Mt Ena is a very sacred mountain from ancient Wosite times. The region around Mt Ena contains some important sites in the story of Amateru Amakami. Isanami gave birth to Amateru at the place now known as Chiarai Jinja (lower left side of the map). Chiarai, chi-arai, refers to washing the blood of Amateru’s birth. His placenta (ena) was buried at the top of Mt Ena for safekeeping and for his protection in life. There is a shrine at the peak of Mt Ena, and another at a lower elevation directly to the west. See the map below.

Looking far to the east, we see Achi Shrine Okumiya. This is the burial place of Achihiko Omoikane, Amateru’s brother-in-law and Hiyominomiya, master of the solar calendar. In this region between Mt Ena and Mt Kasagi to its west, many megaliths can be found. There is a distinct possibility that these megaliths form a system for the determination of a solar calendar from Jomon times roughly 5,000 years ago. Maruyama Jinja in the upper left of this map is one possible solar site. Thus we decided to publish this Mt Ena post on this — Iwakage’s — blogsite.

Mt Ena is part of the Kiso mountain range of the Central Alps and it straddles the border between Gifu and Nagano prefectures at the cities of Nakatsugawa in Gifu and Achi in Nagano. Mt Ena is one of the 100 famous mountains of Japan. Mt Ena can be written 恵那山 or 胞衣山, where both 恵那 and 胞衣 are read ena. When written as the latter, the word 胞衣 means placenta or afterbirth. At the peak is the honsha main Ena Jinja shrine, the Okumiya (deep sanctuary). There are six sessha auxiliary shrines in the vicinity.

Ena Jinja 恵那神社

Ena Jinja is an ancient shrine whose establishment is unknown. It occupies two sites, the Okumiya being at the top of Mt Ena. The more accessible maemiya shrine is in the foothills due west of Mt Ena. A drive up from the valley, alongside tumbling streams, takes us to the parking lot of the shrine where there’s more water gushing out of the slope. We first admire the panoramic view to the west.


We immediately spot the first torii which is facing the parking lot. We pass under the torii and climb the steps to the landing. There is another flight of steps, making a right angle, to the prayer hall above.

The enshrined kami are Isanami and Isanagi (the parents of Amateru), and Amateru’s advisor the wise Amenokoyane, all very important people in the Wosite documents. Also enshrined here are Toyoke (Isanami’s father and Amateru’s grandfather), Yama-kami, and Tenhaku. To the left and right in front of the haiden are two splendid male-female sugi trees. Presumed to be between 600 to 800 years old, they are a Gifu prefecture natural monument. In the back of the haiden is the nagare-zukuri style honden.

The peak of Mt Ena must be behind the prayer hall, but we can’t see it for all the trees.

When we turn around to go back down, we note that the prayer hall shown above is facing west 240 degrees. This is the direction to the winter solstice sunset! Here is where the winter sun will set: at the notch in the flat mountains beyond.

On the way down, we pass newly planted rice fields and the rushing Nakatsugawa River.


Here is a final view of the splendid — and sacred — Mt Ena.
