My Take

Okay, Ken Hirai is one of those artists I never get tired of recommending. He's got this tall, almost model-like frame, and then he opens his mouth and out pours this warm, velvety low register that just melts you—the contrast genuinely catches me off guard every time. The guy quietly stacks up karaoke immortals like "Hitomi wo Tojite" and "Rakuen," yet shrugs himself off as a "song idiot." I love that humility, especially since he'll turn around and dance like a goofball or ham it up in a music video instead of acting like some untouchable diva. From his "Ken's Bar" cover sessions to nearly three decades in, his voice somehow keeps deepening rather than fading. Pure craft, zero ego. Easy artist to root for.

Overview

Ken Hirai is a Japanese singer-songwriter born on January 17, 1972, in Osaka and raised in Nabari, Mie Prefecture. He made his CD debut in 1995 with the single "Precious Junk," after winning a Sony Music Entertainment audition in 1993. His 2000 single "Rakuen" brought him widespread recognition, and his 2004 single "Hitomi wo Tojite," the theme song for the film Crying Out Love, in the Center of the World, became one of the best-selling singles of that year. He has continued to release music and tour through his 30th anniversary in 2024.
