Kamiarizuki: Why Japan’s Gods Gather at Izumo Taisha in November

Across Japan, the tenth month of the traditional lunar calendar is known as Kannazuki, the month without gods. In the coastal region of Izumo, however, that same season is celebrated as Kamiarizuki, the month with gods.

According to Shinto tradition, the myriad deities from throughout the country journey to Izumo Taisha to convene in council. For about a week, they consult together to deliberate on harvests and bind the invisible ties of human fate.

Why do the deities gather in Izumo?

The tradition traces back to Japan's ancient founding chronicles, including the eighth-century Kojiki. According to myth, the benevolent terrestrial ruler Okuninushi no Kami ceded control of visible temporal affairs to the heavenly descendants of the sun goddess Amaterasu.

In exchange for relinquishing the visible land, Okuninushi received authority over the unseen world, encompassing spirits, divine affairs, and invisible connections. Izumo Taisha was established as his sacred sanctuary. Because he watches over hidden ties, the deities gather annually at his shrine for a sacred conference known as Kamuhakari.

What is decided during the divine assembly?

During this seven-day council, the visiting deities deliberate upon the unseen threads that shape daily life. While many visit seeking marriage blessings, tradition holds that the deliberations encompass much broader human relationships.

• Romantic unions and long-lasting marriages
• Fortunate connections between friends, colleagues, and neighbors
• Agricultural prosperity and bountiful harvests
• Fruitful business partnerships for the coming year

Japanese art and folk traditions often portray the assembled deities busily tying together wooden tablets inscribed with human names. Okuninushi confirms each connection, giving rise to the Japanese concept of en-musubi, the spiritual binding of life ties.

How does Izumo welcome the visiting gods?

The gathering begins with the solemn evening rite of Kami-mukae-sai on the sands of Inasa Beach, west of the grand shrine. Purifying bonfires burn at dusk as priests welcome the arriving deities from across the sea.

1. Priests receive the deities into sacred branches sheltered on both sides by white silk curtains.
2. Guided by a dragon-serpent deity, a quiet torchlit procession escorts the gods inland to Izumo Taisha.
3. The deities are enshrined in the Jukusha, two long wooden lodging shrines flanking the main sanctuary.
4. Deliberations proceed quietly over seven days at the nearby Kami-no-miya shrine.
5. The council concludes with Karasade-sai, a farewell ritual sending the deities on their return journey.

During the assembly, rituals remain hushed so as not to disturb the divine discussions. Historically, local residents even refrained from loud noises and festivities during this sacred week.

Visiting Izumo Taisha

Izumo Taisha welcomes visitors throughout the year, but the atmosphere around Kamiarizuki offers deep reflection. Because the festival follows the traditional lunar calendar, dates change each year and typically fall in November.

• Reaching the shrine: Take a 25-minute bus or Ichibata Electric Railway train from JR Izumoshi Station to Izumotaisha-mae Station, or catch an airport bus from Izumo Airport (about 40 minutes).
• Shrine etiquette: Unlike the usual two-bow, two-clap, one-bow practice at most shrines, Izumo Taisha observes a four-clap prayer tradition (two bows, four claps, one final bow).
• Respectful conduct: During evening ceremonies at Inasa Beach, do not step on the sacred straw mats laid along the sand, and avoid using flash photography.
