Winter Solstice at the Kanayama Megaliths

The Kanayama Megaliths from the Jomon period have been following the path of the sun in the sky for thousands of years. Thirty observations are made per year to determine the super-accurate solar calendar, an astronomical calendar. One of the most important observations is shown above. The photo was taken by Chika-san at Higashinoyama on December 22, 2019 when the sun rose above the neighboring mountains, and appeared directly ahead of the 9-meter long megalith.

Civil and Astronomical New Years

In many countries, the new year begins on the first day of January. Why? It is a civil calendar created for Western society beginning with the Roman calendar for the running of society. Astronomical calendars are based on major astronomical events such as solstices and equinoxes or risings of important stars and asterisms.

Astronomical New Year

In ancient societies in Europe and in Asia, indigenous people eagerly awaited the the return of the sun to their hemisphere after winter. They used an astronomical calendar. They carefully determined winter solstice day, the shortest day of the year and the day when the sun is lowest in the sky. They celebrated, for the sun is returning!

There are revival ceremonies in Japan to welcome back the sun. One of them is the Asadori Winter Solstice ritual that has continued for thousands of years in Central Japan.
