The f-JOY app is a lifestyle shopping application developed by FJ. Entertainment Works Ltd. It allows users to accumulate points while shopping at participating facilities in Fukuoka's commercial facilities Canal City Hakata, Marinoa City Fukuoka, and Konoha Mall Hashimoto. The accumulated points can be used as equivalent to 500 yen in units of 500 points.

The app provides valuable information about various campaigns, sales, and events of interest. It also offers great coupons and discounts at shops and restaurants, including free drinks and ice cream. Users can easily check the shop list, events, news, and facility information of their favorite facilities in the app. By switching the facility name, users can also check facility information other than their favorite facilities.

Please note that the app uses GPS by default to deliver relevant notifications and coupons based on highly accurate location information. In order to use this application, it is necessary to enable GPS settings. However, users can change to a setting that consumes less battery (not using GPS) at any time from the setting screen of the terminal.

Overall, the f-JOY app is a convenient and economical way to connect with joy while shopping in Fukuoka's commercial facilities.
