The Unkonshi was named after the phrase "cluds are generated from rocks". It contains information on habitat, history and features of over 2000 tyoes of unique rocks and stone tools, fossils and minerals which were collected by Sekitei Kiuchi during his lifetime. Born in 1724, Kiuchi worked with the local magistrate of the Zeze domain until he retired in his 20's. He studied honzogaku with Keian Tsushima in Kyoto, and became one the central figures in the Kansai cultural salon of that time. He actively attended exhibits throughout the country including Kyoto to collect specimens and gather information.
