Weeding an overgrown sitewas where the Yoisho group began.

The Okadaira Yoisho Society is a volunteer group formed in March 1995 (Heisei 7). Local residents began by weeding the overgrown site, and monthly weeding remains a regular activity. According to the village, the 5 p.m. chime on its disaster radio plays an ode to the Okadaira Shell Mounds.
- Formed March 1995
- Weeding once a month
- 5 p.m. chime is an ode
