The megalith that shapes the spotlight

Photo by IR.

The spotlight that shines into the chamber of Iwaya-Iwakage is shaped by the megalith that we see on the right of this photo. It somewhat resembles a duck, and the “head” is the all-important governing tool. It is amazing what different shapes the spotlight can take during the course of a year.

The slope of the site

Photo by IR.

This photo shows how the ground is steeply sloped as we look toward the east. Trees like those in this scene have been felled so that they no longer block the spotlights in the megalithic chambers. The simulator is seen on the right, and in the center is the Senkoku-ishi.

Iwaya-Iwakage on the slope

Iwaya-Iwakage sits high on the slope, facing the south. That is why it is such a good site for winter observations. To the far right of this photo can be seen a part of the Senkoku cluster of megaliths. There is a path connecting the Senkoku to the Iwaya-Iwakage.

North-star observing megalith

Photo by IR.

A visiting group gathers at the megalith shaped like a pyramid. The inclined “front” face has a slope of 35 degrees to the north. By sighting along this plane to the apex, we are able to see the north star at night. In the background is the curved roof of the solar-direction simulator.

Megaliths seen through the trees

When you arrive at the Iwaya valley site, you park on the road next to the stream. This may be one of your first views of the megaliths. These are the Senkoku megaliths as seen from the east. The Iwaya-Iwakage megaliths are further west and further up.
