Requirements for apps in Japan.

Apps available in Japan need to follow certain requirements if they have a price for download or offer in-app purchases. 

Apps need to include a support link with valid contact information, as required by the App Review Guidelines. Your apps also need to display certain pieces of information (such as your seller name, address, and contact information), as required by the Act on Specified Commercial Transaction.

To view these requirements, visit the Consumer Affairs Agency's website.
