Opened in 2007, this museum of Okinawa's history, culture and natural history is easily one of the best museums in Japan. Displays are well laid out, attractively presented and easy to understand, with excellent bilingual interpretive signage. The art-museum section holds interesting special exhibits (admission prices vary) with an emphasis on local artists. It's about 15 minutes' walk northwest of the Omoromachi monorail station.
