"7-9PARK" aims to create a new cultural experience in Shinjuku Gyoen by fostering morning activities in public parks through the use of an app. The app facilitates various morning activities like yoga, running, breakfast, and kids' school, which appear in the park for a limited time.

The app collaborates with local businesses and trainers to offer a diverse range of morning activities. Trainers and local businesses register on the app, enabling simultaneous appearances of training sessions, yoga classes, breakfast events, and more in the park. Participation and registration are made easy through QR codes and cashless transactions, ensuring a comfortable experience. By involving the community in providing a variety of activities, including support from athletic trainers, physical therapists, body transformation specialists, and children's trainers, 7-9PARK contributes to creating a new culture of health utilizing parks.
