The Wii is kinda stuck in the middle. The Wii doesn`t have the hardware prowess of the HD consoles but yet it`s not as cheap to develop for as the handhelds and has a smaller install base than the handhelds.
The Wii does have its jrpgs. They just don`t appear to be big named jrpgs. Compared to DS and PSP, Wii has very little. But compared to PS3 and 360, the Wii either has about the same amount or slightly less. The Wii jrpgs just appear to be more niche in general.
Monster Hunter Tri (I guess you can consider this an Action RPG)
Final Fantasy Fables: Chocobo`s Dungeon
Rune Factory: Frontier
Muramasa (Action RPG)
Sakura Wars (SRPG. PS2 version is favored though due to dual audio)
Dokapon Kingdom (also on PS2)
Shiren The Wanderer
Dragon Quest Swords
Opoona
Fragile Dreams: Farewell Ruins of The Moon
Tales of Symphonia: Dawn of the New World
Final Fantasy Crystal Chronicles: Echoes of Time
Final Fantasy Crystal Chronicles: Crystal Bearers
Baroque (also on PS2)
Valhalla Knights: Eldar Saga
Would Little King`s Story also count? It has some RPG elements apparently.
And then of course you have these upcoming jrpgs...
Dragon Quest X
Last Story
Xenoblade
Arc Rise Fantasia (in June I think. Yet another niche jrpg though)
