Chopping Rice Cakes, illustration for The Board-Roof Shell (Itayagai), from the series "A Matching Game with Genroku-period Poem Shells (Genroku kasen kai awase)"

Chopping Rice Cakes, illustration for The Board-Roof Shell (Itayagai), is a Katsushika Hokusai ukiyo-e print from the series A Matching Game with Genroku-period Poem Shells (Genroku kasen kai awase), dated about 1816 and held in the Art Institute of Chicago. The series matches a classical waka poem with a finely printed surimono image, drawing on the courtly shell-matching games (kai-awase) of the Heian aristocracy. Hokusai's design shows the homely labor of pounding and shaping mochi rice cakes, a domestic activity associated with New Year's preparations, transposed into the elegant register of poetry exchange. Figures lean over wooden boards and mallets, their gestures observed with the keen attention to everyday movement that defines Hokusai's mature manner. The choice of subject quietly evokes the board-roof shell named in the poem, with the wooden chopping surface echoing the shell's pattern. As an Edo ukiyo-e print, this surimono was commissioned privately by a poetry circle and printed in small numbers using metallic pigments, embossing, and careful color registration unavailable in commercial editions. Such surimono offered Hokusai a laboratory for refined effects that would inform later projects. The Art Institute of Chicago preserves this ukiyo-e print as part of its substantial surimono holdings, documenting the integration of waka poetry, seasonal imagery, and domestic observation that flourished in Edo cultural life during the 1810s.
