The main building of the Flour Mill Museum is a renovated old house where the Masuda family, founders of Nisshin Seifun, lived. Inside the building, you can see displays of household items from the early Showa period and photos from that time, which show how the family's lifestyle changed as the flour industry developed. In addition, the museum displays the flour milling process and machinery from the time of its founding, allowing visitors to learn about the historical flow of the flour industry. The main building, which offers a historical atmosphere, is recommended for those interested in the flour industry or those who want to learn about Japan's history!
