Mizusashi are jars used to hold water for the preparation of tea at tea gatherings. This one was produced in the Mino area of present-day Gifu Prefecture in central Japan. It is called a “picture Shino” (e-shino) mizusashi, as it has an abstracted design on one side, said to resemble an ink painting of reeds and small boats along a riverbank, and a geometric pattern on the other. With its irregular shape and thick, luminous glaze, it is of a variety favored by eminent tea masters of the Momoyama period.
