Origins and History of Sayado Koshogatsu Decorations

Sayado Koshogatsu Decorations have been passed down in connection with life in the Sayado district, where many households once raised silkworms.

Mayudama made from rice flour and other decorations associated with silkworms remain, making this a culture that reflects the region’s traditional livelihood.

Now that fewer households hold the event, the preservation society is taking the lead in passing it on to the next generation.

In 2005, it was designated an Important Intangible Folk Cultural Property of Midori City.
