Sotsu anime business profile: Gundam rights agency and Bandai Namco integration
Sotsu built its reputation on Gundam licensing, but after a 2026 reorganization it is exiting anime IP management and returning to advertising services.
Published: 2026-08-19. Updated: 2026-08-19.
Short answer: Sotsu Co., Ltd. is a Japanese advertising and content-rights company founded in 1965. It became best known as the rights agency for the Mobile Suit Gundam franchise. Bandai Namco Holdings acquired Sotsu through a tender offer in 2019, and on April 1, 2026 Bandai Namco Filmworks absorbed Sotsu's Gundam-related business and IP production operations while Bandai Namco Music Live took over Sotsu Music Publishing. Sotsu continues as a non-IP company focused on sports advertising and broadcast agency services.
What Sotsu is and who owns it
Sotsu Co., Ltd. was established in October 1965 and is headquartered in the Ginza district of Tokyo. The company entered anime production in the 1970s and became a core partner in the Gundam business, managing domestic and overseas licensing windows and commercialization for the franchise.
Bandai Namco Holdings acquired Sotsu through a tender offer in 2019 with the long-term goal of internalizing Gundam licensing. Sotsu was delisted from the Tokyo Stock Exchange and is now a wholly owned subsidiary.
The April 2026 reorganization
Effective April 1, 2026, Bandai Namco Filmworks absorbed Sotsu's Gundam-related business and IP production operations. The move centralized Gundam licensing, planning, and rights management under Bandai Namco Filmworks, which already served as the producer and copyright holder for the series.
At the same time, Bandai Namco Music Live integrated Sotsu Music Publishing through an absorption split, consolidating control of music copyrights, master recordings, and related assets. After the carve-out, Sotsu retained non-IP activities such as sports advertising, stadium signage, and broadcast agency services.
Current anime revenue is not disclosed: Sotsu no longer files standalone public financials as a Bandai Namco subsidiary. Its Gundam-related revenue historically came from licensing and production-committee participation, but the amount was never separately disclosed in recent public filings.
Corporate profile
Before delisting, Sotsu was listed on the Tokyo Stock Exchange JASDAQ market with stock code 3711. Its capital was JPY 414.75 million and its fiscal year ended in March. The company employed a small team focused on rights management and advertising.
Sotsu Music Publishing, founded in 2003, handled music publishing for animated works. That subsidiary is now part of Bandai Namco Music Live.

Role in the Gundam franchise
Sotsu managed licensing windows and commercialization for Mobile Suit Gundam for decades. Its role was to coordinate toy, game, apparel, and media licensees and to collect royalties on behalf of the production committee. This made it a gatekeeper for one of Japan's largest animation properties.
The 2026 integration ends that independent role. Bandai Namco Filmworks now controls both animation production and licensing for Gundam, which the group expects to streamline negotiations with global partners.
Strategy after the carve-out
After transferring its anime IP assets, Sotsu is repositioning around sports advertising and broadcast agency services. Those are lower-profile businesses than Gundam rights management but also less dependent on a single franchise.
The reorganization reflects Bandai Namco's broader strategy of consolidating Gundam rights inside its own group to accelerate global expansion. For Sotsu, the change means the company no longer sits at the center of anime licensing.
