Raw silk inspection station (unknown date)
Silk Conditioning House in Yokohama, Kanagawa Prefecture. Designed by Oto Endo (1866-1943), a pioneer in reinforced-concrete design, the building was completed in 1926 (Showa 1). It still stands today and is used as the Yokohama No. 2 Joint Government Office Building. At the start of the 20th century, silk was Japan's main export product (mainly to Europe and the US). As the quality of raw silk is difficult to measure, absorbs much moisture and was largely sold by weight, this government run institution was inaugurated in August 1896 (Meiji 29) to test silk for weight and quality.
