Features and experience value

A "Genkiro" that turns everything into positive.
The Oya Genkiro No. 6, which resembles a giant tree standing tall in an underground space, is an experiential art installation. Water is boiled in a large kiln containing medicinal herbs, and the steam is sent in through a pipe.

Visitors can enter the work and experience something like a steam sauna. It is a new experience that will leave you in good spirits and body. Inside the work, the steam makes it impossible to see even a meter ahead, and the scent of herbs and medicinal plants and the dense steam will awaken all your senses, allowing you to enjoy a new world.
