October 16, 2017. This is the report of our visit to the Asadori Myoujin shrine. We have reported that a Himukae winter festival takes place here on winter solstice mornings to welcome the sun. Our specific purpose was to study the layout of the stones which are said to mark directions to sunrises on solstices and equinoxes.
We visited Asadori Myoujin in the rain. The site is raised slightly above the surrounding plain. We parked in the lot with a sugi grove to the southeast. We turned to face the torii, and we could see that the path led straight to a second torii on the grounds. This would be the path of the sunlight on winter solstice morning. The azimuth angle was verified by our analog and digital compasses.
We pray at a small hokura in front of a mound. See photo at top. Directly in front of us is the sun-stone draped in shimenawa. Beyond it we see the top of another stone. Here is a close-up so that you can see the stone behind the shimenawa sun-stone.
Distance measurements were taken with a laser measure. The distances found are: from second torii to hokura base, 5.1m; to the sun stone, 11.0m; and to the winter solstice stone, 19.0m.
It has been reported that there are four or five stones lined up in a row, the one furthest west of the winter solstice stone would be the summer solstice stone. We are unable to see the other stones due to the topography and the growth of plants, plus the area behind the hokura is cordoned off with bamboo. We would have liked to take measurements of the distances between the stones. Unfortunately, we could not do it. So we will have to return another time when there is less vegetation and we can see the other stones.
This is the alignment on winter solstice morning: sunlight streams through the first torii, the second torii, the hokura, the sun-stone, and the winter solstice stone. Here is the view looking from the inner torii to the place where the winter solstice sun will rise.
We noticed that the rising winter solstice sun would be blocked by the grove of tall sugi on the other side of the parking lot, in the background of the above photo. Perhaps the winter Himukae festival takes place after the sun has cleared the trees.
