KATAKISHI is a “material store” formed in Tokyo in 2017 by Arawatari Iwao, Unno Rintaro, and Takamisawa Shunsuke. The number of participating artists changes for each project, but in 2019, Takahashi Pig iron will leave the store, and as of 2023, the core group consists of nine members including Tanaka Kantaro, Oyama Hiho, Shishikura Shinobu, Suzuki Yudai, Oka Chiho, and Mizushima Yume. With being a “store” at its core, it is attempting to establish a unique survival strategy that does not depend on the existing economic system of the art scene.
