I received a guarantee of authenticity for both the artwork and the box inscription at the Kyoto Kanjiro Museum. There are no cracks or chips. It is a very beautiful piece. As shown in images 8-12, the rugged, abacus-shaped foot is characteristic of Kanjiro's work. Size: Diameter: Approximately 16cm, Height: Approximately 5.5cm. Since the work is called a "bowl" (碗) and not a "plate" (鉢), I believe it is a summer tea bowl. Related to: Hiroji Kawai Toshitaka Kawai Sota Kawai
