Old singles in Japan

Not trying to hook up lol, i’ve been in southern japan for a couple weeks progressively making my way to Tokyo. Im trying to find singles for old sets like Clannad, Psycho Pass, Accel world, and a bunch of others but I’ve had very little luck. Im really hoping that the closer i get the better odds i’ll have in finding them but honestly i’m not sure thats going to be the case.

Does anyone know of anywhere i can find single cards from older sets near Osaka, Hiroshima, Tokyo area? Really having a hard time here. Someones gotta have em, i just don’t know where.

Any ideas or input would be appreciated, thanks!
