Dewa Sanzan Flower Festival

The Dewa Sanzan Flower Festival

Put simply, the warmer months are an excellent time to visit the Dewa Sanzan, and not just for the Dewa Sanzan Flower Festival. Not only did Matsuo Basho visit the Dewa Sanzan during this time, but Mt. Gassan and Mt. Yudono are open for hiking, the Mt. Haguro Five Storied Pagoda Light Up is on, and festivals abound in the shrines in the surrounding towns and villages. In addition, for Yamabushi (mountain monks) of the Dewa Sanzan, there is a ‘Peak’ ritual for each of the seasons. The most famous is the Akinomine Autumn Peak Ritual that culminates in the Hassaku Festival at the end of August. However, the Dewa Sanzan Flower Festival, or Hanamatsuri, that began with the Natsunomine Summer Peak Ritual, is just as unmissable. Still looking for a reason to add the Dewa Sanzan to your bucket list? If you’re in town over the summer, why not come check out the festival of flowers on Mt. Haguro.

The Summer Peak Ritual and the Dewa Sanzan Flower Festival

For millennia, the placing of flowers in front of gods has been a way to ward off evil in Japan. Originally, July 15th on the lunar calendar (June 15th on the Gregorian calendar) marked the end of a 96-day period when flowers were dedicated to the three Buddhist avatars of Mt. Haguro. Moreover, the start of this period coincides with an important period on the Buddhist calendar known as Higan, two periods of seven days with the middle day falling on the spring equinox. In addition, it concludes when most flowers are in full bloom. On the 14th of July, Yamabushi struck bells at midnight in dedication to peace in the current world, and at dawn the next morning in dedication to enlightenment in the next. Collectively, this became known as the ‘Flower-offering Peak’.

During this 96-day period, unaffiliated Yamabushi brought their followers or apprentices to join in their training. Their aim was simple; rid the polluting thoughts of the present world, and gain enlightenment in the next. Over time, this training became the Natsunomine Summer Peak Ritual. The final day of the summer peak ritual culminated with a flower festival at the top of Mt. Haguro. Since then, the festival became known as the Dewa Sanzan Flower Festival, and is one of the main annual festivals of Dewa Sanzan shrine.

What happens at the Dewa Sanzan Flower Festival?

At 9am on the 14th of July, the Kiribi Fire Ritual, allegedly the oldest ritual in Japan, begins. Then from 2pm, children carry a Mikoshi movable shrine through town starting at the Zuishinmon gates at the bottom of Mt. Haguro. From 10am on July 15th, there are local performing arts on show starting with Kurokawa Noh in front of Prince Hachiko Shrine next to Sanjingosaiden Shrine at the top of Mt. Haguro.

Officially, the festival starts at 10am in the main shrine building, but the real events don’t start until noon. The real Dewa Sanzan Flower Festival is a parade with a giant Brahma Deva. The Brahma Deva is in the form of a bunch of artificial flowers suspended from a giant lantern called a Manto (lit. many lanterns). This Brahma Deva represents the three gods of the Dewa Sanzan, with the flowers representing a rice flower, in dedication of a good harvest. The parade goes clockwise around the Kagami’ike Mirror Pond in front of Sanjingosaiden shrine. The parade includes high-ranking Yamabushi, a sacred tree, a Mikoshi moving shrine, and Miko shrine maidens. The Dewa Sanzan Flower Festival concludes with one trip around the Kagami’ike Mirror Pond, and a ceremony where flowers are given out to the lucky afterwards.

Feeling brave?

Still looking for a reason to visit the Dewa Sanzan? What better reason than favourable treatment from the gods? When the parade comes around, join the locals as they fight to grab one of the flowers. If you’re lucky enough, grab one and you will get blessings and favourable treatment from the gods. Take it home and decorate in your entrance to pray for a good harvest, safety in the home, and to ward off evil spirits.

Getting to the Flower Festival

Read this article about how to access the Dewa Sanzan. Put simply though, Mt. Haguro is best accessed by private car, as the busses can be infrequent. There is ample parking near Zuishinmon at the Ideha Cultural Memorial Hall at the base of the mountain near the Five Story Pagoda. This is where the children’s Mikoshi moving float takes place on the 14th of July at 2pm. The Zuishinmon gates is also where the climb up the 2,446 steps through the cedar forest, past the five-storied pagoda, to Sanjingosaiden shrine at the top begins. If you do drive to the shrine at the top, bear in mind that there is a ¥400 fee for cars. There is a short walk from the car park to Sanjingosaiden shrine where the main events on the 15th of July are held from 9am.

Here’s a guide on how to hike the Dewa Sanzan. Looking for a place to stay? The Shukubo of Mt. Haguro near the Zuishinmon gates is a great place to start.

Here is a bus timetable for those that need it. Zuishinmon at the bottom of the mountain is on the timetable as “Haguro Zuishinmon”.  In addition, “Haguro Sancho” on the timetable is located at the top of Mt. Haguro. The bus stops at the same car park the cars use, so there is also a little walk to Sanjingosaiden shrine.
