Tokyo Imperial Palace is the main residence of the Emperor of Japan. It is a large park like area located in the Chiyoda area of Tokyo close to Tokyo Station and contains several buildings including the main palace, the private residences of the imperial family, an archive, museum and administrative offices.
It was built on top of what was called the Edo castle. The warrior Edo Shigetsugu built his residence here around the end of the Heian or the beginning of the Kamakura period. The Edo clan perished in the 15th century as a result of uprisings in the Kantō region, and Ōta Dōkan, a retainer of the Ogigayatsu Uesugi family, built Edo Castle in 1457 AD.
As can be seen in the above photo, the white upper part of this building rests on a polygonal wall of presumed hard and tight fitting stones. Did Japanese builders in the late 15th century have the capacity to do this masonry work?
And above we see stones of an even greater scale in another wall on the property. As you can see, some of the stones are as large as a person.
Here we see even more massive stones interlocking in this wall. Could it be, like in Cusco Peru we are looking at evidence of an earlier technological civilization whose works were later inherited by the Edo period Japanese?
Interestingly, above we see that excavations have shown the use of metal clasps, very similar to what have been found in enigmatic structures in Peru, Bolivia, Egypt and other locations.
Although not going to Japan anytime soon, we do offer tours of the megalithic works of Peru and Bolivia. Our last major tour is this September; registration and full payment are due by August 15, 2014:
