Very good suggestions I will enphasize in some:
Fragile Dreams: Farewell Ruins of the Moon
Muramasa the Demon Blade
Sakura Wars
Fire Emblem
Rune Factory
Monster Hunter Tri
Phantom Brave (unless you already have the PS2 version)
Arc Rise Fantasia
Those are all very Japanese, very RPG like games (with some action-rpg and strategy-rpg between them). Outside that scope I'll also recommend:
Silent Hill: Shattered Memories
Little King's Story
No More Heroes 1 & 2
Trauma Team
Great games, and different enough for you to try them, there are a lot more, but I think with those it should be enough to at least tease you.
