Tokyo shops? Cartridges and vinyl gear


Hi! Thoughts on where to find a hifi shop in Tokyo that sells cartridges? Looking to find non export audio technica styli/cartridges. Specially an at7v stylus, but also interested in any unique finds or bargains one can get in Japan. Also/or onzow stylus cleaners? I know they are more available here now but always understood them to be cheaper over there.
