I NEED more Uketsu books!

I recently read Strange Pictures and Strange Houses both by the elusive Japanese writer/artist Uketsu (they're more thriller/mystery than horror but that wasn't an option for flair). To my knowledge, Uketsu does not have any other books currently aside from a couple of other comic/manga style ones. I loved both SP and SH and want another book like them immediately. Even better if it's by another Japanese author (I was in a Japanese immersion program from K-12, speak the language fluently, love Japan, and have been extremely immersed in the culture my whole life) but I'll take any author of any background if they have similar books.
