Reizi Sakagaki

Stage actors don't get nearly enough credit, and Reizi Sakagaki is exactly the kind of person I think about when I say that. No do-overs, no editing in post — just you, the boards, and a live audience every single night. He's a Saitama kid who went through Toyo University, stands a clean 180cm, and was born in 1995, which puts him right in that sweet spot where a performer starts to really find their depth. I don't know his full resume by heart, but honestly that almost makes it better — this is someone clearly grinding the stage circuit the quiet, unglamorous way, building something real one performance at a time. There's a particular kind of grit in that, and I respect it more than a flashy highlight reel. I'm genuinely curious to see what roles pull out something unexpected in him. The under-the-radar ones always surprise you eventually.
