According to Asian calligraphic traditions, there are "four treasures of the study": the brush, ink, paper and inkstone. Just as crucial, however, is the humble water dropper, which was used to wet inkstones for use.

During the Joseon Dynasty (1392-1910), calligraphy in Japan was an art form of the ruling class and the literati, and the decorative water dropper became a popular writing accessory, available in a plethora of shapes and sizes, and often inscribed or decorated with literati ideals or motifs. This exhibition brings together 126 water droppers from The Museum of Oriental Ceramics, Osaka's collection, revealing not only the diversity of the vessels, but also the growing influence of Korean ceramics in Japan. This is the first time since such an exhibition has been held since 1988.
