This is an inspection of cocoon quality to ensure smooth and fair trading. In accordance with the Sericulture and Silk Industry Law, this is carried out by prefectural cocoon inspection offices. Items related to raw silk volume include the cocoon selection rate and raw silk rate, while items related to cocoon quality include the unwinding rate and cocoon thread length. In the past, cocoon thread fineness, small nodes, and cocoon uniformity were also included in the inspection items as points to increase or decrease cocoon quality, but these have not been used since 1965. With the automation of silk reeling, cocoon inspection is now also done by automatic reeling.
