"Raden Togaku" is a collaborative unit formed by 小島紗和子 (chogoro), a wood lacquer and mother-of-pearl inlay artist from Tanba City, Hyogo Prefecture, and 山口和声 (やまぽた), a ceramic artist from Ise City, Mie Prefecture. 小島紗和子 learned mother-of-pearl inlay techniques from 小島雄四郎, a disciple of Living National Treasure 黒田辰秋, and has had works accepted into the Kokuten exhibition. 山口和声 trained at Iwai-gama kiln in Tottori, then established a studio in Ise City rooted in the mingei spirit, winning the Kokuten Newcomer Award. Together they create framed artworks that fuse ceramic and mother-of-pearl craftsmanship.
