Dewa Sanzan Hassaku Festival on Mt. Haguro

Written by Timothy Bunting

Hassaku Festival on Mt. Haguro

Cicadas blearing, rice fields of bright green leaves, fireworks on show, it’s summer in Japan and that means one thing; festivals. When the weather heats up, communities gather outside at night under the lanterns and let the sake flow. Traditionally, festivals in Japan are a celebration of successful farming, when communities show their appreciation to the gods. For the agricultural community of the Dewa Sanzan, the Hassaku festival on August 31st is one of the most important, especially for the Yamabushi. Seeing 150 Yamabushi chanting in unison under the dim light of the lanterns and fire is a wonderful sight to behold.


What is the Hassaku Festival?

At this time of year, the rice plants begin to ripen. In the past, people in farming communities celebrated by sending newly-harvested grains to their supporters on this day. Before long, these celebrations passed on to the people in the towns and villages. Then, the Hassaku festival developed as a prayer to the gods for protection from natural disasters that would destroy crops.


Hassaku comes from two words, Hachigatsu, meaning August, and Sakujitsu, meaning the first day of the month. So why is the Hassaku festival on August 31st? Well, much like the Dewa Sanzan Flower Festival in July, the Hassaku festival is originally based on the lunar calendar.


What happens at the Hassaku Festival?

The Hassaku festival corresponds with the Akinomine Autumn Peak Ritual, and the annual festival of Prince Hachiko Shrine. The Akinomine Autumn Peak Ritual is the most important for Dewa Sanzan Yamabushi, with up to 200 joining in. In addition, Prince Hachiko was the founder of training on the Dewa Sanzan. So, in essence, the Yamabushi are following in the footsteps of the founder of the Dewa Sanzan from 1400 years ago.


At 10pm on the 31st of August, Yamabushi announce the results of their training at Prince Hachiko Shrine. Then, they light a bonfire, called Daisaitogoma, in front of the shrine where they perform special rituals. The Daisaitogama fire is to both commemorate the souls of the ancestors, and call upon the gods.


Once the fire is ready it is time for the Hibashi ritual. Here the Yamabushi perform a dance with 4m-long sticks, turning around and dancing around in the burning ash. In addition, the other Yamabushi walk around in a snake-like fashion chanting the whole time creating an electric atmosphere. The Hibashi ritual is to pray for a bumper crop, and the health of every household. Lastly, from midnight, the Denmensai festival begins at Sanjingosaiden Shrine, where the Yamabushi pray for resilience against typhoons and strong winds.


Getting to the Hassaku Festival

The Hassaku festival takes place at Prince Hachiko Shrine at the top of Mt. Haguro next to Dewa Sanzan Shrine. If you’re coming by car, we recommend getting there early, around 8:30-9pm, to get a good park. Otherwise, a special bus service will run during the duration of the festival connecting central Tsuruoka. More information below.


Accommodation for the Hassaku Festival

If you’re coming to specifically see the Hassaku festival, we’d recommend staying in Saikan right next door. You’ll also get the opportunity to try Dewa Sanzan Shojin Ryori, exactly what this festival is about. However, take note that Saikan will be busy with preparations for the festival throughout the night. If that bothers you, take advantage of the special busses and stay in a Shukubo at the bottom of Mt. Haguro. Read our article on accessing the Dewa Sanzan for more.
