A shrine in western Japan holds an unusual prayer ritual every year to celebrate Children’s Day.

“Crying Sumo” matches two babies against each other.

The first one to cry is the winner.

Priests believe the babies’ crying chases away bad luck as they pray for them to grow up safe and strong.

This year, 70 babies from six months to one-year old attended with their parents.

Parents and children both end up laughing and enjoying the festivities.
