Atomu Mizuishi

Mizuishi's career started not on a film set but on a stage — his 2012 debut came through *The Musical Prince of Tennis 2nd Season*, where he played Renji Yanagi (TMDB). Stage musicals are a serious training ground in Japan's entertainment ecosystem, and that foundation shows. He's one of those actors who carries physical presence into every role, which probably explains why tokusatsu producers kept calling. The genre television work came quickly. His role as Crow (Makai Knight) in *Garo: Makai no Hana* (2014) put him in a franchise known for its darker, more stylized take on the hero genre. Then came *Kamen Rider Zi-O* (2018), where he portrayed Ryuichi Sakuma/Another Fourze — a villain-adjacent role in a series that leaned hard into nostalgia for the broader Kamen Rider universe, requiring him to embody a character fans already had strong feelings about (Wikipedia, Kamen Rider Wiki). That's a tricky assignment for any actor, and Mizuishi handled it in a way that earned him notice beyond the existing fanbase. His run as Shiguru Oshikiri/Kiramai Blue in *Mashin Sentai Kiramager* (2020) was arguably his highest-profile tokusatsu role to date — a full-series commitment in a Super Sentai entry that aired during an extraordinarily disrupted production period globally. Recent years show a deliberate broadening. *My Personal Weatherman* (2023) placed him in a contemporary drama context far removed from armored heroes, and the *Baby Assassins* film series offered something closer to stylized action cinema. Upcoming projects — *Masked Ninja Akakage* (2025) and *No.1 Sentai Gozyuger* (2025) — suggest he's not abandoning the genre work that made him, even as he builds out a more varied filmography. Thirteen-plus years in. Still going.
