Career Journey: Spearheading JoJo’s Bizarre Adventure
When Warner Bros. Japan first considered adapting Hirohiko Araki’s legendary, multi-generational manga epic JoJo’s Bizarre Adventure into a television anime series, Ōmori was initially hesitant due to the manga's retro art style and its stark contrast with modern industry trends. However, recognizing its profound literary and cultural merit, he took on the monumental challenge as producer.
Working closely with animation studio David Production, Ōmori oversaw the production of every major season from the *Phantom Blood* and *Battle Tendency* introduction all the way through *Golden Wind*, transitioning to a planning producer role for *Stone Ocean*. He famously fought to secure licensing rights for iconic classic rock songs (such as Yes, The Bangles, and Savage Garden) to serve as ending themes, creating an auditory signature that defined the franchise's global identity.

Beyond his defining work on the JoJo universe, Ōmori’s production credits span a vast spectrum of genres, proving his versatility as an industry executive:

Within the industry and among international fans, Ōmori was celebrated for his approachability, enthusiasm, and deep respect for source materials. He frequently traveled to international conventions like Anime Expo to engage directly with overseas fans, famously recalling how hearing crowds in Italy sing "Fighting Gold" inspired him to push for clearer English-language vocal adaptations. His sudden passing in June 2024 brought an outpouring of grief from creators, voice actors, and millions of fans across the globe who credited him with bringing their favorite manga pages to vibrant animated life.
