His screen credits run through a long list of Japanese Boys’ Love and youth titles, among them Old Narcissus (2017), Takumi-kun Series: The Dawn of the Long Tales (2023), 18 Years Old, Spinning Together (2023), Perfect Propose (2024), The Wedding Announcement (2025) and Love Punch! (2026).

In Hold on, Harutora-kun (2026) he plays Shimizu Daiki, Sui’s closest friend, the one person at school who already knows what Sui has been through and has been quietly watching over him.

BLGLFlix editorial view

Read his credits in order and the pattern is hard to miss. Old Narcissus in 2017, when he was seventeen, then a run of Japanese queer and youth titles that has not broken since. Japanese boys’ love behaves less like a genre with a rotating cast and more like a small repertory company. The same performers appear across productions from different studios, on different broadcasters, year after year, and audiences follow them from one to the next in a way that would be unusual for any other kind of Japanese television.

The MEN’S NON-NO contract is not decoration on the record. Exclusive models for that magazine are selected in small numbers and the position has functioned for years as a recognised route into acting work. Naming it explains how someone arrives on a broadcaster’s cast list without a studio trainee scheme behind him, which is the question a Thai or Korean record on this site would usually answer with an agency.

His name is written two ways in the sources. The structured database has 高橋璃央 recorded alongside the variant 高橋里央. The MBS cast page, the Japanese Wikipedia article and Oricon all use the first, so this page follows them. Where an official source and a database disagree on a person’s own name, the official one wins.
