About NTT Docomo in Japan
NTT Docomo is one of the 5 prepaid networks operating in Japan, with the dial code +81. Refills are denominated in JPY and settle on the carrier under 60 seconds after our payment confirms on chain.
You don't need a NTT Docomo account, the Japan MyCarrier app, a local bank or any in-store kiosk — just the phone number and the crypto. The credit shows up on the SIM exactly the same way as if you'd topped it up at a corner store.
NTT Docomo mobile top-up · FAQ
Can I top up NTT Docomo with Bitcoin?
Yes. Pay in Bitcoin (BTC), Monero (XMR), Ethereum (ETH), USDT (TRC/ERC/SOL), Litecoin (LTC), Bitcoin Cash (BCH), Solana (SOL), Dogecoin (DOGE), Dash (DASH), Tron (TRX) or BNB. The NTT Docomo line in Japan gets credited within minutes of your deposit confirming on chain.
How fast does the NTT Docomo credit land?
Carrier-side, NTT Docomo typically posts the credit within 30 seconds of our settlement message. End-to-end (you click pay → SIM has credit) it's usually 1-3 minutes on fast chains (LTC, TRX, SOL), up to 10 minutes on slower ones (BTC).
What's the cheapest crypto for a NTT Docomo refill?
For small refills (under $50 USD-equivalent), USDT-TRC20, Tron (TRX), Litecoin (LTC) or Solana (SOL) keep network fees to single cents. Bitcoin works fine but BTC fees can be disproportionate for small top-ups — pick a cheaper chain instead.
Do I need a NTT Docomo or Japan account?
No. We talk to NTT Docomo on the back end with the phone number alone. No MyNTT Docomo portal login, no SIM swap, no local bank, no in-store kiosk. Just enter the number, pick the amount, pay in crypto.
Will NTT Docomo or the recipient see I paid in crypto?
No. NTT Docomo sees a routine top-up at the local face value (JPY). The recipient sees the new balance on their SIM. Neither sees the funding source, your email, or any other payment metadata. From the SIM's side it's identical to a corner-store refill.
