Where to find Japanese Books (Besides Kinokuniya)

Hey all,

I'm studying Japanese and I love going to Kinokuniya in Katy. But for the sake of variety I was wondering if there were any other spots. Or is Kinokuniya just an oasis in the desert?

I know HPB occasionally will get some in, but really I'm kind of looking for a place that has them consistently. A long shot, I know, but if anyone can find it, Reddit can.

Thanks for your help!
