Bones business profile: ownership, model, and strategy
Bones is one of Japan's best-known independent studios, but its corporate structure changed in 2024 and its financials are not fully public.
Published: 2026-08-19. Updated: 2026-08-19.
Short answer: Bones Inc. is a Japanese animation studio founded in October 1998 by former Sunrise staff including Masahiko Minami. It is a private, independent company based in Suginami, Tokyo. Bones does not publish audited financial statements. Available third-party estimates place its employee count at roughly 110 to 120 people and its annual revenue in the low single-digit billions of yen, but these figures are not independently verified. In 2024 the studio spun off its production division into a new company, Bones Film.
What Bones is and who owns it
Bones Inc. is a Japanese animation production company established in October 1998 by Masahiko Minami, Hiroshi Osaka, and Toshihiro Kawamoto, all former Sunrise staff. The studio's name comes from Minami's wish to create work 'close to the bone,' or fundamental to animation craft. It remains a private, independent company.
In 2024, Bones restructured by spinning off its animation production division into Bones Film Inc., which began operations on October 1, 2024. Bones Film is described as a production subsidiary that took over the studio's day-to-day animation work. The exact ownership relationship between Bones and Bones Film has not been detailed in public sources.
How Bones makes money
Bones plans and produces television and theatrical animation. Its major franchises include My Hero Academia, Bungo Stray Dogs, Mob Psycho 100, Fullmetal Alchemist, Eureka Seven, and Noragami. Revenue comes primarily from production fees paid by production committees and from participation in rights for original works it co-owns.
The studio also operates the Bones Store, an official e-commerce channel for Blu-ray, DVD, and merchandise sales. This direct-to-fan revenue is a secondary income stream compared with production fees and rights.
What public financial data exists
Bones is not listed and does not publish audited financial statements. Third-party business databases give conflicting figures: one source estimates annual revenue at JPY 1.88 billion with 63 employees, while recruitment data for the Bones Film group cites revenue of JPY 4.272 billion and 119 employees as of 2024. These numbers cannot be independently reconciled from public filings.
The divergence likely reflects whether the estimate covers Bones alone or the Bones Film group, and whether it is based on actual filings or model-based estimates. Without access to official-gazette filings, any revenue figure should be treated as unverified.
Financials are not fully public: Bones does not disclose audited revenue or profit. The figures cited by third-party databases conflict and cannot be verified from public filings. This article therefore states only the structure and operating facts that are confirmed.
Bones' place in the industry
Bones is widely regarded as one of Japan's top independent animation studios, known for high-action and character-driven productions. Its work on My Hero Academia and Bungo Stray Dogs has made it a household name among global anime audiences.
Industry data from Teikoku Databank shows that primary contractor anime studios averaged annual revenue of JPY 2.75 billion in 2024. Bones likely sits near or above that average when franchise titles are active, but its revenue will fluctuate with the number and scale of productions in any given year.
Strategy and outlook
Bones' strategy has long been to prioritize creative quality and franchise longevity over volume. The 2024 spin-off of Bones Film suggests an effort to create a more focused production entity while the parent company may manage rights, merchandise, and store operations.
The studio's outlook is tied to the conclusion of My Hero Academia and the continuation of Bungo Stray Dogs, two of its largest current franchises. Its independence gives it creative control, but also exposes it more directly to production-cost pressure and scheduling risk than group-backed studios.
