This open-air museum hosts a collection of 25 traditional buildings, mostly from the Edo period (1603 - 1868). They were relocated to the museum from around the country. Every building has been designated a Cultural Property, and they house displays of agricultural equipment and folk tools used in the home. You'll feel you've slipped back in time while enjoying the seasons, including springtime cheery blossoms and autumn leaves. The folk houses host storytelling, performing arts, and lots of other events, as well as a variety of hands-on programs. You can learn about the buildings at an exhibition in the main hall, where they hold planned exhibits too. Their Traditional Craft Hall is open for everyone to experience old-fashioned indigo dyeing.
