It is the largest wooden structure in the world. It was built from 10,000 tons of wood.

The team was led by renowned Japanese architect Sou Fujimoto. He has designed buildings such as the House of Music museum in Budapest , a tourist building located on the grounds of the Ruinart champagne house vineyard in Reims, and a futuristic public toilet in Tokyo, which appeared in Wim Wenders' acclaimed 2023 film Perfect Days.

The modular circle consists of segments that are joined together using both modern methods and the traditional Japanese "nuki" technology. This method of joining wooden elements was used, among other things, in the construction of Japanese temples and shrines.
