The call

Kodansha's profit rose as its home market shrank, with copyright rulings and licensing income doing the work while AI presses on translation costs, not on ownership of the stories themselves.

Kodansha owns and publishes famous manga stories like Attack on Titan and Sailor Moon, and makes money by selling those stories in print, digital, and through licensing deals to other companies. It is hard to replace because it owns the legal rights to these stories, and courts have sided with Kodansha against companies that try to copy them without permission, which AI tools cannot easily get around. The big question is whether Kodansha will use government money to speed up its translation work with AI tools, which could help it compete faster against larger rival publishers like Shueisha, but the company has said it does not use AI yet.

Why
01
AI pressure: AI translation/localization tools (e.g. tools targeted by METI subsidy push). AI targets the translation and localization layer of manga, a cost center, not the copyrighted IP itself. Could AI do the core job? Unlikely.
02
Bigger players: Shueisha and Korean webtoon platforms (Kakao Piccoma, NAVER Webtoon). Shueisha outsells Kodansha in manga circulation and webtoon platforms compete on vertical-scroll format and reader attention. Could a giant copy it? No, they are blocked.
03
What protects it. Copyright ownership of flagship franchises plus courtroom enforcement, shown by the ¥500M Tokyo court judgment against Cloudflare.
What would change this call
METI's ¥11.5B AI translation subsidy program is formally announced and Kodansha's response to it. Shows whether Kodansha adopts AI localization or keeps lagging faster-moving rivals like Shueisha.
Japan's domestic manga market sales figures for 2026 (ICv2 or industry tracking) versus 2025's 2% contraction. Shows whether the print market decline is accelerating or stabilizing.
Outcome of any Cloudflare appeal or new AI copyright litigation involving Kodansha. Tests whether courts continue upholding rights-holder standing against AI-generated infringement.

  • Government subsidy pressure to adopt AI translation conflicts with Kodansha's public 'no AI' stance. Severity: medium
  • Vertical-scroll webtoon format from Korean platforms could permanently shift reader attention from traditional manga. Severity: medium
  • Ongoing generative-AI copyright disputes (Sora2, piracy sites) require continued costly legal enforcement. Severity: low

Questions people ask
Is Kodansha profitable in 2025?
Yes. For its 87th fiscal period (Dec 2024 to Nov 2025), Kodansha reported revenue of ¥169.17 billion, down about 1.1% year over year, but net profit rose roughly 19.4% to ¥11.19 billion, driven by a shift toward higher-margin digital and licensing income (as of 2025-11-30, per note.com commentary dated 2026-03-07).
Could AI replace Kodansha's manga business?
Unlikely in the near term. AI mainly threatens the translation and localization layer, not Kodansha's core asset: copyrighted franchises like Attack on Titan and Sailor Moon. Kodansha publicly stated 'No AI was used' in its K MANGA/Young Magazine USA translations as of September 2025, and won a legal case against Cloudflare over piracy in November 2025.
Who owns Kodansha?
Kodansha is a privately held, family-controlled company, never publicly listed. Descendants of founder Seiji Noma, partly through the Noma Cultural Foundation, historically hold roughly 39.2% of shares. The current president is Yoshinobu Noma, the seventh-generation family president, in office since 2011.
Is Shueisha a bigger competitor than Kodansha?
Yes, Shueisha is generally regarded as the larger Japanese manga publisher, owning Weekly Shonen Jump and franchises like One Piece and Dragon Ball, and it has invested alongside Shogakukan and Kadokawa in AI translation platform Mantra used in Manga Plus, as reported through mid-2026.
Is Kodansha a safe company to join, or are layoffs likely?
Kodansha's headcount has stayed roughly flat at 900 to 970 employees for years, listed at 948 as of September 2025. New hires fell to 22 in fiscal 2024 from 27 in fiscal 2023, but there is no reported layoff activity; it is a mature, stable, century-old family publisher.
Did Kodansha win its lawsuit against Cloudflare?
Yes. On November 19, 2025, a Tokyo District Court ruled in favor of Kodansha along with Shueisha, Shogakukan and Kadokawa, finding Cloudflare liable for aiding manga piracy sites and awarding roughly ¥500 million in damages to the publishers.
