I inherited this from my grandmother, who was a master of the Omotesenke school of tea ceremony. "Sohan Nagata" (1870-1948) was awarded the Menkyo Kaiden (license of full transmission) from Sosei Sōsa of the Omotesenke school and built Fushin-an in Hiroshima, becoming a prominent tea master of the Omotesenke school. My grandmother was said to be Sohan's top disciple, and she received a tea bowl with a bellflower design painted by Sohan himself. It is old Miyajima ware, dating back over 150 years. A paulownia wood box with a suitable drawstring bag has been custom-made for this item. Dimensions (approx.): Tea bowl: Diameter 13.0cm, Height 8.2cm Box: 16.0 x 16.0 x 12.5cm Unused, with no noticeable scratches or stains from aging, and in good condition. Please examine the photos and understand that this is an antique item.
