Determined to keep her collection moving with the times, the MFA’s energetic head curator of Japanese art, Anne Nishimura Morse, is trying to cultivate new and younger collectors. And she is always looking out for opportunities to show Japanese contemporary art. “Fired Earth, Woven Bamboo: Contemporary Japanese Ceramics and Bamboo Art” is one fruit of these efforts. It is a smart, visually appealing display of 60 three-dimensional objects — ceramics and baskets, although not as you might think of those categories — from a collection of more than 90 works recently given to the museum by the collectors Stanley and Mary Ann Snider.
