record shops in Japan, Korea

I just got back from a trip to Japan and found a few good record stores in Osaka. I found some good stuff at Smile Records and another shop directly across the street.

I found a bunch of stores in Tokyo especially in Shinguku but everything was pricey. A big disapointment.

I'm going to be in Korea next week and also back to Tokyo for a few days. Any suggestions for good vinyl at reasonable prices? I'm not much interested in classical but most anything else.
