Address: Tomioka Silk Mill, Tomioka, Gunma Prefecture, Japan

Website: https://www.tomioka-silk.jp/en/

Tomioka Silk Mill is a 19th-century silk-reeling factory in Gunma Prefecture, Japan, established in 1872 as a state-supported model for modern silk production. It is notable for its preserved industrial buildings and early adoption of mechanised reeling techniques.

The site contains the original multi-storey brick mill and several timber production halls where reeling and testing machinery are displayed. Exhibits include preserved machines, interpretive panels, and examples of silk products, suitable for a short focused visit of about 1-2 hours. The complex also includes managers’ residences and workers’ housing that illustrate workplace organisation and daily life around the mill.

Built by the Japanese government in 1872 to introduce mechanised silk-reeling and raise export quality, the mill served as a model for industrial silk production in Meiji Japan. The complex continued in industrial use into the 20th century and has since been conserved and opened to the public as a heritage site.

The mill complex sits in Tomioka city in Gunma Prefecture, in the north-central part of Honshu. It is accessible by road and local rail from Takasaki and other regional centres.

• Visitor note: Open-air displays and restored machinery are concentrated in a compact site suitable for a 1-2 hour visit; guided tours and interpretive panels explain silk-reeling steps.
• World Heritage status: Inscribed as part of a World Heritage listing in 2014 for its role as a model modern industrial facility in Meiji-era Japan.

What to See#

• Main Silk Mill (brick building): The principal brick mill building is a Western-style, multi-storey structure dating to the original 1872 complex and houses preserved reeling machinery and exhibition space.
• Wooden workshops and reeling houses: A cluster of timber workshops and former production halls where hand and machine reeling took place; several have been conserved and fitted with displays explaining silk production processes.
• Managers’ houses and workers’ housing: Residential and administrative buildings for managers and foreign technical staff, including preserved living quarters and offices that illustrate social organisation at the mill.

Tomioka Silk Mill is in Tomioka city, Gunma Prefecture. The usual approach is by train to Tomioka Station (JR Shin’etsu Line); from Tomioka Station it’s roughly a 15-25 minute walk to the preserved mill site, or a short local bus or taxi ride.

• Visit on a weekday morning to avoid school group crowds that often arrive later in the day; the preserved factory buildings are compact and become congested when groups enter.
• Approach from Tomioka Station and follow the signed short walk to the site - the mill is designed for pedestrian access from the town and is not far from the station.
• Check the official site before you go for any conservation closures; some buildings or interior exhibits are occasionally closed for preservation work and the timetable is posted in advance.
