I do not know about that, it is surprising that you can not buy bitcoin from Japan on binance, but you can try other exchanges which I am sure you can use to buy bitcoin directly from Japan, you can use kraken, gemini, bitflyer, localbitcoin, or coinmama for the purchase. You can read more about this on
https://www.buybitcoinworldwide.com/japan/.
You can also use bitfinex but they have low reputation after it was hacked in 2016, 120,000 btc was stolen from the exchange.
@OP says he's looking to use a CC.
- Kraken doesn't have credit cards options (
it uses Etana custody for JPY)
He also says to be from Japan
- Gemini doesn't accept Japan citizens as per
the FAQ@benjd247, take a look at Coinama, Coingate, Paybis, and Bitstamp
perhaps but I don't know if the option is available with JPY
