The Event passed down in Nishikoiso, Oiso, is known for the bamboo carried by children and for customs that differ between the East and West districts. With wishes to ward off epidemics, bring a good harvest, and bring rain, the participants walk around the district with bamboo decorations, then send the bamboo mikoshi out to sea.

About Nishikoiso Tanabata Event

The Nishikoiso Tanabata Event is a Tanabata festival led by children, passed down in the Nishikoiso district of Oiso.

It is not an event celebrating the legend of the Cowherd and the Weaver Girl; rather, it is intended to ward off epidemics and purify the village before the season.

It is also distinctive in its use of bamboo decorations and a dragon-shaped bamboo mikoshi, with different forms of the tradition passed down in the East and West districts.

Festival highlights

Highlights include the ritual of sweeping the Dosojin and the ground with bamboo decorations adorned with tanzaku strips, and the dragon-shaped bamboo mikoshi made by bundling bamboo decorations together.

In Nishikoiso West, there is a custom of performing the Tanabata dance and striking the bamboo mikoshi against utility poles. In Nishikoiso East, a mandō lantern is erected, and the bamboo mikoshi is shaken as prayers are recited.

One interesting aspect is that these neighboring districts differ in who takes part, the form of their bamboo mikoshi, and how they carry out the event.
