Second-hand record stores in Tokyo

Japanese city funk jazz is to die for indeed. Look also for vintage anime soundtracks with that badass funky jazz there. IM me for titles

You can make money when you get back with those records.

Disc Union, near the Ochanomizu train station, which is one stop away from Akihabara station, has a vast selection of both new and used LPs.  They rate their used LPs on an A, B, C scale.  You can buy A and even most B rated LPs sight unseen with full confidence that they will play as if new.

@lewm , Japanese vinyl grading system is similar to Russian system of grading records. In Soviet Union collectors would only have 2 ratings Mint or Not Mint where Mint means it's good to sell which means there's not even a fingerprint can be noted.
