Olivier Kazuma Michihiro was born in 1995 in Osaka, Japan.

Influenced by his family, he was exposed to films and literature from an early age. Although he aspired to pursue a career in visual storytelling, he chose to major in theatre at university in order to broaden his perspective. During his studies, he wrote and directed his first play, Papillon. He subsequently took part in more than twenty theatre and film productions, serving variously as actor, playwright, and director.

Upon graduating, he joined a television production company. After working as an assistant director for drama series and as a video editor for news programs, he became a journalist in the international news department. His work has included coverage of major events such as the G7 Hiroshima Summit and the Paris Olympics.

In 2023, alongside his journalistic work, he wrote and directed TRACÉ, his first full-fledged film since university. Composed entirely of a single sequence shot played in reverse, the film was screened at both domestic and international festivals, where it received awards including Best Film. In 2025, he completed his second film, 23:07.
