The concept design of the “Glass Tea House - KOU-AN” was presented at the Glasstress 2011, the collateral event of
the 54th La Biennale di Venezia. In 2015, the teahouse was first unveiled at the stage of Seiryu-den which is in a precinct of Tendai Sect Shoren-in, Kyoto, and was in the limelight worldwide.

Japanese concept of nature, which perceive energies, is embedded in the culture of tea ceremony. 
“Glass Tea House - KOU-AN” is not merely a modernized tea house, but an art project that traces the origin of Japanese culture. 

This glass-made architecture of light does not have a scroll nor flower that are supposed to be provided in traditional tea house.
Instead, the floor is dressed with sparkle reminiscent of water ripples, and reflections of sunlight within a prism project a rainbow.
Integrated with nature and released from materialistic concept, this architecture of light illuminates poetic scenes.
