Made by Yoshimi Asami. I believe this is a tea bowl made to commemorate the 400th anniversary of the birth of Sen no Rikyu. The history of Sen no Rikyu is written on it. The tea bowl is in beautiful condition. Diameter: Approximately 12cm Height: Approximately 8cm The wooden box has some scratches and stains. There is no shiori (explanatory note). We look forward to your purchase if you understand the above. Thank you for viewing.
