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)
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.
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)
nicer
