Kai-awase (Shell Matching)

Kai-awase (Shell Matching), painted about 1915 and held by the Mizuno Museum in Nagano, depicts a group of Heian-style aristocratic women absorbed in the classical court game of kai-awase, a shell-matching pastime in which players paired the two halves of bivalve shells, each painted on the inside with a poem or a scene. The game carried strong associations of refinement, literary learning, and conjugal harmony — the matched pair of shells served as a symbol of fidelity and was a traditional element of bridal trousseaux — and it had been a frequent subject of Japanese painting since the late Heian period. Ikeda Shōen's treatment, executed in ink and color on silk in the formal screen format, draws on her training under Mizuno Toshikata (1866-1908) in the close observation of costume, deportment, and seasonal accessory, while applying the soft graded washes and brush-trained line of late-Meiji and Taishō nihonga rather than the heavier polychromy of earlier court-genre painting. The screen belongs to the historicizing strain of Taishō [bijin-ga](/glossary/bijin-ga) in which artists revived Heian and Edo subjects as exercises in costume study and as occasions for reflection on Japanese feminine cultural tradition. The Mizuno Museum's screen is one of the artist's most ambitious surviving large-scale works and a key document of her engagement with the classical court genre.
