Attributed to second generation Tadamasa Shōzaemon (died in in the fifth year of Enppo, 1677). Early Edo period: 17th century (Kan-ei / Kanbun era). Height: 79.0 mm. Width: 77.5 mm.

Symbols of Japan. Thematic motifs in art and design. Rizzoli international publications, Inc., 2001], "a bamboo grove is said to be emblematic of security as the bamboo is resilient even in the face of high winds and heavy rains. [...]  The association of the sparrow (suzume) with bamboo is an old one found in Japanese poetry, paining, and design. The bird is said to be obsessed with its honor, especially the repaying of debts".
