In the Kosuge Hashiramatsu Ritual, teams compete to light 2 Hashiramatsu, entrusting their hopes for peace throughout the land and a bountiful harvest to the outcome. Held as the annual festival of Kosuge Shrine in Mizuho, Iiyama City, it has been passed down alongside the eve-of-festival observances, processions, and fire rituals.

About Kosuge Hashiramatsu Ritual

The Kosuge Hashiramatsu Ritual is the annual festival of Kosuge Shrine, located in the Kosuge district of Mizuho, Iiyama City.

Prayers for a bountiful harvest and peace throughout the land are offered through a series of events: the eve-of-festival observances, the main festival, the annual festival procession, the village shrine procession, the Hashiramatsu procession, and the Hashiramatsu ritual.

Local young men, the Matsumiko, and several settlements take part, preserving the tradition of erecting Hashiramatsu and setting them alight.

The event is also designated an Important Intangible Folk Cultural Property.

Festival highlights

The main highlight is the contest in which young men split into upper and lower groups, carry the Matsumiko, and race to the Hashiramatsu to see who can light the obana at the top first.

The sound of the drums signals the start. Once the fire catches, the Matsumiko is brought down and the Hashiramatsu is toppled.

It is said that if the upper group wins, there will be peace throughout the land, while a win by the lower group brings a bountiful harvest, tying the outcome to the prayers.

There is also a tradition of spectators taking home the toppled obana and matsusakaki branches.
