The Arasuke-numa-iri Bonten observance, passed down in Arasuke, Daigo, Yokote City, is a local annual event in which a bonten is dedicated at Benten-numa. The pond-entry ritual and tawara-bonten express hopes connected with water and rural life.

About Arasuke-numa-iri Bonten Observance

The Arasuke-numa-iri Bonten observance is an annual event passed down in Arasuke, Daigo, Yokote City.

Before farm work gets underway in earnest, a bonten is dedicated to Benten-numa, which has supplied the village’s irrigation water.

A distinctive feature is the participation of young and middle-aged adults who married, built a new home, or had a child in the past 1 year.

The observance carries prayers for a good harvest and safety at home, and reflects the close ties between water and local life.

Festival highlights

The highlight is the moment when participants enter Benten-numa and place the bonten in a designated spot as an offering.

The bonten dedicated here is also called a “tawara-bonten,” and the distinctive practice of carrying it into the pond has been passed down.

It is said to closely resemble the scene described in Sugae Masumi’s “Yuki no Dewaji,” and is regarded as an observance that preserves an old custom.

What to expect

During the observance, local young and middle-aged adults make their way together to Benten-numa and enter the pond.

Participants carry the bonten to an approximately predetermined spot, set it in the pond, and dedicate it.

Participants include people who married in the past 1 year, built a new home, or had a child, among others.

Before farm work begins, villagers who rely on the blessings of water pray for a good harvest and safety at home.

How to take part

Those who take part in the event are described as young and middle-aged local people who, during the past year, have newly married, built a house, welcomed a child, or had a similar life event.

For this reason, whether general visitors can enter the marsh or take part in the bonten offering must be confirmed individually.

It is also a good idea to ask the organizers before the event whether viewing only is possible and whether areas or locations for spectators will be designated on the day.
