Guide
The Okaya Silk Museum (affectionately known as 'Silk Fact Okaya') is a unique facility in Okaya City, Nagano Prefecture, that features an integrated silk reeling factory. This museum plays a vital role in preserving and communicating the history of silk, the development of Japan's silk industry, and the local history of Okaya. Its most striking feature is the presence of an actual silk reeling factory within the museum grounds, providing a rare environment where visitors can observe the movement of functional silk-reeling machinery alongside traditional exhibits. It is a multifaceted facility where you can learn about silk-related technology and culture through live demonstrations and detailed displays.
Okaya City has a rich history as a major hub for the silk industry. The predecessor to this museum opened in 1945 and has long supported the region's industrial culture. The current facility was renovated using the site of the former National Institute of Agrobiological Sciences and now includes the Miyasaka Silk Reeling Plant. The name 'Silk Fact' carries a dual meaning: 'factory' (referring to the silk reeling plant) and 'fact' (representing the truth and reality of the silk industry), preserving its immense value as an industrial heritage site.
The museum is divided into three main areas: the Entrance Area, the Museum Area, and the Community/Workshop Area. The Entrance Area features a gallery, lounge, and museum shop showcasing local brands and industrial heritage. The Museum Area focuses on the biology of silk and silkworms, as well as the evolution of the silk industry in Okaya. Key highlights include displays of French-style silk-reeling machines (similar to those used at the Tomioka Silk Mill) and locally developed machinery, which are essential for understanding technological transitions. Furthermore, at the adjacent Miyasaka Silk Reeling Plant, you can witness the actual operation of silk-reeling machinery.
The museum is open from 9:00 AM to 5:00 PM. While you can learn about silk technology regardless of the season, exhibition schedules and special events change periodically; it is highly recommended to check the latest information before your visit. Visiting during daylight hours allows for the best observation of the intricate details of the machinery and historical documents.
The facility includes multi-purpose spaces for meetings and events, as well as areas for workshops. These spaces offer opportunities to engage with silk culture through hands-on activities, such as making crafts using silk or cocoons. There is also a space where silkworms are raised, allowing visitors to deepen their understanding of sericulture from a biological perspective.
Okaya City is dotted with various cultural landmarks. Nearby sites such as the Ilfu Children's Museum, the Art and Archaeology Museum, and the former Hayashi Residence (a designated Important Cultural Property) can all be visited using a common admission ticket. Combining these visits is an excellent way to gain a deeper understanding of the local history and culture.
Since the museum contains many delicate exhibits and machinery, comfortable walking shoes are recommended. Please follow the designated routes and respect the boundaries between exhibition and work areas. Photography may be restricted in certain areas; please follow the instructions of the staff. As this is a public facility, please handle all exhibits and machinery with extreme care.
