I haven’t seen too many Japanese LPers who use face cam. I’ve seen the few that do sometimes wear face masks which is tough from a learning standpoint as it muffles their words/hides their mouth.
However I did find this guy who sometimes has face cam. (He tends to play a lot of Japanese games.)
There’s also SeikinGames. He plays a lot of Minecraft/Nintendo games.
2bro is great because I prefer LPs with two+ people bantering. (I also really like them because they play a lot of western games that I’ve already played so I can concentrate on their speech instead of the game.)
Also if you want to find a specific Let’s Play on Youtube, use “実況プレイ” or “実況” plus the game title.
