Chōjū ryakugashiki

Choju ryakugashiki (Abbreviated Pictures of Birds and Animals), a woodblock-printed book of 1797 held by the Art Institute of Chicago, is one of the foundational volumes in Kitao Masayoshi's celebrated ryakugashiki series. The title - choju meaning "birds and beasts," ryakuga meaning "abbreviated picture," shiki indicating a treatise or method - announces both subject and approach: an encyclopedic survey of the animal world rendered in deliberately reduced, calligraphic line. Masayoshi presents creatures of land, air, and water with the economy of a master brush draftsman, capturing essential posture and character in a few decisive strokes. The volume distills the Kitao school's commitment to careful observation and turns it toward pedagogical and aesthetic ends, providing both a sourcebook for other artists and a stand-alone pleasure for the connoisseur reader. The book belongs to the larger group of ryakugashiki publications (also including the volumes on people, landscapes, fish, and plants) that together constitute one of the most influential pictorial projects of the late Edo period. Modern scholarship credits these albums with shaping the visual culture from which Hokusai's Manga and many subsequent Japanese sketch-album traditions would emerge. The Art Institute of Chicago's holding is a key reference copy for any serious study of Edo zoological illustration and the development of Japanese pictorial shorthand.
