There are some good Japanese RPG games that have been either fully translated or at least partially translated (interface translation) that might suit your tastes. A few that I can remember off the top of my head are: Rance (series of games), Kami no Rhapsody, Ikusa Megami (series of games), Beat Blades Haruka, Eiyuu Senki, Dungeon Of Regalia, Bunny Black 1 & 2, Seinarukana -The Spirit of Eternity Sword 2, Lightning Warrior Raidy (series of games), Madou Koukaku, Himegari Dungeon Meister, Gears of Dragoon 1 & 2 (first one was a fantastic dungeon crawler game-play wise (didn't play the second one), interface translation is all there is though, but you don't need to know the story to enjoy the game-play).
Other games I remember, are Sakura Dungeon and Dungeon Master Chris. Both have pretty art and decent dungeon crawler game-play.
Out of all of those, the Ikusa Megami series and the Gears of Dragoon series are pretty fantastic. Some of the Rance games are good too game-play wise, if you can deal with that kind of protagonist. Bunny Black series and Eiyuu Senki are decent, as well. Actually, I have found some good things and bad things about all of those games mentioned above, but that's for you to decide.
You could look most of those up on vndb dot org (read summary/genre decriptions and view screenshots) and find some game-play clips on youtube to see if you are interested before bothering to download. I hope you find something you like.
