Hideaki Sorachi's Gintama manga is the subject of a free-reading promotion on LINE Manga and ebookjapan through May 31, 2026, and the first collected volume of the spin-off Gintama: 3-Nen Z-Gumi Ginpachi-Sensei was released on June 4, 2026, with a comment from Sorachi on the obi.
Hideaki Sorachi's long-running manga series Gintama, which ended its serialization years ago, remains active in the market through promotions and spin-offs. In late May 2026, all 77 volumes of the monochrome edition of Gintama were made available to read for free on LINE Manga and ebookjapan from May 29 to May 31. The three-day campaign coincided with the start of 4DX screenings for the film New Gintama Movie: Yoshiwara in Flames, which began on May 29. The promotion also included a user-voted ranking of the best Gintama episodes and a curated collection of famous scenes on LINE Manga's special page, as well as a separate gacha event from May 29 to May 30 offering chances to win manga coins or time-saving items.
Shortly after, on June 4, 2026, the first volume of the manga adaptation of the Gintama spin-off novel Gintama: 3-Nen Z-Gumi Ginpachi-Sensei was released. The volume features an obi with a comment from original creator Hideaki Sorachi. The spin-off began serialization as a vertical-scroll manga in Jump TOON in October 2025 and also runs in Jump Square. The July issue of Jump Square includes a replaceable cover for the volume. These two stories show Sorachi's franchise continuing to generate new material and promotional activity, with the creator directly involved through his comment on the spin-off volume.
