What it is

Niiname-no-Matsuri, also known as Niiname-sai, is one of Japan’s most significant Shinto rituals. Each year, the Emperor of Japan leads ceremonies to express gratitude to the deities for the year’s rice harvest and to pray for prosperity in the coming year. The ritual is deeply tied to the spiritual and agricultural rhythms of Japanese life, reflecting a belief that ancestral spirits and divine forces are present in the rice that sustains the nation. While the main ceremony is held at the Tokyo Imperial Palace, similar observances take place at major Shinto shrines across Japan.

Where it comes from

The origins of Niiname-no-Matsuri reach back to ancient Japan, when people held domestic rites in November to honor their ancestors, the god of food, and the hearth deity. These rites, believed to invite ancestral spirits through the rice, were central to community and imperial life. Historically, the festival’s date shifted according to the lunar calendar, but it was fixed to November 23 during the Meiji period. The first Niiname-sai for a new emperor, called Daijō-sai, forms part of the enthronement ceremonies, highlighting the ritual’s enduring imperial significance.

How it is celebrated

During Niiname-no-Matsuri, the Emperor offers thanks for the year’s crops and prays for future abundance. The ceremony unfolds over two days: one dedicated to the kami (deities) and the other to the emperor himself. Key rituals include presenting offerings of sake, rice porridge, and steamed rice on wooden vessels, set on a red mat, to Amaterasu, the sun goddess. The emperor performs purification rites and changes robes between the evening and dawn ceremonies. While the central observance is at the Imperial Palace, major shrines such as Ise Grand Shrine and Izumo Shrine also hold their own ceremonies, and the day is recognized nationwide as a time to reflect on the harvest and express gratitude.

Joining in

Visitors in Japan on November 23 may notice special ceremonies at major Shinto shrines, especially Ise Grand Shrine and Izumo Shrine, though the Imperial Palace ritual itself is not open to the public. Across the country, the day coincides with Labor Thanksgiving Day, and many people take the opportunity to give thanks for the year’s work and harvest. While the core imperial rites are private, the atmosphere at shrines is respectful and reflective, offering a chance to witness Japan’s deep connection between spirituality and the cycles of nature.
