Second-hand violin in Tokyo

Hey! I have a quick question. I’m currently in Tokyo and looking to buy a a second-hand violin. I’ve done some research and found places like 2nd Street, Hard-Off and Book-off which have a pretty good selection of used instruments. Some people also said it might be cheaper or easier to get one from Mercari or Amazon.
For those who’ve bought instruments here before, what’s your experience and what would you recommend?
Thank you!
