@lewm all good man, you are right the one on akihabara is not that good I visit that too but the one I recommend is on Yurakucho, that one is very centric very close to Gynza. I bought so many good things there and a lot that I could not buy because the power is 100 V
@sammyshaps I just listen digital I am not into vinyl but I am sure you can find anything in Tokyo from what I saw.
