Japan is a country inhabited by a people differing remarkably in racial features from those who now occupy the greater part of Europe. She remained for a long time shut up against the foreigners knocking at her gate, and on that account her history, compared with that of other nations, presents striking and unique characteristics. Many ancient manners and customs, some of them having their origins in ages prehistoric and unintelligible even to the present Japanese themselves, are handed down almost unchanged to this day. On the other hand, the history of Japan is not so simple as the histories of many semi-civilised countries, which are generally nothing but incredible legends and records of chronic disturbances arising out of some inevitable natural causes. Full of charming oddities, which might provide sources of wild speculations, and at the same time not lacking a certain complexity,--a complexity indispensable if it is to become an object of interest and investigation to any scientific historian, the history of Japan should prove a very fascinating study. In this it resembles the relation many rare indigenous flora and fauna bear to foreign biologists. It should be noticed, however, that biologists may safely remain constant as regards their points of view, whatever plant or animal they happen to study, while historians ought always to bear in mind that every nation and every age has its own criterion. In the study of Japanese history the same truth must hold good. It is a very regrettable fact, however, that many foreign Japanologists are too fond of neglecting the Japanese point of view, and would like to apply the western standard to the things Japanese they encounter in their researches concerning our country. Frequently they are rash enough to criticise before they have a proper understanding of those things which it is their business to criticise. Sometimes they get at a truth to which Japanese scholars have never attained, but they almost as a rule forget that things Japanese too should be considered from many sides, as occidental things should necessarily be, and inflexibly adhere to that one line of insight which they were once fortunate enough to seize. Or sometimes they attack pitilessly those legendary parts of our history, which are to be found in some school text-books or are not yet entirely expunged from some more scholarly works, on account of a national reluctance to part with those cherished memories of our forefathers. They blame us as if no country in the world were chauvinistic except Japan, and Japan only. Such treatment of Japanese history, however, will avail them nothing at all, not to mention that we suffer very much in our outward relations from it. As chapter II. and the following, however, are chiefly devoted to the purpose of showing that the history of Japan may be interpreted side by side with that of many European nations, I will cease dwelling further on this topic, and will directly
