crowdfunding since October 2024 with the aim of becoming a
“one-of-a-kind excavation type theme park” where you can experience excavation in the Oya stone cave. Thanks to your support, we were able to reach our goal amount. After that, a new excavation-type activity was completed during the approximately three-month closure period. It is scheduled to reopen after renovations in March 2025.
