The Hiroshima JP Building PASS app is designed for iPhone users, providing a seamless experience for accessing buildings managed by Japan Post Real Estate. Its primary feature is the smart entry system, which utilizes Bluetooth technology for one-touch access, allowing users to enter buildings effortlessly. The app enhances convenience by ensuring users can quickly enter their workplaces without the need for physical keys or cards.

In addition to access management, the app keeps users informed with updates from building management and affiliated tenants. Users can view various events and news, as well as important announcements, including a history of notifications for easy access to past updates. However, users should be aware that Bluetooth strength may affect functionality, and some services may be temporarily unavailable depending on the time or situation.
