Kodansha to release new sticker collections in Japan

Kodansha is releasing several new sticker collections in Japan throughout late September 2026.

One release is the ‘Replica Edition Adult Encyclopedia Sticker Book Best Selection,’ produced by Kamio Japan. This collection features 561 stickers across 16 diverse themes, including cats, dogs, ancient Egypt, succulents, and retro stationery. Priced at 1,650 yen, the book has already secured a reprint before its official September 25 release.

Additionally, a ‘Chiikawa What Will You Get? Sticker Collection’ will be available starting September 28. Based on the popular series by Nagano, these A5-sized sticker sheets are sold in random envelopes for 660 yen each. The collection includes eight character designs—such as Chiikawa, Hachiware, and Usagi—plus one secret design. A total of 50 sheets are included per box, with three special bonus items distributed among them.
