Tomioka Silk Mill in Gunma Prefecture, 19th century factory buildings symbolizing Japan’s industrialization is likely to become one of the World Heritage after an official approval by UNESCO’s committee in June. The city of Tomioka, a manager of the buildings will start considering repair and preservation works.
The factory was founded in 1872 as the first state-owned silk mill. The government employed French silk reeling engineer and construction designer to build the factory. The buildings feature timber-frames and brick walls. The east cocoon warehouse has been preserved as it was first built. The mill, sold to the Mitsui Conglomerate later, was in operation for 115 years.
The city is addressing management of the historic structures, while some experts estimate the repair cost at as much as 10 billion yen. The prefectural government intends to conduct detailed investigation for the cost estimation, establishing short, mid and long-term plans toward completion. (2014/04/30)
