"Aogai-iri Robuchi, made by Sokou" likely refers to a robuchi (hearth frame) crafted by a lacquer artist, decorated with aogai (mother-of-pearl inlay, also known as raden). Robuchi made by Suisho Yamamoto in Mie Prefecture sometimes feature Iji-Iji lacquer or mother-of-pearl inlay. "Sokou" may refer to a specific artist or the specifications of the work. Additionally, the bottom of the accompanying box includes the date of completion: November 15, 1979 (Showa 54), as noted in the Asahi Shimbun. 【Condition】 The surface of the robuchi is clean and without scratches. However, as this is a used item, there are small scratches on the underside (photos 17, 18, and 19) and a slight wobble. The accompanying box shows signs of aging and soiling.
