The Yaya Matsuri, held in Owase, Japan, during the first week in February, features mikoshi (portable shrines) carried through the streets by groups of young men who meet and deliberately crash into each other. The festival takes its name from their shouts—”Yaya! Yaya!”—as they run into one another. Several special events, including dances, are held during the five-day festival. On the last night, there is a ceremony at the Owase Shrine to determine who will participate in the festival the next year. Discuss
