This belonged to my grandmother, who was a tea ceremony teacher. I believe it's from the Showa 20s to 30s (1945-1964). Natsume (tea caddy), small, approx. 6 x 6 cm, some staining Kouaka (tea bowl), approx. 7.7 x 5 cm, lid has a scratch I don't have any knowledge of the tea ceremony, so I don't know the details. Please understand. I am not accepting price negotiations.
