[PC?][199X?] Weird Japanese Horror/Dungeon Crawler...

Okay this is a weird one... I don't think it was a game that was ever translated to english. I never played it myself, but I watched/read a let's play of it probably 10-15 years ago.

It was a 90's dungeon crawler in the style of like "Eye of the Beholder", it was definitely suppsed to be scary, and the subject matter was like Japanese Folktales. You wandered around a castle and encountered monsters.
