Takayama-sha Sericulture School

Takayama-sha Sericulture School (高山社跡, Takayama-sha Ato), founded in 1884 by former samurai Takayama Chogoro, played a key role in shaping Japan’s modern silk industry. Takayama developed the innovative “seion-iku” method, which controlled both temperature and humidity to create optimal conditions for silkworm farming. The school’s two-story main building, constructed in 1891, featured a raised roof, numerous windows, and fireplaces—design elements that helped maintain a stable climate for growing high-quality silkworms. This method significantly influenced the production of silk in Japan and attracted students from across the country and abroad, eager to learn and replicate the successful techniques.

Today, visitors can explore the historic site by entering through a traditional gate and joining guided tours (offered in Japanese). The preserved main building, which still houses the original trays used for silkworms on the second floor, offers a glimpse into the past. Although many of the original structures have been lost or damaged over time, restoration efforts are underway to return the site to its Meiji-era appearance. The Takayama-sha Sericulture School, along with the Tomioka Silk Mill, was designated a UNESCO World Heritage site in 2014, acknowledging its pivotal role in the development of Japan's silk industry.
