The Amatsu and Nou Hakusan shrines have such strikingly similar architectures, namely their thatched roofs, that we are reporting them sequentially. They are both in the city of Itoigawa (糸魚川), Niigata-ken (新潟県), and they both enshrine Nunakawa-hime, the heroine of this region, plus other kami of interest to those who study the Woshite documents.
Amatsu Jinja 天津神社
Amatsu Jinja, ichinomiya of Echigo (Niigata), is a few minutes walk from Itoigawa station. When you arrive at the site, cross over a bridge and turn to your left to the temizuya, then resume your path. You are taken to a higher level so you are on a yama. You make a final left turn and suddenly the striking haiden prayer hall comes into view on your left. The hall has an immense thatched roof. There are three altars in the haiden: 奴奈川神社 (Nunokawa Jinja)、天津社 (Amatsu Sha)、住吉の扁額 (Sumiyoshi Hengaku).
The primary gosaishin of Amatsu Jinja is Amatsu-hikohikoho-ninigi-no-mikoto, or Ninikine. Ninikine (Ninigi) is enshrined in several sacred sites in this Hokuriku area of Niigata and Toyama, far from his home area of Kansai. Ninikine is Wakeikazuchi, kami of Kamigamo Jinja in Kyoto. Also enshrined here are Amenokoyane no Ookami and Futodama no Mikoto; both are mentioned in Aya 20 of Hotsuma Tsutaye. Amenokoyane was Tsurugi no Tomi to Amateru. He was the author of Mikasafumi.
The Amatsu honden is detached from the haiden and is in the back with other hokora. In the background of the haiden photo, you can see a row of hokora. The one that is visible in the photo is Nunakawa-hime Jinja, left of the honden. Nunakawa-hime is a popular heroine of Itoigawa and she is regarded as kami of jade found in the area. There is a dragon carved on the lintel, closeup photo.
On the right of the honden is the 聖神社 Hijiri Jinja (聖 hijiri means sacred).
Next to it is a compound of small stone hokora, and they have the great charm of age.
