岡山県立美術館
A large museum housing approximately 2,000 works by famous artists throughout Okayama Prefecture. The museum's permanent exhibition features art dating back as far as the Muromachi Period (1336-1573), such as work by the priest Sesshu and the swordsman Musashi Miyamoto, as well as Bizen pottery and works by more contemporary artists.
岡山市立オリエント美術館
An interesting museum of Middle Eastern art. The special exhibit details art and trade between China and Persia. If you can speak conversational Japanese, talk with the friendly docents; they will present some highly interesting explanations and background. However, the dates and areas are clearly marked, and the artifacts themselves are interesting enough that you don't need to have a guide to enjoy them.
