This museum displays about 2,500 valuable materials featuring the history of land reclamation and the defense of Hokkaido, including the history of Tondenhei farmer-soldiers, who were tasked with land reclamation and the defense of Hokkaido, and of the Imperial Japanese Army’s 7th Division. Exhibits also include those about activities for local communities carried out by the 2nd Division of the Japan Ground Self-Defense Force (JGSDF), which grew out of the National Police Reserve that was established after World War II and that was then reorganized as the National Security Force.
