A Stamp Line That Started With a Customer Request
Okada Shokai, the Osaka company behind the online stamp shop Hankos and its character-goods storefront FUNCO, says the whole idea came from one customer question: could it make a stamp with a Jujutsu Kaisen character's entire body on it? The result is the Line Art Stamp Collection, and the Culling Game version brings the Season 3 cast of MAPPA's adaptation (Chainsaw Man, Attack on Titan Final Season) to the format, according to the company's PR TIMES release.
Each stamp carries a single character as a clean full-body silhouette in line art. The company pitches the look as understated enough for an adult to use every day without it reading as loud fan merch. The blocks are tall and narrow to fit standing poses, with the largest topping out at 70 mm. Heights differ by character to keep body proportions intact, so a row of them preserves the cast's relative heights.
The block itself is MDF wood, chosen for feel in the hand, and the stamp face is high-detail rubber. Okada Shokai says it holds facial expressions, shading, and clothing details cleanly.
Who Made the Cut
The release counts 18 characters and names 12 of them: Yuji Itadori, Megumi Fushiguro, Yuta Okkotsu, Maki Zenin, Kinji Hakari, Kirara Hoshi, Choso, Hiromi Higuruma, Fumihiko Takaba, Reggie Star, Naoya Zenin, and Sukuna. The FUNCO product page currently shows 17 options in its dropdown, adding Panda, Yuki Tsukumo, Tengen, Ryu Ishigori, and Kenjaku to that list. Whether an 18th pick is still coming is unclear; the release and the store page don't match at the time of writing.
That roster covers the Culling Game arc's newcomers, not just the Tokyo Jujutsu High regulars. Higuruma, Takaba, Reggie Star, and Ishigori are all players introduced in Season 3, and the villain side gets Naoya Zenin, Kenjaku, and Sukuna. Panda is the one character on the store page who doesn't appear in the release's named list.
Stamps are sold individually at ¥2,800 (tax included) per character. The product page lists a lead time of roughly two to three weeks from order to shipment.
From Planners to Tote Bags
Out of the box, the stamps work on paper: notebooks, planners, diaries, book covers, and bookmarks. Okada Shokai also suggests using a separately sold multi-surface ink such as StazOn to print on fabric (tote bags and drawstring pouches), plastic, and metal. The line art is plain black outline, so the company notes that you can color the impressions yourself.
The pitch is one-of-a-kind merch you make rather than buy. The company's own examples are a stamped diary entry, a custom tote, and a book cover.
Part of a Growing Jujutsu Kaisen Stamp Catalog
The Culling Game set is the latest in a run of Jujutsu Kaisen stamp products from Okada Shokai. Earlier Line Art Stamp Collection versions covered Season 2's Shibuya Incident and Hidden Inventory / Premature Death arcs, and six characters from the film Jujutsu Kaisen 0 joined the line in August 2026. The company also sells a Motif Icon Stamp Collection built around character emblems, and in August it added made-to-order Culling Game personal seals in wood-carved and black buffalo horn versions that can be registered as a bank seal in Japan.
Okada Shokai's stated goal is to shake off the hanko's image as a dull office tool. In Japan, the personal seal is used for everything from bank paperwork to package deliveries. The same company makes stamp lines for Haikyu!! and My Hero Academia.
Looking Ahead
The Culling Game stamps are on sale now at FUNCO's Japanese-language store. The release doesn't say anything about overseas shipping, so international buyers will need to check the store's terms or go through a proxy service.
Season 3, Culling Game Part 1, premiered in Japan on January 8, 2026, and streams on Crunchyroll internationally. A teaser for Season 4, Culling Game Part 2, went up on the TOHO animation YouTube channel in June 2026, with Takeshi Sato taking over as director; no broadcast date has been given yet. Gege Akutami's original manga is published in English by Viz Media.
