PayPay supports QR code payments at most convenience stores such as 7-Eleven, FamilyMart, Lawson, as well as at major supermarkets such as AEON, Don Quijote, and thousands of restaurants and cafes across Japan. Payment takes just a few seconds by scanning the QR code or having the staff scan the code on your phone.
Lots of cashback offers
PayPay is famous for its attractive promotions and cashback programs. The application regularly organizes cashback campaigns from 0.5% to 20% for payment transactions.
Popular incentive programs include:
- PayPay Jumbo: Chance to win 100% cashback on transaction value
- PayPay Step: Increase cashback rate based on usage and monthly payment amount
- Special promotions at major chains such as Uniqlo, McDonald's, Starbucks
- Cashback on electricity, water, gas bills
These offers not only save money but also make for a more enjoyable shopping experience, making learning how to sign up for PayPay a must for anyone living in Japan.

Easy to link to bank account
PayPay supports direct links with many banks in Japan such as Japan Post Bank, MUFG, Mizuho, Rakuten, etc. This makes it easy for you to top up, transfer money or control spending right on the app without having to open a separate banking app.
The Auto Charge feature allows you to automatically top up your PayPay when your balance is low, ensuring you always have enough money to pay without worrying about running out of money mid-way. You can also link your credit card to pay directly or top up your PayPay wallet.
