Isamu Noguchi "Octetora"
American sculptor Isamu Noguchi created numerous play sculptures to bring art into the everyday playground and give children dreams.

Octetra is the best known of his place sculptures. Named "Octetra" from the Greek 8 = octo and 4 = tetra, it is an octahedral sculpture with four hexagonal faces and four triangular faces that visitors can climb inside and climb through.

Shigeo Matsubara, "Cosmic Color Space,"
Matsubara says, "By juxtaposing objects, space is connected, and an ordered cosmic space is created by merging with the nature outdoors. In this work, squares of the same size are arranged in a row and painted in a rainbow of colors: red, yellow, green, and blue. 12 different colors create a rhythm and harmony, creating a microcosm of color that seems as if it could be heard. The open space created by the series of square frames seems to draw the viewer unintentionally into the work.

This work, which makes not only children but also adults want to pass through the frames, serves as an environmental sculpture that soothes people's feelings, and also as a playground sculpture that transcends the artist's intent.

Akinori Matsumoto "Music of the Wind"
When the wind blows, you can hear a simple clanging sound coming from far above your head. When you look up, you see many pipes swaying in the wind, standing side by side with the surrounding grove of trees. The sound produced by the wind is the rhythm of nature. The pipes, made of aluminum and varying in length, create music with highs and lows in sound. For example, in light winds, they produce a gentle music like the whisper of the wind. I am self-taught in art and music.

I love music. But I can't play a conventional instrument such as piano or guitar. I have been studying the performing arts of ethnic minorities in seven Asian countries for a year and a half since 1992.
In recent years, he has been creating sound objects made of bamboo and presenting them in shadow puppet-style sound installations inspired by Asian performing arts.
