Atago Shrine (Kasama) [Ibaraki]

【Overview of Atago Shrine (Kasama)】

Atago Shrine is situated atop Mt. Atago (elevation 306m) in Kasama City, Ibaraki Prefecture. Founded in 806 (Daido 1), it traces its origins to the high priest Tokuitsu Hosho, who opened the mountain as a sacred site of Shinto-Buddhist syncretism.

The shrine enshrines five primary deities, with Hinokagutsuchi no Mikoto as the main deity, alongside Izanami no Okami, Homusubi no Mikoto, Mizuhanome no Mikoto, and Haniyamehime no Mikoto. As one of Japan’s three major shrines for fire protection, these five deities symbolize the harmony of natural elements: fire, water, and earth.

【Who was Tokuitsu Hosho?】

Tokuitsu Hosho was a legendary high priest of the early Heian period, often called the “Founder of Northern Japanese Buddhism.” Moving from the capital (Nara) to the east, he opened many sacred sites, including Mt. Tsukuba (Chuzen-ji Temple), Mt. Atago (Kasama), and Enichi-ji Temple in Fukushima. He was a premier leader of Buddhism in Eastern Japan; even the famous Kukai (Kobo Daishi) respected him as a “superior master of the east” and sent him books to seek his teachings.

The current hall is said to have been reconstructed in the 1750s (Horeki era) during the mid-Edo period. Built in the Irimoya style, it features a large Chidori-hafu (gable) and an intricate porch (kohai).

The carvings of dragons and lions on the pillars and beams are exceptionally detailed. By special courtesy, I was able to view the interior, which housed historical paintings and Tengu ornaments.

Located further behind the main hall, at the very top of a set of stone steps, is Izuna Shrine. While its exact founding date is unknown, it was already recorded in Edo-period documents. Historically known as “Izuna Gongen,” it was a site where Shugendo monks practiced rigorous mountain asceticism.

It enshrines Tajikarao no Mikoto, the “God of Strength” famous for his unparalleled power in the legend of the Heavenly Rock Cave.

【Ihari Shrine: An Ancient “Shikinaisha” within the Inner Sanctuary】

Behind Izuna Shrine sits a small, hexagonal building (Rokkakuden) which enshrines Ihari Shrine, an ancient Shikinaisha (a shrine listed in 10th-century government records).

It enshrines the kitchen/hearth deities Okitsuhiko no Kami and Okitsuhime no Kami.

【Why is Ihari Shrine at the Deepest Part of Atago Shrine?】

When Tokuitsu Hosho invited the spirit of “Atago Gongen” to the mountain in 806, the entire mountain became known as “Atago.” However, the original local deity, Ihari Shrine, continued to be worshipped in the most sacred area at the very back. This suggests that Ihari Shrine is the “original god of the mountain” (the Jishinigami or landlord deity), predating Atago Shrine.

The bronze hexagonal hall features a golden phoenix on its roof and the Imperial Chrysanthemum crest.

This prestigious design represents the highest respect paid to the “original god” who has protected this mountain for over 1,200 years.

【The Legend of the “Thirteen Tengu”】

Surrounding Ihari Shrine are 13 stone shrines arranged in a semi-circle, representing the Thirteen Tengu of Mt. Atago. Legend says these 13 Tengu used their supernatural powers gained through ascetic training to heal the sick and predict the weather, acting as “messengers of the gods” to bring happiness to the people. These stone shrines stand in a row along the cliff, each serving as the dwelling for one of the thirteen Tengu.

Admin’s Impressions

At the 306m summit lies not only the history of Tokuitsu Hosho from 1,200 years ago but also the much older roots of Ihari Shrine. The coexistence of old and new deities, cherished across generations, is the greatest charm of this place. Located behind the Izuna Shrine hall, it was a bit hard to find, but it felt like a truly sacred space. Since this area has a strong character as a “place of ascetic training” rather than a mere tourist spot, visitors should remain quiet and respectful. It is clearly a shrine still deeply loved today, as many people were hiking up from the first torii.
