BIOGRAPHY

Chatayodom Hiranyasthiti (Thai: ชาตโยดม หิรัญยัษฐิติ; born 3 August 1976 in Bangkok), known by the nickname Chai, is a Thai actor, model and director with a career spanning three decades of Thai television.

He has been recognised repeatedly by the Thai industry: Best Actor at the 2007 Komchadluek Awards, Best Leading Actor at the 2008 TV Gold Awards, Best Supporting Actor in 2011, and two wins at the 2024 Komchadluek Awards for To the Moon and Back and The Betrayal. He was named Actor of the Year at the 9Entertain Awards in June 2024.

In One31’s 2026 historical BL series The Edge of Horizon (อรุณรุ่ง) he plays Prince Vasin, the father of Prince Thinnakon and the figure whose refusal to accept his son’s bond with a commoner drives the separation at the centre of the story.

BLGLFlix editorial view

The most decorated actor documented on this site plays the father who will not accept his son’s relationship. That casting is doing something.

Chatayodom Hiranyasthiti has thirty years of Thai television behind him and a shelf of prizes to go with it: Best Actor at the Komchadluek Awards in 2007, Best Leading Actor at the TV Gold Awards in 2008, Best Supporting Actor in 2011, two more Komchadluek wins in 2024 for To the Moon and Back and The Betrayal, and Actor of the Year at the 9Entertain Awards the same year.

In The Edge of Horizon he is Prince Vasin, whose refusal to accept his son’s bond with a commoner is the engine of the separation the whole series turns on. A production putting an actor of that standing into the obstacle role rather than a sympathetic one is spending its most credible performer on the position the audience is meant to argue with.

He also directs, which the profession field records. Performers who have sat in both chairs are rare here, and it tends to show in how they play scenes built around what a character refuses to say.
