Like a Dragon (Yakuza 7) is the only Yakuza game, to date, that’s a JRPG. At least in the way most people think of JRPG (turn based combat).
They’re all great games, just wanted to point out that only the one, so far, is a turn-based JRPG.
I think it would probably make for a great first JRPG experience. Persona 5 is pretty accessible, but it’s very anime and tropey. That said, I’m not a fan of anime and absolutely loved the game. Either would be a great starting point.
