Kento Hayashi

Kento Hayashi (林遣都) has built a steady actor's career rather than a flash-driven celebrity run, which is part of why he keeps landing material that benefits from credibility over noise. He emerged in film as a teenager, then spent the following years working across movies, television, and stage without getting pinned to one easy persona.

That steadiness plays well inside Human Vapor. Netflix casts him opposite Suzu Hirose as part of a livestreaming sibling setup, which suggests the series wants performers who can make contemporary character dynamics feel natural even when the central premise turns surreal. It is the kind of supporting weight that helps a large ensemble stay coherent.

Hayashi's official site also makes one thing unusually clear: he does not run personal social accounts, a rarity in the current market. That only reinforces the broader impression. He remains an actor-first figure whose value sits on screen, not in always-on platform performance. For a Netflix project rooted in Toho IP, that is a useful texture to have.
