Biography
Little is known directly about his life; he is believed to have been born in the village of Tamba,[2] near Tachikui in Hyogo Prefecture, near Kobe.
He is associated with Kyō ware, often being credited as one of the key founders and influencers.[3] He was a master craftsman who perfected the colourful painted pottery in Kyoto. After learning the technique of making tea jars in Seto, around the Shōhō era (1644-1648) he opened the Omuro kiln in front of the gate of Ninnaji Temple.[4] Tea master Kanamori Sowa (Shigechika) heaped high praise for his excellent potter's wheel technology and Kyoto-style design.[5] In response to orders from the public and daimyō families his ware became popular with Japanese tea ceremony.

He is also believed to have had a son, nicknamed "Ninsei II", who attempted to succeed him in his work, but did not reach the same level.[6]
