A permanent exhibition of about 350 pieces of sculpture. The green of the prairie and the blue of the sky are abstracted on the canvas, scattered with a variety of figurines. Takeyoshi Inoue's "My Sky Hall (a box that looks into the heavens)", Susumu Niinomiya's "Compass of the Stars", Cesar's "Thumb", and Rusiminbourg's "Sparrow @ Utsunitai Hoomodus", etc. It is characterized by many individual and large scale works by contemporary writers from Japan and abroad. From spring to autumn, dainty plant flowers such as hakusanfuuro, willow orchids and pine-eel compete in bloom, with the area serving as a treasure trove of alpine plants. You can enjoy a 360-degree view of the surroundings and beautiful flowers along with the sculptural works.
