new collaborative merchandise line featuring the popular character Monchhichi and the Netflix series Stranger Things.
This unique collection commemorates the release of the final part of Season 5, which serves as the concluding chapter of the hit sci-fi adventure series.
The collaboration marks the first time that the Stranger Things franchise has partnered with a Japanese mascot character.
The designs aim to express the dark and mysterious atmosphere of the series using a distinctive black and red two-tone color scheme.
The lineup features two distinct keychain plushies that blend the adorable Monchhichi aesthetic with iconic elements from the show.
The “Hellfire Club” version features a boy Monchhichi wearing the club’s logo t-shirt and a cap that pays homage to Dustin’s “Thinking Cap.”
Detailed touches on this figure include a sewn-on walkie-talkie and a special collaboration label stitched onto the back.
The “Bib” version features a girl Monchhichi wearing a bib printed with the Stranger Things logo to highlight the collaboration.
This design utilizes the character’s signature twin-tails, which can be stood up to resemble the telekinetic powers of the character Eleven.
Both items are designed as palm-sized keychains and include a ball chain for attaching to bags or accessories.
The “Hellfire Club” version is priced at 3,850 yen (approx. $26.00 USD / £20.00 GBP), while the “Bib” version is available for 3,300 yen (approx. $22.00 USD / £17.00 GBP).
Sales will begin at Monchhichi official shops and character specialty stores nationwide in Japan on Monday, January 12, 2026.
The items will also be available for purchase through various online character goods stores starting on the same date.
