Raku (comfort, ease) bowls were considered some of the most valued tea-ceremony vessels throughout Japan during the 16th and 17th century. Originally created by 16-century tea master Sen Rikyu and tile master Chojiro, the bowls, usually made from red or black clay and hand molded, were passed down through generations. They became symbolically influential throughout Japan's history of culture and literature.

This exhibition showcases more than 100 raku works that have been donated by the Mitsui family, as well as pieces from the Kishu Tokugawa family. Also on display is Maruyama Okyo's 1773 painting "Pine Trees in Snow," a designated National Treasure of Japan; Dec. 4-Jan. 25.
