Tomioka Silk Mill is the Japan's first modern factory founded in Tomioka city.

It was designated as a national historic spot in 2005.
And, it was designated as World Heritage Site in 2014.

Tomioka city is located about 15 km southwest of the center of Takasaki city.
The factory is about 0.6 km southwest of Joshu-Tomioka station on Joshin Railways.

After opening the country in the 1860s, silk was one of Japan's important exports.
But it was handcrafted in Japan to spin silkworm cocoons into a thread.

By rapid increase in exports, production bottlenecks reduced the quality substantially.

In the result, the Japanese government decided to found a modern factory with large-scale machines.

So, the government imported silk reeling machines and steam engines from France, under the lead of Paul Brunat who was a French engineer staying in Japan.

Then the large factory was built in Tomioka city boasting a sericultural industry in 1872.

This state-run factory had several hundred excellent female workers from all over the country.
And it had created high-quality silk again, then the Japanese silk gained a high reputation from abroad.

In 1893, this factory was sold into private hands.

Because cheap silk from China had increased since the 1970s, the factory has led to decreased the production.
And the operation had been ended in 1987.

Most buildings in this factory are relatively in good preservation.
