Three sections of a customarily eight-section bridge are placed above some iris. The harmony between the straight lines of the bridge and the fluid curves of the iris is very beautiful. The design is gorgeous and compact. This is an early piece of Akasaka tsuba with purplish black. Compared to other Yatsuhashi Akasaka pieces, this shows much elegant beauty and old age. 74mm X 72mm diameter, 5mm thickness.
