Kanasana Shrine (金鑚神社)

Kanasana Shrine has no honden — no main sanctuary building. Instead, the object of worship is Mount御嶽山 (Mitsumine) itself, rising directly behind the worship hall as a pyramid of exposed rock and ancient forest. This is one of the oldest and rarest forms of Shinto practice: direct mountain veneration, where the entire mountain functions as the deity’s body. The shrine’s name, Kanasana, means “metal glitter” — a reference to the iron ore deposits that made this mountain sacred to metalworkers and swordsmiths who saw in its stone the raw material of civilization itself.

Kanasana Shrine was established in the early Heian period, though worship at Mount Mitsumine predates written records. The shrine served as the spiritual center for the ancient Musashi Province metalworking communities, who mined iron from the mountain’s slopes and understood the extraction of metal from stone as a sacred act. By the 12th century, Kanasana had become one of the six major shrines of Musashi Province. The current haiden (worship hall) dates to the Edo period, but the practice of worshipping the mountain directly — without an intervening structure to house the kami — preserves a form of Shinto that existed before permanent shrine architecture. The mountain itself was declared off-limits to ordinary climbing until the Meiji period, reserved exclusively for ritual ascents by shrine priests.

Amenohoakari no Mikoto is the primary deity, a grandson of Amaterasu and divine ancestor of metalworking and agriculture. He is credited in the Nihon Shoki with bringing agricultural tools and metal implements to earth, transforming human civilization. At Kanasana, he is worshipped specifically as the kami of metal and mountain, embodied in the iron-bearing rock of Mount Mitsumine. The shrine also venerates Susanoo no Mikoto, the storm god associated with both destruction and the forging of the sacred sword Kusanagi, linking divine violence to creative transformation through metalwork.

The shrine’s founding legend tells of a metalworker named Kanasana who, in the 8th century, had a vision while attempting to extract iron from the mountain. Amenohoakari appeared to him not as a figure but as golden light emanating from the stone itself — the “metal glitter” that gave the shrine its name. The kami told him that the mountain was not merely a source of ore but the deity’s physical form, and that to mine it without reverence was to wound the god. Kanasana established worship at the mountain’s base and taught that metalworking was an act of partnership with divine stone. Another tradition holds that the mountain’s pyramid shape is the result of Amenohoakari descending from heaven and striking the earth, the impact forming the peak as a permanent marker of divine contact with the human world.

The shrine complex consists of a haiden (worship hall), kaguraden (sacred dance stage), and several auxiliary buildings arranged at the mountain’s base, but conspicuously lacks a honden. Worshippers face directly toward Mount Mitsumine’s rocky summit visible through the trees behind the haiden. The haiden itself is built in the gongen-zukuri style with elaborate wooden carvings dating to 1762, featuring dragons, phoenixes, and kirin — mythical creatures associated with divine authority. A torii gate marks the transition from profane to sacred space, but beyond it lies only forest and mountain. The approach path is lined with massive cedar trees, some over 600 years old, and passes stone lanterns donated by metalworking guilds during the Edo period. The iwakura (sacred rock) that serves as the direct worship focus is a natural stone outcropping at the mountain’s base, unworked and unmarked except by centuries of prayer.

• Reisai (Annual Grand Festival, April 15) — The main festival featuring kagura performances and processions of mikoshi. Traditionally, metalworkers would present newly forged blades and tools as offerings.
• Hatsumode (New Year) — Thousands visit for first prayers of the year, seeking blessings for industry and craftsmanship.
• Niinamesai (November 23) — Harvest thanksgiving ritual that also honors Amenohoakari’s dual role as agricultural deity.
• Tsuitachi Mairi (Monthly First-Day Worship) — Regular morning rituals on the first of each month, maintaining the ancient practice of mountain veneration.

April, during the Reisai festival, offers the fullest expression of the shrine’s traditions with kagura and ritual processions. November brings spectacular autumn colors to Mount Mitsumine’s forest, and the contrast between vermilion shrine buildings and golden foliage creates the shrine’s most photographed season. For experiencing the mountain-worship aspect directly, visit on a clear winter morning when the peak is visible in sharp detail through bare branches. The shrine is least crowded on weekday mornings, when the ancient relationship between mountain, metal, and reverence can be felt without distraction.
