Sumomo Matsuri (2015)
Time Out says
According to legend, the warlord Minamoto no Yoriyoshi and his son Yoshiie stopped to pray for victory in the Zenkunen War (1051-1063) at this Fuchu shrine. Their wish was eventually granted, and the Sumomo (named after the plum that Yoriyoshi is said to have offered to the gods) festival began. You'll be able to try the plums for yourself at the many food stalls set up on the grounds, and if you're an amateur farmer, don't forget to participate in waving a fan decorated with drawings of crows – this is supposed to help keep the birds away from your crops.
