Great Prosperity at the Silk Farm (Kaikoya Daihanjono Zu)

This circa 1837 large ōban [triptych](/glossary/triptych) by Utagawa Kunisato, held by the Art Institute of Chicago (accession 1939.2275, with two additional impressions accessioned 1925.2316 and 1925.2317), depicts a panoramic scene titled Kaikoya Daihanjono Zu (Great Prosperity at the Silk Farm). The composition documents the silk-rearing industry that was a major source of household-level income in late-Edo and early-Meiji rural Japan, showing women workers tending mulberry-fed silkworms across the three-sheet panorama in a documentary mode that the late-Tenpō Edo print market increasingly demanded alongside the standard theatrical and warrior genres. The dating of c. 1837 places the print at the very beginning of Kunisato's documented career, within the Tenpō reform era when censorship pressures were beginning to constrain the actor- and courtesan-print genres and to push Edo print designers toward documentary, geographical, and current-events subjects that fell outside the reformers' scrutiny. The triptych format allowed publishers to sell the composition as a single luxury piece while making each sheet saleable on its own, a marketing strategy that the Edo publishers used heavily for panoramic compositions of this type. The print is preserved in three separate impressions at the Art Institute of Chicago, all in the Clarence Buckingham Collection or related Japanese print holdings, and the AIC's open-access program has made high-resolution IIIF imagery of all three impressions available for comparative study, an unusually rich documentation for a single Kunisato design and one of the most accessible primary sources for this artist's early Tenpō-era work.
