The Takayama-sha Sericulture School is a national historic site and is one of the three Related Sites that has just been inscribed for the World Cultural Heritage along with Tomioka Silk Mill. In 1883, Chogoro Takayama established a sericulture method called seion-iku, which carefully regulates ventilation, temperature, and humidity. He also organized a private sericulture school in 1884. Takayama-sha's students came not only from inside Japan but also from China and the Korean Peninsula. As a result of this school, seion-iku became the standard method of sericulture in Japan.
