It must be added that there was a bit of a sense of glorification, for this book was written in 1921, a time when loyal supporters of the Emperor at the end of the Edo Period were extolled owing to the historical view that Japan was peerless as a country under the eternal reign of a ceaseless line of "living-god" emperors.
もっとも同書は皇国史観に伴って幕末勤皇志士が持てはやされた大正10年（1921年）に記された本であり、いささか美化された感もあるとされる。
