Land of the Rising Sun

From the introduction:

Far to the east, there lies a land of demons and steel. An archipelago, a seemingly small set of islands compared to it’s neighbors, yet the focus of so much of this world’s destiny can be found here. The history to be discovered ranges from the earliest moments of the Common Era to a mere few years before our modern day. This is Japan, the Land of the Rising Sun, as it appears in the Nasuverse.
