Welcome to the Komoju API documentation.
Komoju is a Japanese payment gateway which supports all major payment methods in Japan(JPY). We offer a RESTful API and a Hosted Page for easy integrations. We also offer technical support in both English and Japanese to help you get started.
In accordance with Japanese laws and regulations, merchants must be PCI DSS certified in order to store credit card numbers or are required to operate without storing card numbers. At this time, we are not able to provide you with REST API access until verifying your PCI certification status. If you do not plan to become PCI DSS certified, we recommend that you use either our Hosted page or our Multipay options. If you have any questions, please reach out to us via our contact form.
Komoju offers various ways to integrate with your platform and you can choose the best integration for your payment needs.
The purpose of the test mode is to demonstrate all the functionality the live mode provides to aid in integration with the Komoju platform. You can create an account and begin testing by signing up. Once you've created an account you can access the test mode using the following URL:
Users can apply for live mode access through their account. You will need to provide details about your company, where you plan to use Komoju, and which payment methods you would like to use. Once you have been approved we will provide you credentials for a live mode with access to live payments.
For general account enquiries, you can reach us using the Komoju contact form.
Domestic Credit Cards
Many Japanese customers run into problems and failed/blocked transactions when trying to purchase from online retailers outside of Japan.
With Komoju, we work closely with a Japanese bank to ensure Japanese credit card transactions go through and are processed correctly.
Convenience Store (Konbini)
Komoju handles delayed payment options, including Konbini, which is very popular in Japan for its security, anonymity and convenience.
Payments can be made at the following stores:

When the customer pays at the store for a convenience store purchase, they are charged a fixed processing fee which is standard in Japan.
Komoju supports various prepaid cards and online wallets. Currently our system supports BitCash, NET CASH and Webmoney. These prepaid cards can be purchased at many stores here in Japan. Prepaid cards are popular for sites relating to games, anime, manga, etc.
Bank Transfer is an electronic funds transfer between two bank accounts. This payment option is popular with customers making large payments. Customers can either remit at an ATM or via online banking to complete the payment process.
PayEasy Japan has 7.5 million registered users and is completely seperate from PayEasy international. We work closely with the PayEasy team and they regularly feature our clients in targeted promotions to their user database.
Like Convenience Store payments, the customer is charged a fixed processing fee when they pay for a PayEasy purchase.
