As one of the last places still making yuki tsumugi - an entirely handmade silk fabric - Omoigawa Weaving House is full of stories. One that caught my eye were these rotating boxes for the cocoons.

By rotating these boxes each day until the worms settled down to cocoon manufacturing, it satisfied the worms urge and kept things orderly for the farmers.
