Usuiseishi Co., Ltd. is one of only two raw silk reeling factories remaining in Japan. It processes 60% of all Japanese silkworm cocoons and produces most of Japan’s raw silk. The location of the current Usuiseishi headquarters was originally owned by a different company. This company collected silkworm farmers’ frison, sticky waste silk, and made it into a soft silk stuffing. By 1959, this factory was in danger of going out of business, and it was purchased by a farmer cooperative. In 2017, it incorporated into Usuiseishi Co., Ltd. Today, the factory is supported by the government, organizations, and private individuals in order to continue operating as an important relic of one of Japan’s former great industries.
