Some of the popular crypto ATM providers in Japan include BitOcean, BTCBOX, and Coincheck. Here is a simple instruction on how to buy BTC from a crypto ATM in “the Flowery Kingdom:”
Find a Bitcoin ATM near you. You can do this by checking online or using a Bitcoin ATM locator app.
Once you have found a Bitcoin ATM, you'll need to ensure that you have a Bitcoin wallet installed on your smartphone or laptop, which will enable you to receive the digital currency.
Then, go to the Bitcoin ATM and select the "Buy Bitcoin" option. You'll be asked to enter the amount of Bitcoin you want to purchase and the ATM will scan the QR code of your address wallet.
Deposit cash or insert the debit card, depending on the features of a given machine.
Review and complete the transaction if you agree on the offered exchange rate (fiat-to-crypto).
The purchased Bitcoin will be transferred to your crypto wallet, becoming yours for whatever use.
Unfortunately there are no more bitcoin ATMs in Japan since around 2019.
So where ever you copied this from, it's old.
