A bamboo kiseruzutsu of muso zutsu form, etched with a design of sparrows perched on a branch of wisteria. Four of the birds are huddled together, while a fifth stands watch below. Tendrils and leaves hang above them. The artist has recreated the sense of an ink painting with skilful variations of cut and graduations of knife depth.
