倉敷考古館
Housed in a particularly lovely old rice warehouse, this museum has Japanese, Chinese, and even Incan artifacts on display.
大原美術館 Ōhara bijutsukan
The first museum of Western art in Japan,it houses a deservedly renowned collection of classic European and American art, including major works by Picasso, Renoir, Monet, Matisse, and many others. There's another building for exhibitions by modern Japanese artists, which tend to be very good. Set aside some time to wander the grounds as well, with Rodin statues out front, a small sculpture garden out back, and neoclassical columns beatifically out of character with the rest of the area.
大橋家住宅
If you've had it with ordinary merchants, visit the home of this family of retired samurai who went into business in Kurashiki.
いがらしゆみこ美術館
Memorabilia and artwork from Candy Candy, one of the most popular manga among Japanese girls and a cult favorite overseas. (There is, however, no actual candy here.).
児島虎次郎記念館
Dedicated to the work of the Japanese artist who directed the acquisition of most of the Ohara Museum's collection.
倉敷民藝館
Hosts excellent seasonal and permanent exhibitions of Japanese folk crafts. Even if you're not captivated by the subject matter, the space in which it's housed — three vintage structures connected by narrow corridors and old stairwells — is worth checking out.
