Tezuka Osamu Memorial Day

What Is Tezuka Osamu Memorial Day?

Every February 9th is "Tezuka Osamu Memorial Day" (漫画の日, Manga no Hi) in Japan — specifically the anniversary of the death of Osamu Tezuka (手塚治虫, 1928–1989), who died on February 9, 1989. As the "God of Manga" (漫画の神様), Tezuka's February 9th death anniversary is observed as a second "Manga Day" alongside the November 3rd birthday commemoration — providing two annual occasions to honor the creator who defined modern Japanese manga and animation. (See also November 3rd, Manga Day, for full details on Tezuka's life and legacy.)

Tezuka's Final Years

Tezuka Osamu died on February 9, 1989, at age 60, from stomach cancer — reportedly working on manga projects until just days before his death. His final words, according to staff members present, were "Please, let me work" (頼む、仕事させてくれ, Tanomu, shigoto sasete kure) — a statement that perfectly encapsulates the extraordinary creative drive that had produced over 700 manga series and 150,000 pages across four decades of work.

The Manga World's Loss

Tezuka's death was mourned across Japan and by manga and animation communities worldwide. The scale of his influence was apparent in the tributes that poured in from artists, writers, and fans whose creative lives had been shaped by his work. In the 30+ years since his death, Tezuka's legacy has only grown — his characters (Astro Boy, Black Jack, Princess Knight, the Phoenix) remain active in manga, animation, merchandise, and cultural discourse, managed by Tezuka Productions.

Tezuka's Continuing Influence

The manga and anime tradition that Tezuka established continues to shape global popular culture in ways that would have astonished observers in 1989. Japanese anime and manga have achieved extraordinary global reach — streaming platforms carry anime to hundreds of millions of viewers worldwide; manga is translated into dozens of languages; and the visual language and narrative conventions that Tezuka pioneered are recognizable from Tokyo to São Paulo to Paris. Every contemporary manga artist works, consciously or not, within the tradition he created.

Fun Facts

• Tezuka Productions: Tezuka Productions (手塚プロダクション), the company managing Tezuka's intellectual property legacy, continues to develop new animations, merchandise, and adaptations of Tezuka's characters — ensuring that Astro Boy, Black Jack, and the Phoenix remain culturally active decades after their creator's death.
• AI Tezuka: In 2020, a team of AI researchers and manga artists created "Paionia" — a short manga created with AI assistance trained on Tezuka's works, attempting to channel his visual style and narrative sensibility into new stories. The project raised profound questions about creativity, authorship, and the possibility of extending the work of deceased artists through artificial intelligence.
