The primary kami of Akibasan Hongū Akiba Jinja is the Kagu-tsuchi, the kami associated with protection against fires. During the Edo period, this kami was popularly called the Akiha Gongen and was identified with Kannon Bosatsu under the Shinbutsu shūgōsystem of combined Buddhism and Shinto.
History
Per shrine tradition, the Akibasan Hongū Akiha Jinja was established in 701 as a Buddhist temple by the famed priest Gyōki. It was named Akiha-dera from a poem written by Emperor Saga in 709. During the Heian period it became a center for the Shugendōcult and was associated with the Shingon sect, although much of its subsequent history is uncertain. After the start of the Tokugawa bakufu, retired shōgunTokugawa Ieyasu ordered the temple to convert to the Sōtō Zen sect. Tokugawa Tsunayoshi in particular favored its blend of Shinto, Buddhism and Shugendō, and promoted the spread of the Akiha cult throughout the country to provide protection against fires. Despite its remote mountain location, the temple became a popular pilgrimage detour from the Tōkaidō for pilgrims on their way to Ise Shrine or Kompira Shrine, or on their way back to Edo. However, in 1685, the government banned the traditional ceremony of carrying the shrine's mikoshi along the Tōkaidō Mount Akiha towards Edo and Kyoto, for fear that the riotous procession would disturbpublic order. The banconversely helped spread the Akiha cult throughout the country through the establishment of numerous branch shrines, especially in the Chūbu region of Japan. Major Sōtō temples and monasteries often established a small Akiha shrine within their grounds. After the Meiji Restoration, and the 1872 laws separating Buddhism and Shinto, the Shugendō cult was abolished, Buddhist images and implements were removed from the mountain to a new temple in Fukuroi and in 1873, the Akiha temple was proclaimed to be the “Akiha Shrine”. The shrine was regarded as a prefectural shrine under the State Shinto system. Most of the structures of the burned down in 1943, and were not restored until 1986. The shrine has a small museum preserving remaining artifacts, including a number of swords presented as offerings by Imagawa Nakaaki, Takeda Shingen, Toyotomi Hideyoshi and Katō Kiyomasa.
