Yanagi-san is a very interesting artist. Born in Fukuoka, studied as an artist and worked as an artist in residence all over America, he has a global perspective and insight that he brings to his craft. He is also hugely prolific and active in the production of art. Many of his pieces are large in scale, and he has taken his artwork from the place of the studio to larger geographic canvasses.
In terms of his impact on the Setouchi Triennale, he has transformed the island of Inujima into a complete art piece. The project is called Inujima Seirensho Art Museum. In this, Yanagi-san has taken the ruins of a copper factory and turned it into an art space. In addition, the entire facility is environmentally sound and friendly. Solar power, and geothermal energy is used. A sophisticated water purification system is also installed. The architectural structures are modelled on Yukio Mishima’s home.
But Yanagi-san is not without some controversy. In his work involving ants he brought upon himself the ire of PETA. You can read about that here: https://www.sartle.com/artist/yukinori-yanagi
