Thanks. I noticed that I can't buy btc at bitcoin atm in Japan anymore. A few btc atm is still alive in this country but they only buy btc.
read this to understand the difference between anonymous and 'without id verification': https://99bitcoins.com/buy-bitcoin/anonymously-without-id/
nice kyc-free overview here: https://kycnot.me
note that some listed exchanges are only supported in specific countries/continents (e.g. Peach Europe) or with specific currencies (Relai - eu, ch)
Discussion
if you want to sell you should reconsider not doing that lolol
but if you want def. bisq, robosats
im sure they're nices (maybe centralised, yet p2p and kyc-free) escrow apps in your region to sell on if the demand for btc is low through bisq or robosats
i dont have japanese ppl in my current network unfortunately (at least that i know of)
