I just wanted to add the Fujiwara part of this nomination. 

I visited the site in 2010 where the Fujiwara Palace of the Asuka Period used to stand, as shown in the photo. 

I'd say this is important because the palaces of the kings, Tenno in Japanese, is perhaps the most important in any period.

In the Historic Monuments of Ancient Nara WHS, for example, the Nara Palace, called Heijo-kyo in Japanese, is the only one of its kind; all the other six elements of the WHS are religious edifices. (But the Nara Palace has been reconstructed; the Fujiwara Palace has not, as shown in the photo.)

In the Historic Monuments of Ancient Kyoto WHS I do not know why the Kyoto Palace, called Heian-kyo or Kyoto Gosho in Japanese, is not included in the WHS. It's most likely because it is just like the fact that the Jingu in Ise is not even nominated for a WHS, even though it is without a doubt the single most important historic site in Japan by any means: as the Japanese thinking goes, they are so important that they should not be protected by foreign money. 

The Fujiwara Palace can be most conveniently reached from the Yagi-Nishiguchi train station on the Kintetsu Kashihara Line, four stations north of the Asuka station.  From the train station it's about 2 km away.
