Temples have existed in various parts of Japan since ancient times. Temples are places where Buddhist statues are enshrined, ordained Buddhists reside. They have unique architectural spaces. The cloister, one of the representative spaces of temple architecture, expresses the boundary structure between the sacred and the secular and protects what is inside by enclosing it. In addition, temples are places where anyone can come and go. They are the center of local communities. That is where culture and tradition are born and passed on. Temples have the power to protect and pass on what is in the corridor. In the lake in the west, which is the subject site, there is a beautiful waterfront landscape with reeds growing thickly. Since ancient times, reeds have been associated with people's lives in various ways, such as food, roofs, and torches for fire festivals. The annual cutting of reeds and lighting of reed fields is a traditional event in early spring. That has helped preserve the beautiful scenery of the reed fields. However, nowadays, the reeds and people's lives are becoming separated. Therefore, the reed landscape is lost. Therefore, this project aims to preserve the reed culture and landscape by enclosing the reed life in the temple.
