The museum of history and folklore allows visitors to follow the history of Shimonita-machi from antiquity up until modern times. The museum contains exhibits of Shunju-kan Bunsho (administrative archives from Shunju-kan, the administrative body that operated Arafune Cold Storage), and a replica of the Arafune Cold Storage during its heyday among other exhibits, enabling visitors to appreciate the historical significance of the site. The Shunju-kan Bunsho is a set of 1081 papers left at the Shunju-kan documenting details such as contracting of silkworm egg storage from around the country, the management situation at the time, and ledgers and business pamphlets showing how the facility operated. This set of papers is also an important cultural property of Shimonita-machi.
