Summer Night on the Banks of the Kamo River near Shijō, from an untitled series of Kyoto landscapes for an optical viewer device

Summer Night on the Banks of the Kamo River near Shijō is the companion to the Sanjūsangen archery print and is held by the Fine Arts Museums of San Francisco (Legion of Honor, 1969.36.2), also from the R.E. Lewis gift. The composition, dated circa 1765–1775 and measuring 199 by 264 mm, depicts the riverside cool-of-the-evening (yūsuzumi) entertainment scene at Shijō on the Kamo River — a Kyoto summer custom in which temporary platforms (yuka or kawadoko) were erected over the riverbed for elite diners and pleasure-seekers escaping the city's summer heat. Ōkyo's megane-e treatment renders the platforms in perspectival recession, with the riverbed extending toward a distant vanishing point and figures ranged in groups across the foreground and middle distance. The hand-applied color is restrained, dominated by greens, blues, and warm whites suggesting moonlight and lantern illumination. Like the Sanjūsangen view, the print was designed for the Owariya's nozoki-karakuri optical viewers and represents an early phase in Ōkyo's adoption of Western perspective into a Kyoto subject vocabulary. The Shijō riverside scene was an established subject in Kyoto genre painting since at least the Momoyama period, and Ōkyo's contribution applies the perspective vocabulary of European prints (transmitted through Chinese export imagery) to a thoroughly local theme.
