Early December at Kanayama Megaliths

金山巨石群 12月初め  Kanayama Megaliths Early December

12月 2日(金)   December 2 (Friday)

Fine weather today. Visitors in the morning and afternoon.


The 10 o’clock tour is recommended when visiting Kanayama Megaliths in winter because the morning sun emerges from the mountain around 10 am. The cooling of the previous night still continues into the morning.


From the lower megalith site (Iwaya-Iwakage and Senkoku-Ishi) we can see the sun  shining on Higashinoyama Eastern Mountain at around 9:15 in the morning.


Here at the lower megalith site, it is still cold. However light is beginning to hit the mountain in the back of the lower site.

On this day there were four people in the group from 9:50 to 12:30. Winter showtime at Iwaya-Iwakage: about 10 o’clock, the morning sun gradually enters inside. A movie would allow you to visualize the impression. A mysterious feeling seems to drift in the air like when you’re in a snow scene.

This is a picture taken at 11 o’clock in the morning on 29 November. The winter sun rising from the mountain is in a low position.   

In winter, sunlight from the south streams in so as to fill the center of Iwaya-Iwakage chamber. Because the light is lower than the sloping face of 40 degrees of the F stone, you can see from these two photos that the light is striking the face. Winter light shines into Iwaya-Iwakage.

夕  Evening

 December 2 (Friday) evening, one French visitor, Kobayashi and Tokuda guiding.

6-5fb8974aThe French visitor asked to buy three copies of the Kanayama Megaliths Solar Observation Guidebook so as to introduce the megaliths widely in France. He exclaimed that the Kanayama Megalith group is “rare and unique in the world.” Immediately after he got off the Kanayama station and we met, we entered the theme of the subject and discussed the issue even before having coffee at the “Minoya” shop in front of the station. We headed for Kanayama Megaliths in an excited state. He said that the scale is bigger than he had expected. It is awesome, awesome! And he started to develop his own theory.

France is famous for the Carnac standing stones, and he asked if the Kanayama Megaliths hold the same view as Carnac that connects with the ancient Egyptian ruins. An archaeological astronomical view that used to be seen as a blind spot is becoming a subject to study in France as well. 






The climax of winter light is at 4 o’clock in the evening. The sun just before sinking into the mountain will show itself between megaliths. It’s been a fine day all day.

December 2nd is already well into the season that it can be regarded as having almost the same light as the winter solstice. 

Even though the cold of the season will increase, the power of this winter light to human beings is immeasurable. This light can be freely experienced until around February 20th. 


This year, the plan is to climb Higashinoyama for the winter solstice observation on December 21 (Wednesday). Please meet at the Iwaya-Iwakage megaliths at 7:30 in the morning. Please make a reservation to confirm the number of people accompanying you.

The winter solstice observation meeting lasts three days from 21st to 23rd. It takes place around 10:00 am until around 4:30 pm. Please use the Kanayama Megaliths Guidebook  http://wp.me/p6j8iM-8n.



Beginning of Early Winter at Higashinoyama


The Japanese Kanayama Megaliths blogsite has just made two new posts about the beginning of the winter season (Early Winter in the Kanayama Solar Calendar is the approximate sixty-day period prior to the winter solstice). Here is an excerpt from the post dated 2016.12.04, with permission. The original post in Japanese is:



金山巨石群 冬期の始まり   Beginning of Early Winter at Kanayama Megaliths

In the Kanayama Megaliths solar calendar, wintertime begins on about 10/23. This is similar to the calendar of ancient Egypt.

朝の観測 Morning observation

For the first observation of the Early Winter season we went mountain climbing to Higashinoyama (Higashi-no-yama, Eastern Mountain) megalith group. This year at 8:30, a total of five people departed from Iwaya-Iwakage site. Here are some photos taken when we reached the peak.

When reaching the top ridge, a little down the slope on the south side, two megaliths of 9 meters long appear side by side. This is the Higashinoyama megalithic group. The R stone that observes the morning sun of the winter solstice 12/22 is visible in the center of the photo above. The S stone can barely be seen in the left rear. Below is a photo of observation at S stone.


This is the day 10/22 for the observation at S stone. We observe from the bottom of the stone wall, as shown above. Shown below is a third megalith which is under stone S. 


The sunbeam appears on that line today, 60 days before the winter solstice. It is seen only within 10 minutes from around 9:45. After that the sunbeam will not reach here until February 20 next year because the sun altitude goes down day by day until the winter solstice. In other words, when light comes out again here, it will tell the end of about 120 days of winter, and we will know that the arrival of spring will come after 30 more days.


This day was the best observation day. Creating a calendar with a combination of giant stones and sun tells us that there was a universal idea in ancient times. This is beyond the imagination of modern people.


Iwaya-Iwakage October 23, 2016


October 23 is a special date at Iwaya-Iwakage. It is 60 days before the winter solstice, and it marks the beginning of the winter observation period. As usual, we were concerned about the weather because five days before the 23rd we were still having rainy and cloudy skies. We were cheered when 10/19 dawned bright and clear. Inside Iwaya-Iwakage, Shiho Tokuda is showing us the Sekimen stone which will be the surface on which the spotlight will shine. Amazingly, the Sekimen is actually not separate from Stone F; it is sculpted out of the same rock! Its forward face, although buried deep underground, is parallel to the 40-degree face of Stone F. You can glimpse a bit of that face in the space beneath Sekimen in some of the spotlight photos.


In the next photo, Ms. Tokuda is pointing to the triangular spotlight which, in four days, will illuminate the rectangular face of Sekimen. It’s hard to believe, isn’t it?

dsc02808The exterior shot shows the interplay between Stones F and E which will form the shape of the spotlight. The complicated contour of Stone E is what, in part, causes the shape of the spotlight to change depending on the position of the sun.


The next day, we stop by the Solar Calendar Simulator building. From the south side, we see the slits that simulate the gaps of the megaliths that allow sunlight to form beams inside of Iwaya-Iwakage. The bottom-most slit is, of course, for the winter solstice sun. Inside, there are five planks that are oriented to the direction of the sun on five special dates of the year. From left to right, the directions correspond to the sun’s elevation on 6/21 (summer solstice), 8/20 (sixty days after summer solstice), 9/23 (autumn equinox), 10/23 (sixty days before winter solstice), and 12/22 (winter solstice). Of course, the sun reverses its path and will be at the 10/23 position again on 2/19, at the equinox position again on 3/21, and at the 8/20 position on 4/22, before arriving at summer solstice once again. See Basic Calendar chart on page 21 of the Guidebook, previous post.

The sun’s beam is shining on the bottom of 10/23 screen (because it is still three days before the 23rd). You can see it better in the closeup photo.


Next, we show the spotlight on the real Sekimen at 12:50 on 10/20. See how the actual spotlight is low on the stone as well as on the simulated stone. We also show you the gap through which the sunbeam enters, and it is evident that the “roof” formed by Stone F is not resting on Stone E. This is another amazing feature of the megalith arrangement.




The next two days were again cloudy, and on 10/23 there were clouds in the sky. The sun broke through the clouds intermittently, and we were delighted that we could obtain these three photos at 12:46, 12:48, and 12:54.


We dub the sixty-day period before the winter solstice, Early Winter. Our spotlight observations announced that Early Winter has officially begun!
