The “Silk Fact Okaya” nickname

In Okaya Silk Museum, there is a Silk Reeling Factory (Miyasaka Silk Mill). Thus museum is a rare kind in the world. We hope to announce both the “Factory” and the “Fact” of Okaya Silk Industry. So we call Okaya Silk Museum “Silk Fact Okaya” as a nick name.

The Miyasaka Silk Mill in operation

The Miyasaka Silk Mill operates unchanged from silk making’s heyday. Here visitors can observe Suwa type silk reeling machines and Japan’s old-style Joshu type reeling machines in actual use.
Working machinery from the former National Institute of Agrobiological Sciences is also on display.



On arrival the first thing visitors see is the museum’s saw roofed facade. This was inspired by the Department of Agriculture and Forestry’s Okaya Silk Experiment station, Inspection Center, constructed at this location in 1948.

When visitors enter they find the lounge and gallery, a museum shop, an Okaya information corner, and a display showcasing a tour of the local silk related “Heritage of Industrial Modernization.”
