Shogakukan spent August 2026 responding to the Jojin Kamen scandal on its Manga ONE app. A third-party investigation into the editorial department and creator Shoichi Yamamoto received reports of 44 incidents of misconduct. The company announced findings on August 3, and on August 18 formalized a policy that bars commissioning or maintaining ties with creators found guilty of severe human rights violations, including sexual assault and abuse. The policy adds human rights clauses to future contracts, involves legal and administrative departments in decisions, and disciplines employees involved. President Nobuhiro Oga will take a 50% pay cut for three months, with other executives returning 20% to 30% of their salaries.
Alongside the scandal response, Shogakukan continued its regular publishing activity. On August 17, a new web manga label called MANGABU! launched with 15 series, headed by former Weekly Shonen Jump editor-in-chief Masahiko Ibaraki and former Monthly IKKI editor-in-chief Hideki Egami. The label is operated by FaMH Entertainment, a subsidiary of Fam Group established in May 2025. The same week, the sequel to Kenichi: The Mightiest Disciple released its first collected volume, and the original series went on sale on Kindle. Masami Yuki published a second new Patlabor one-shot in Weekly Big Comic Spirits, following his first new one-shot in May, his first work on the franchise since the original series ended in 1994.
Other Manga ONE titles saw changes. Battle in 5 Seconds went on hiatus as author Miyakokasiwa treats depression, and Chogen Market Heroes: Menko Reverser Kakeru ended its short serialization. The publisher's response to the scandal and its ongoing slate of releases define its current position.
