Downloading a remittance certificate onto your device from the Smiles app is free.
If you request a hard copy from us, it will be free for the first request, but it will cost 500 yen for the second request.
You can request for a remittance certification a few months before the year ends.
When you're filing your taxes in Japan, you will need to present a remittance certification as one of the documents you need to submit.
