Ippitsu gafu

Ippitsu gafu, whose title translates roughly as A Sketchbook of One-Stroke Drawings, is a printed book by Katsushika Hokusai that gathers figures, animals, plants, and landscape vignettes executed with the principle that each subject can be reduced to a single calligraphic stroke or a small number of bold lines. The book exemplifies Hokusai's lifelong interest in teaching the principles of efficient drawing, and it sits alongside Hokusai manga, Hokusai gafu, and Gadō hitori keiko within the artist's pedagogical book program. Each opening displays a series of brushed forms in which the underlying logic of the stroke becomes the subject as much as the figure being drawn. As an Edo ukiyo-e production, Ippitsu gafu also documents the high level of refinement Edo woodblock carvers could bring to capturing the subtle weight and direction of a single ink line. The Art Institute of Chicago copy preserves the spare keyblock impression that allows readers to study Hokusai's draftsmanship without the distractions of polychrome printing. The book demonstrates how Katsushika Hokusai understood the ukiyo-e print as a vehicle for transmitting technique, not only narrative or genre, and shows the philosophical streak in his late practice in which economy of means signaled mastery rather than haste. For students of Japanese drawing and for collectors of his books, Ippitsu gafu remains a foundational document, frequently invoked to explain how Hokusai's bravura single-line virtuosity underlies even his most elaborate polychrome compositions, and continues to be studied by artists interested in the relationship between brushstroke and figure.
