Togakushi Village and the nearby Togakushi Shrine are situated in the north of Nagano within the Joshinetsu National Park, a 45-min drive from Nagano City. This volcanic area is at an altitude of 1,200m at the foot of the two volcanoes, Mt Togakushi 戸隠山 (1,904m) and Mt Iizuna 飯縄山 (1,917m).
Deeply steeped in mystery, Togakushi is part of the Ama-no-iwato Hirake myth, the opening of the Heavenly Cave Door. Ama-no-Uzume danced and Tatikarawo (Tajikarao) opened the Amanoiwato, and the door flew to Shinano/Nagano. Togakushi means hidden door.
Togakushi Jinja 戸隠神社 N 36.76, E 138.07, Alt 1289m
Togakushi Jinja consists of five shrines at three shrine locations: the lower, middle, and upper shrine areas. The lower area has shrines 宝光社 Hōkō-sha (Treasure of Light) and 火之御子社 Hino-miko-sha. The middle site has the 中社 Chū-sha (Middle Shrine). The upper area consists of the 奥社 Oku-sha (Deep Sanctuary) and 九頭龍社 Kuzuryu-sha.
Togakushi Jinja may have originated at Achi Jinja in southern Nagano. Togakushi’s Chū-sha and Achi Jinja both enshrine Omoikane.

Oku-sha, the oldest of the five, is the sanctuary of the shrine high up in the mountains. The Oku-sha enshrines Amateru and Tatikarawo (Tajikarao). The map shows the long path from the first torii to the Oku-sha. We went as far as the Zuishinmon Gate. The rest of the way would be all uphill. This site is considered a power spot and is immensely popular with those visiting the shrine as well as the walking-impaired who could enjoy the smooth walkways through nature.
Genbu.net has this to say about Oku-sha. The original kami of this sha were nine dragon-kami who dwell in rock caves. Dragons are associated with water and will relieve tooth decay problems if one prays to them. The legend of Tajikarao was introduced later.
Chū-sha 中社 Center Shrine
Chū-sha means middle or center shrine. It is physically located in the center of the array of five Togakushi shrines. The second Togakushi sha (after Oku sha) to be establlished was Hōkō-sha, and Chū-sha was created midway between the two. Chū-sha enshrines the kami Omoikane. It is commonly said that Omoikane is “the kami who organized the kagura dance performance in front of the cave”. We have yet to find this reference in the Hotuma Tutaye Wosite document. However, the document tells us that Omoikane is the father of Tatikarawo who opened the cave door. Also known as Achihiko in Wosite history, Omoikane is a great-grandson of Toyoke Takamimusubi and he held the post of Hiyomi-no-miya, Master of the Solar Calendar, for Amateru. Omoikane is generally considered to be a kami of wisdom. The full story of Omoikane can be found in the Wosite documents.
Hinomiko Sha 火之御子社, 日之御子社
Hinomiko Sha enshrines Ame-no-Uzume, the female kami whose dancing lured Amateru out of the cave. Also enshrined are Takamimusubi, Oshihomimi (son of Amateru), and his daughter Takuhatachichihime. In Wosite history, the best-known Takamimusubi is the grandfather of Amateru. It is said that the name Hinomiko refers to a kami of fire (hi), which seems rather out of place here. If the word Hinomiko were written with the character for sun (hi) instead of fire, 日之御子社, Hinomiko would mean the son of the kami of the sun, namely Amateru. This would make more sense.
Genbu.net has a comment on the name and the enshrined kami. Based on Oku-sha’s kami Tajikarao and Chu-sha’s Omoikane, Genbu says that Hinomiko sha’s kami Ame-no-Uzume is in error and she should have been named elsewhere.
Hōkō-sha and Kuzuryu-sha
We were unable to visit two of the five Togakushi sha. Hōkō-sha enshrines Ama-no-Uwaharu (another son of Omoikane) and a guard in the tenson korin myth. Kuzuryu Jinja Nine Dragon Shrine enshrines a water kami known as Kuzuryuu no Ookami from ancient times, or Benzaiten from later Buddhist times. In Japanese thought, dragons are associated with water, as is Benzaiten. We missed these two because we were unable to park the car at the Hōkō-sha, and the other is located at the top near Oku-Sha.
Kuzuryusha sits next to Okusha, and has been the central deity for the Togakushi worship as the local deity since the old time. As the deity who presides over the water, it is worshiped by the people engaged in agriculture in the wide area along Torii, Kusu and Susobana rivers, as well as the Echigo region, which is connected through the underground water.From http://en.nagano-cvb.or.jp/modules/sightseeing/page/376
Though the date of foundation is unknown, it was enshrined as the local deity before the enshrinement of Ame-no-tajikarao-no-mikoto. It is worshiped for its divine virtue of realization of wishes. It is also worshiped as the god of [dental] caries as well as of matchmaking.
The comment about the original deity of Togakushi being a dragon-water being can lead one to regard the Togakushi shrines as being ancient sacred places honoring kami of nature such as water and fire. Later, historical figures were added, and even later some Buddhist elements were incorporated. There is still much that remains a mystery about Togakushi.
