Beginning of Winter at Kanayama Megaliths

There are several new posts at our Japanese counterpart of the the Kanayama Megaliths blog. On 10/23, sixty days before winter solstice, a group trekked up Higashinoyama to see the sunrise. Above is the photo, and this is the 9-meter long stone on which the observer sits.

The group came down the mountain and went to Iwaya-Iwakage. Here is the sunlight entering the chamber at 12:50pm.

On 10/24, this striking pattern appeared on the Sekimen-ishi.

We remind you of the similarity of the Kanayama calendar with the Egyptian calendar. On this date, the rising sun shines into the stone room at the end of the Great Temple of Abu Simbel. Also, the sun rises from the Sphinx on the causeway to the great pyramid of Khafre.

We hope that you have enjoyed these reports of the solar calendar of the Kanayama Megaliths, still operating after 5,000 years!

Iwaya-Iwakage: Sixty Days Before Winter Solstice 2018

Sunlight entering Iwaya-Iwakage on 2018.10.23 at 13:00

 

The sixty days before winter solstice, observed at Higashinoyama in early morning, was confirmed in Iwaya-Iwakage at around 1pm on October 23, 2018. There were clouds in the sky around that time, and cheers broke out whenever the spotlight on Sekimen-ishi stone appeared. Here are photos of the large spotlight at various times when it appeared (12:56, 13:05, and 13:09). Since we are facing north, to us the spotlight appears to move from west to east. The last photo shows the light has reached the right-hand edge of the Sekimen. Branches of trees have cast some shadows on the stone.

Higashinoyama: Sixty Days Before Winter Solstice 2018

2018.10.23 Higashinoyama sunrise

This sunrise photo was taken by Chika-san the morning of 2018.10.23 at 09:44:25 on Higashinoyama. On the right of the sun is S Stone, on the left is the 9-m long R stone which points in the sunrise direction.

This observation heralds the approach of the winter solstice sixty days hence. The sun will occupy the same position on February 20 as it heads north for the summer. These two dates, 10/23 and 2/20 which bound winter, together with the two summer dates of 4/22 and 8/20, divide the sun’s zone in the sky into four equal parts.

Furthermore, when the winter and summer solstice dates are included, we obtain the six-season Kanayama Solar Calendar.

Thirty Days After Summer Solstice

d1706b89

At Senkoku-ishi, the dashed spotlight tells us in a dramatic light-show when it is thirty days before and after the summer solstice. The Kanayama Megaliths Japanese blogsite has posted photos from this year’s July dashed spotlight observations. There were torrential rains in Western Japan in preceding days, followed by 39 C = 103 F high temperatures. Yet, many people came who had seen the NHK special on the Kanayama Megaliths just a couple of days prior.

The dashed spotlight could be seen for five days, growing stronger, then thinner. Even on the final day, we could see four dashes.

For other photos and the report in Japanese, please click on the above underlined link. As Shiho Tokuda reminds us in this translation from her blog:

“Because the year is not exactly 365 days, the appearance of light slightly changes even for observations on the same day every year. It is repeated approximately every four years. Although it is related to the leap year, it is difficult to determine a leap year by this observation because the movement of the sun every day as seen from the earth is small. ”

For a more accurate method for leap-year determination (in October 2019, for instance), the Kanayama Megaliths has the leap-year observation in Iwaya-Iwakage.

Summer Solstice 2018

June212018by KS

Kazuo Sugisaka made this report on this year’s summer solstice at Kanayama Megaliths. He arrived there a day early, June 20, and it was rainy all day. The next day, summer solstice day, it was cloudy during the morning and it seemed doubtful that the sun would come out. Fortunately, it turned sunny during the afternoon, and by sunset the sun could be seen sinking between two megaliths at Senkoku-ishi site. Summer solstice is a marker date on the Kanayama Solar Calendar. It marks the beginning of the 60-day late summer period.

Last year, we noticed a rather unusual flower blooming amongst the megaliths. This year, Sugisaka-san took this photo. It was identified as Cyrtosia septentrionalis, called tuchiakebi in Japanese. It is a member of the Orchidaceae family.

60 Days Before the Summer Solstice

From Friday, April 20th to Sunday 22nd, 2018
The above photo of the whole area, showing the Iwaya-Iwakage cluster on the left and the simulator building and the Senkoku-ishi grouping on the right, was taken from Highway 86 early in the morning of April 20.  Kanayama Megaliths blog has posted a new report dated April 26, 2018.   It is about the observation of 60 days before the summer solstice in the solar calendar of the Kanayama megaliths. It is the sunlight observation that tells the beginning of summer at the April 22 milestone date of the Kanayama Six-Season calendar.
At 6: 54 in the morning, light begins to stream from the top mountain. Summer observation is mainly at Senkoku-ishi. Looking at the position where the sun rises from the megalith, we see the sun just ascending from the mountain in the east at the Higashinoyama group. Now it’s past seven, and the light begins to reach Iwaya-Iwakage which is located somewhat higher than the Senkoku-ishi.
Then light begins to penetrate into the grotto of Senkoku-ishi. Around 7 a.m., sunight starts to shine on every single megalith. Although it starts out rather chilly, when the sun comes out, we feel the air of summer already.
Today Kobayashi-san is here, and there is a television interview going on. Kobayashi-san is standing in front of the shadow on Senkoku-ishi. this shadow is cast by the megalith in the lower right photo, below, on the morning of April 22.
As the sun rises higher, the grotto is illuminated, and the triangular face is very bright. On May 21, this face will be adorned with dashes of sunlight.
