Why SOL works for hosting in Japan
Solana settles in seconds for a fraction of a cent, the cheapest way to clear an invoice from a phone wallet. In Japan the alternative is a card billed in dollars against a Japanese yen (JPY) balance. Most local cards are billed in JPY, so a dollar invoice may carry a foreign-transaction or conversion fee — that part is set by the bank, not by us.
Paying from a wallet takes the bank out of the transaction. The invoice is priced in US dollars, the SOL amount is locked for 15 minutes at the live rate, and the transfer goes straight to the address on the invoice. Nothing to approve, no merchant category to argue about.
