Music · Published 3 October 2026 Swipe more like this →

In short: For over five decades, Ichirou Mizuki became the voice of Japanese animation and tokusatsu. Known to fans as Aniki, or big brother, he recorded over 1,200 songs, shaped the anison genre, and founded the supergroup JAM Project, leaving an indelible mark on the soundtrack of generations of viewers.

Born Toshio Hayakawa in 1948, the artist who would become Ichirou Mizuki began his professional journey in 1968 with the single Kimi ni sasageru Boku no Uta. His career trajectory shifted dramatically in 1971 when he recorded the theme for Genshi Shonen Ryu. This performance marked the beginning of a prolific output that saw him record well over 1,200 songs for film, television, and video games. His dominance in the 1970s, characterized by iconic themes for series like Mazinger Z, Kamen Rider X, and Space Pirate Captain Harlock, earned him the title Emperor of Anime Songs.

Mizuki’s influence extended far beyond his vocal performances. In 2000, he co-founded the supergroup JAM Project alongside other prominent anison vocalists, including Hironobu Kageyama and Rica Matsumoto, to elevate the genre’s profile. He was also a fixture in the industry as a judge for the Animax Anison Grand Prix and a mentor to younger talent. His versatility allowed him to transition into voice acting and live-action roles, appearing in shows like Voicelugger and Tokumei Sentai Go-Busters, where he often contributed both his acting skills and his signature musical style.

Despite facing health challenges, including partial vocal cord paralysis in 2021 and a diagnosis of lung cancer in 2022, Mizuki remained dedicated to his craft. He continued to plan for a celebration of his 50-year career until his death in December 2022 at the age of 74. His legacy is cemented not only by his massive discography but by the enduring respect of his peers and the millions of fans who grew up listening to his powerful, energetic anthems.

His contributions were formally recognized through numerous accolades, including a Lifetime Achievement Award at the 2016 Tokyo Anime Awards Festival and the 2020 Tanita Health Award. Whether through his massive 5-CD box set, Michi ~road~, or his collaborative work with artists like Kang Vorakorn, Mizuki’s work remains the definitive sound of the anison genre, bridging the gap between traditional pop performance and the specialized world of Japanese animation soundtracks.
