What is the significance of this event? Technically, the mikoshi is a transportation vehicle for the local kami (deity). When the mikoshi is taken out from the shrine, it is believed that the spirit of the kami enters the mikoshi and then it is paraded, with overflowing enthusiasm, around the neighborhood.
And as you can see from this photo, the team of mikoshi bearers includes a lot of people, from strong young men (who are actually bearing the weight) to teenagers, elders and... girls. And, a few years ago, I even had the chance to be a Mikoshi bearer...
