Japan · Japan's most-used QR payment app
Can you use PayPay without a Japanese phone number?
No.
PayPay says overseas mobile numbers can’t be used and asks for a Japanese mobile number at sign-up. A data-only eSIM has no number, and your home number isn’t accepted either.
What PayPay says
海外の携帯電話番号は利用できません。日本の携帯電話番号をご用意ください
In English: “Overseas mobile numbers cannot be used. Please have a Japanese mobile number ready.”

Gate B — Japanese number required
Is that number Japanese — and sometimes, is it a voice line?
No foreign number passes, no matter which carrier issued it — so neither a data-only eSIM nor your home number gets you in.
