Rakuten Pay is an online payment service from Rakuten Payment Inc., part of the Rakuten Group. It lets businesses accept payments from Rakuten members with one-click checkout using Rakuten ID, enabling customers to earn and redeem Rakuten Points across purchases.

The service operates on a pay-as-you-go model with zero initial costs and zero monthly fees, charging only when sales occur. It integrates with the broader Rakuten ecosystem including Rakuten Ichiba marketplace and Rakuten Card, giving merchants access to the Rakuten member base and point system that drives customer loyalty.

The platform supports 3D Secure authentication for credit card transactions to verify cardholder identity and reduce fraud risks.

Merchants can accept payments through QR code scanning from the Rakuten Pay mobile app, supporting both online and physical store transactions within the Rakuten payment network.

The corporate website includes English content, though the primary service is designed for the Japanese market and Rakuten’s domestic member base.
