Hida Koku and Birth of Hida Kuni Jomon Dynasty


Iwaya-Iwakage,our sister site, has just posted a series of articles that begins:

Birth of Hida Kuni Jomon Dynasty

The land of Hida, where the Kanayama Megaliths are located, may not be so well known historically as other parts of the country such as Kyoto and Nara. And yet its history stems from the Jomon Period, 12,000 BCE to 300 BCE. In the article presented below, the unnamed author declares that there are many folkloric sources that reveal the possibility that Hida was the  place where civilization began, ultimately leading to the modern nation of Japan.


Miyagi’s Hakokurayama 函倉山 Pyramid Mountain

dsc00564-closerIn October 2013 we had the chance to visit some pyramid mountains in Tohoku. Previously visited were Kuromanta yama in Akita/Aomori, Himurogatake in Kyoto-fu, Kuraiyama in Gifu-ken. This report is about Hakokurayama (Hako-kura-yama) 函倉山  and two other posts are on Taihakusan 太白山  in Sendai-shi, and Togariyama  尖山  in Toyama-ken. Our visiting Hakokurayama and Taihakusan was based in part on Yo Hamada’s Pyramid Mountains Hakokurayama. 函倉山

In another post, we discussed some of the alignments of Hakokurayama with the winter and summer solstice rising and setting sun.

From Sendai station by car, it took only 30 minutes to get to the Rikuzen-Shirasawa train station which we had read about. We started shooting pictures of the mountains that we could see from there, but we weren’t sure which was it. We guessed it would be the mountain to our right. We started driving around that mountain counter-clockwise past the school, and we knew we were close. We parked at the water pumping station. We walked around two sides of the mountain. There are a creek going around the mountain and several ponds. The pond in the photo below is very lovely. No doubt there are springs here.

If it is a square pyramid as this contour map indicates, … Wow! Note the flat top. There was a hatake and plants were growing well – pyramid energy! That there is so much water must be significant – it may be a water source. The station must be pumping water to Sendai-shi.



The Pyramids of Suzuki Akira

and Kuromanta by Suzuki Akira, 2006.

Suzuki claims that the following six mountains are pyramids in the manner of Kuromanta. His two criteria are having a sacred area on the mountain top, and having alignments to the solstice sunrises and sunsets.

1. Higashitaniyama (Aichi, Nagoya)

2. Miwa (Nara, Sakurai city)

3. Moyamoriyama (Akita, Lake Tazawa city)

4. Senganmori (Fukushima, Iino town)

5. Kasagiyama (Gifu, Ena city)

6. Han no Kiyama (Gifu, Yamaoka town)

The list in Japanese:








In Suzuki’s Kuromanta book, he describes other pyramids. In Sendai, Togamiyama was called Tongariyama (Togariyama). It is not a pyramid.

To the east of Togariyama i Hakokurayama [page 337]. Suzuki says it is a square pyramid, as is seen from a contour map. Although there is no shrine, the top is flat. It has a petrograph megalith facing the direction of the WSSR.

Hakokurayama itself is aligned with a petrograph megalith in the direction of the SSSR, and that megalith is facing the WSSR.

On top of Maeyama, there is a jinja from which one can see Hakokurayama in the direction of SSSS.

North of Hakokurayama is the 10,000 year old Nogawa Iseki ruins. It was built from the very hard stones from Mogamigawa in Yamagata-ken. Did the Yamagata Jomon build Hakokurayama?


Sakai’s List of Japanese Pyramids

Sakai Katsutoki published a book, The Pyramids of Japan, in 1934. Here is his list of 12 pyramid mountains.

  1.  葦嶽山/広島県     Ashitake Yama, Hiroshima
  2. 尖山/富山県     Togari yama, Toyama
  3. 位山/岐阜県     Kuraiyama, Gifu
  4. 五葉山/岩手県     Goyosan, Iwate
  5. 大石神/青森県     Oishigami, Aomori
  6. 黒又山/秋田県     Kuromanta yama, Akita
  7. 三瓶山/島根県     Sanbin yama, Shimane
  8. 剣山/徳島県     Tsurugi san, Tokushima
  9. 日室ガ嶽/京都府     Himurogatake, Kyoto fu
  10. 皆神山/長野県     Minakami yama, Nagano
  11. 千貫森/福島県     Sengan mori, Fukushima
  12. 八幡山/兵庫県     Hachiman yama, HyogoSakai pyramid map_0001

A Japanese pyramid is said to have three characteristics.

1.  It is triangular in profile. While Egyptian and Mayan pyramids have square bases, Japanese pyramids usually have a circular base although there are square ones as well.

2.  At the mountain peak are iwakura, rock seats where kami are said to descend. These are not only large stones, they are megaliths. They may be arranged in different ways. For example, some are menhirs, others are table-formed, others are stone circles.

3.  Since the iwakura are sacred, there is usually a worship location to pray to the kami of the mountain.

We believe that before there was Shinto, or even Koshinto, the spiritual practice of the ancient people was to connect with the universe on mountaintops. Later, when shrine building were erected, they were situated with certain alignments, east-west being a favored one. Also favored were solsticial alignments. At the latitudes of the archipelago, the directions would have been 30 degrees north and south of east.

Kuraiyama, Sacred Pyramid Mountain

Kuraiyama, 36 degrees N, 1529 m, is said to be a pyramid mountain. Moreover, it is claimed by the Takenouchi Documents as the site where extra-terrestrial ancestors touched down. Its name, crown, refers to its regal status in prehistoric annals. More exactly, ‘kurai’ means ranking, and this is the number one ranking. The ichi-i (again, number one) tree grows here. From the wood is made the mace of the emperor.

We have learned more about Kuraiyama since we began this post. See ‘Roots of Japan.’

Kuraiyama has been rudely treated by being partially denuded to accommodate a ski resort. However, it is said to still have a number of interesting megaliths on top. Click on the map to see it enlarged. Eerie stories have circulated about mysterious lights and even more mysterious strangers.

Here’s more about the megaliths. Megaliths were brought to the mountain by the leaders of the people of Hida. Generations of such leaders have been buried around these boulders. This accounts for why Kuraiyama is such a sacred mountain. Its shrine is the Minashi Jinja, q.v.

Toyouke Daijinja in Tango

Motoise Sansha

The Motoise Sansha, are the three shrines of Motoise: Motoise Naiku Koutai-jinja, Motoise Geku Toyouke Daijinja, and  Amano Iwato Jinja. Motoise means that these shrines were prior to the founding of the Ise Jingu shrines.

This post is about Toyouke Daijinja, one of the Motoise Sansha listed above.

DSCN7633     DSCN7642  DSCN7646

We visited Toyouke Daijinja in April 2013. Toyouke Daijinja is an old village shrine in 京都府 Kyoto Fu, 福知山市 Fukuchiyama Shi, 大江町 Oe Machi, Amata. It is also called Motoise Geku Kotai Jinja.

Koutai Jinja (Toyouke Geku) is the okumiya inner shrine of Motoise Naiku/Geku. Densho shrine literature says that Sujin Tenno in his 39th year, 59 BCE, built it. [Note: JTC’s Hotsuma site says in Aya 33 that Mimaki/Sujin went in the 7th year to Hinumanai Jinja to pray. That would make it 58 BCE.] Before that, there was an omiya in Sakurai, Nara. Sujin’s ancestors told him to have another place for omiya. He went to Tanba and built this jinja. After four years he went back to Yamato, to Sakurai Kasanui.

I believe that this jinja is connected to Toyoke Kami through the Manai Jinja and Hinumanai Jinja of Mineyama. I would be curious to see how they are located geographically.


Motoise Sansha, Naiku, Himurogatake, and Amano Iwato Jinja          DSCN7584

Location of Motoise Naiku Kotai-jinja Shrine: 217 Naiku, Oe-cho, Fukuchiyama City, Amano Iwato-jinja Shrine: 206-1 Butsushoji, Oe-cho, Fukchiyama CityMotoise Geku Toyouke-daijinja Shrine: 60 Amadauchi, Oe-cho, Fukuchiyama City – A 10-minute walk from Oe-Yamaguchi-Naiku Station on the KTR Miyafuku Line. The other shrines are Motoise Geku Kotai-jinja Shrine / Amano Iwato-jinja Shrine.

Naiku Kotai Jinja is dedicated to Amaterasu Omikami. DSCN7585  DSCN7594  DSCN7606  DSCN7608

These paragraphs below include comments from Yoshida San’s pamphlet about the Motoise Sansha, the Amano Iwato Jinja, and the pyramid mountain that lies near it. The urasando back promenade of Naiku goes  to Amano Iwato Jinja which he considers the okumiya of Naiku. On the way, you see the triangular profile of Himurogatake mountain. On summer solstice, the sun sets at the mountain top.

This mountain, Himurogatake, is also known as Iwatoyama, Shiroyama, Hihura gatake, Himurotake. It is a sacred mountain. On top is a large iwakura, it is said. Stones are placed like zoukebutsu, man-made buildings. The east side of the mountain (facing us) was a sacred place where no one was allowed to enter.

Takasoko Shiroyama is a mountain across from it, and it is not a pyramid. Takasoko jyo is a castle on imperial land. An Amakami (Koutai jin) has his remains here, legend says. Could it be Amateru?

DSCN7621     We continue on to Amano Iwato Jinja. At the torii, the stone steps are uneven and steep. It is next to the Miyakawa (Isuzu kawa). Amano Iwato Jinja stands on a kyogen, a megalith, although it could be simply the outcropping of the mountain. It’s hard to tell by looking from the bottom. The shrine is so high above that I could only leave my offering on a rocky ledge.DSCN7629   DSCN7625
