The design creates an art space in a cherry blossoms valley based on the philosophical concept that time and space are endless with an open attitude. The design uses steel as the only material to establish a wonderful connection between man and nature. Breaking the limitations of traditional theater stage boundaries, all performances interact freely with the audiences and visitors. Nature also becomes the main charater in an artistic way. The designer has closely cooperated with the craftsmanship workers to weave the wonderful semi-dome structure by hand in the woods.
