Greenia has undergone a major evolution in preparation for the opening of the 2026 season!
Rokko Mountain Obstacle Park GREENIA, Japan's largest* outdoor Obstacle facility, will open a new area for preschoolers called Chibidoland on Friday, March 20, 2026 (national holiday). The track and field Obstacle area, yahhoy, will also be reopened on the same day, under the supervision of popular video creators Fishers.
1. Chibidoland: An area exclusively for preschool children
This is a special area where small children can safely enjoy Obstacle debut.
- Safe artificial turf throughout: The entire area is covered with artificial turf so that small children can move around freely.
- A total of 12 Obstacle points: We have prepared a variety of activities for preschool children to try.
- Resting hut for guardians: A hut with shade is provided. Parents can take a rest while keeping an eye on their children.
- Official character: "Chibidora", the child of "GREENIA DRAGON", has been born, aiming to become a legendary dragon.
2. Renewal of the Obstacle "yahhoy"
It will evolve into an area where everyone from elementary school students to adults can enjoy themselves more safely and actively.
- Introducing 4 new Obstacle points: 4 new points will be added where you can take on new challenges.
- Separation of traffic flow by generation: By consolidating the areas for preschool children into a new area, people of all ages can now enjoy the park more safely.
Fishers Supervisory Comments
Greenia is celebrating its 5th anniversary. We are excited to be able to create new Obstacle again. We will be creating Obstacle area for preschoolers, which has never been seen before, so we hope that many children will make Obstacle debut. In addition, the popular Yah-hoi area will be renovated to include content that can be enjoyed by children and adults alike, so we hope that many people will come and experience it!
