This philological study of ancient Japan owed much, in its early stage, to the stimulus given by the growth of historiography in the seventeenth century. This study of and the endeavour to write down the national history came of course from the political necessity of the time. As early as the fourth decade of the seventeenth century, the Shogunate is said to have ordered its court literati to compile the history of our country from the earliest times, but it was suspended afterwards for a while. A little posterior to this, a memorable historiographical institute was initiated by Mitsukuni Tokugawa, one of the grandsons of Iyeyasu and lord of Mito. For the first time in our country, the collection of historical materials was undertaken on a grand scale. Collectors were despatched to many provinces where a rich harvest was expected. Kyoto and its vicinity were ransacked with special attention. The material thus rummaged and collected, varying from those of authentic kinds such as memoirs of ancient courtiers and court-ladies, chronicles kept in shrines and temples, and documents concerning the transactions of numberless manorial estates, down to less reliable sorts of materials such as stories, legends, tales, novels, and various other writings current in successive ages, had been criticised in their texts with tolerable scientific conscientiousness. The Dai-Nihon-shi, or "The History of Great Japan," which is the result of the coöperation of the historians of the Mito school engaged in researches under the auspices of Mitsukuni and his successors, consists of two hundred and thirty one volumes, and has taken two centuries and a half for its completion, the last volume having been published in 1906. In its form the grand history is an imitation of the Shih-chi by Ssuma-chien of the Han dynasty, the whole system being divided into the three sections of the annals of the emperors, biographers of noted personages, and miscellanies, with various tables. It is by no means a complete history of Japan, for it comes down only to 1392, the year in which the two rival houses of the Imperial family were united and put an end to the long civil war. Moreover, it was only in the middle of the nineteenth century, that the first two sections were put into print, though as manuscripts those parts had been finished much earlier. It is not, therefore, on account of the publication of the history, but of the researches themselves and their by-products, that the historiography of the Mito school greatly influenced the rise of the nationalistic spirit of the Japanese. The long arduous labours of these historians were consummated in expounding the doctrine that the Japanese nation had something unique in its civilisation which was worthy to be guarded carefully and fostered, and that the only bond which could unite the nation spiritually was fidelity towards its common centre, the Emperor, whose family had continued to reign over the country since time immemorial. The history is often criticised as being too pragmatic, narrow, and subjective, therefore not scientific. If we consider, however, that even in those countries in the West where the study of history is boasted of as having reached a high stage of scientific investigation, most of the historians, if not the histories they have written, have been also decidedly pragmatic, so that few of them can be called perfectly objective, then we should not much blame the historians and the history of the Mito school. That the school was entirely free from any sort of superstition must also be mentioned as one of its chief merits. This may be attributed to the rationalistic influence of the doctrine of Chutse, and the fact that the history was written in orthodox Chinese shows how these historiographers were imbued with Chinese ideas. It might be said, however, to their credit that the task was first undertaken in an age in which the literary language of our country had not yet become entirely independent of Chinese, and that, notwithstanding the adoption of that language, in committing the result of their researches to writing they had never fallen into the self-deception which might come from sinicomania. Since the inception of this ever-memorable historiographical undertaking, the town of Mito had continued to be the hearth of nationalism and patriotism, and thinkers devoted to these ideas had been very glad to make their pilgrimage from all parts of Japan to the centre of the pure Japanese culture, and to converse with these historians of the noted institution. It was indeed the early groups of these historians who first stirred up the nationalistic spirit in the later seventeenth century, and their successors it was who accelerated and most strongly reinforced the national movement just before the Revolution. No school of learning in Japan had even been so powerful and effective as that of Mito in influencing and leading the spirit of the nation.
The torch, however, which had succeeded in giving blissful light to illumine the whole nation, burned at last the torch-bearer himself with its blazing flame. Not to mention that the finances of the territorial lord had been miserably drained by this undertaking, which is said to have swallowed up about one-third of the whole revenue of the territory, and therefore proved too heavy a burden for the small income of the lord. Narrow-mindedness, which is the necessary consequence of rigorism, tended to nurture an implacable party spirit among the samurai of the territory educated in this principle. Internal strife thus ensued which implicated not only the whole samurai but people of all classes. In short, the territory was divided against itself. Both parties appealed to arms at last, and fought against each other, until both had to lie down quite exhausted. So the culture which the historians and the samurai of Mito raised to a high pitch proved to be disastrous to their own welfare, yet the good which it did to the country at large should remain as a glory to those who sacrificed themselves for what they regarded as their ideal.
We see now that several forces had coöperated in accomplishing the final unity and consolidation of the nation. In giving the finishing touch, however, to the task of many centuries, the enigmatic relations between the Emperor and the Shogun had necessarily to be cleared. Though the Shogunate had continued to transact the state affairs as if he had been the sole regent of the Emperor, the legal status of the former had never been created by any ordinance issued by the latter. No emperor had ever formally confided his political prerogative to the Shogun. The basis on which the jurisdictional power of the Shogun had rested was nothing but the fait accompli connived at and acquiesced in by the Emperor. If the prestige of the Emperor, therefore, which had once fallen into decadence, should be revived, the position of the Shogun was sure to become untenable. The historians of the Mito school tried their best to make the Emperor the nucleus of the national consolidation. Their political theory had been strongly influenced by the legitimism entertained by the historians of the Sung dynasty, and this principle of legitimacy, when applied to the history of Japan, must have led only to the conclusion that the only legitimate and therefore actual sovereign of the country could be none other than the Emperor himself. Needless to say, such an argument was injurious to the political interests of the Shogunate, so that it seems very strange that the theory had been upheld and loudly heralded by these historians who were under the protection of the lord of Mito, the descendant of a scion of Iyeyasu. It was not, of course, the intention of the hereditary lords of Mito and their historians to undermine the structure of the Shogunate from its foundation. Having been, however, too sharp and fervent in their argument, they had been unable to rein themselves in, before the interests of the Shogunate were thereby jeopardised, and as a logical consequence they brought unconsciously to a terrible catastrophe the whole edifice of the military régime, in which alone they could find a reason for their existence.
The spirit of the nation had thus been under the increasing notion that the coexistence of the sovereign Emperor with the omnipotent Shogunate would be ultimately impossible, and such a trend of thought had been highly welcomed in those parts of Japan where militarism had the least hold. So far, however, it had been the more logical pursuance of a political ideal, and if no opportunity had presented itself to these idealists to put their theory into execution, it would have remained for long the idle vapouring of romantic and irresponsible politicians. That Japan was saved from this inaction, and that the virile movement in favour of the revival of the imperial prestige was at last undertaken, must be attributed to the shock and stimulus which came from without, that is to say, to the coercion on the part of the Western nations to open to them our country, which had been so long secluded from the rest of the world.
Since the so-called "closing of the country" the Japanese had enjoyed a peaceful national life, undisturbed for more than one century and a half, and during this period of long tranquillity Japan had been able to prepare herself for the hardships which she was about to encounter, by replenishing her national culture and transforming it so as to be able to take in as much of the Western civilisation as she was in need of, without fear of thereby endangering her own national existence. But at the end of the eighteenth century the insistent knocking of foreigners at the door began to be heard, first at the back-door of the Island Empire. It was only the Russians who, having already annexed the vast tract of Siberia, were now ready to make a jump forward, and loitered on the northern coast of our Hokkaidô, called the island of Yezo at that time. This was the beginning of new national troubles. It was not, however, the same kind of foreign troubles as those which we had tried and succeeded in getting rid of in the early days of the Shogunate. There was no fear now of suffering from the religious intrigues of foreign missionaries. The danger, if there were any, was purely of a political nature.
Needless to say, the nation had had no voice in determining the Shogunate's policy of "shutting up the country", and had not understood well the merit or demerit of the policy itself, but having been accustomed for a long time to the isolated national existence, and puffed up not a little into self-conceit by the growth of the nationalistic spirit, they were unconsciously induced to believe that the status they were in must be the only normal condition of the country. The people at large, though relieved of the overdue influence of China, yet had a very scanty knowledge of the condition in which Europe and America were at that time, and did not wish, in the least, to be deranged by the intrusion, however well-meant, of any foreigner into their quiet abode, in spite of the utter impossibility of continuing such a national life ad infinitum in the face of the changed circumstances of the world, caused by the eastward expansion of various European nations, and by the rise of a new power on the American continent, the power which had just acquired access to the shore of the Pacific. Those who were then at the helm of state, that is to say, the statesmen of the Shogunate, shared nearly the same opinion with the nation at large. Not only for the national welfare, but in the interests of the Shogunate itself, they thought it best to keep up the status quo as long as possible. Unfortunately, the foreigners who now knocked at our doors were not unarmed like those who had come two centuries before, neither were they so humble and docile as the Dutchmen at Deshima were accustomed to be. In order to keep them off in spite of their importunate wish to the contrary, we had to provide for emergencies. So the Shogunate tried to make military preparations, to defend the country in case of necessity and drive away the intruders by force of arms. The more, however, the Shogunate tried to arm the nation against the foreigners, the more difficult it found the task it had in view. As the result of the long enjoyment of peace, the people had become inured to ease and luxury, and had lost much of their martial spirit, of which they had been exceedingly proud as their characteristic attribute. Moreover, the country having been parcelled out into nearly three hundred territories, it was very hard for the Shogunate to mobilise the warriors of the whole empire at its sole command. On the other hand, the material progress of the Western nations, achieved during the time of our seclusion, had been really astonishing. The difficulty of coping with them now became far greater for us than it had been at the end of the sixteenth century. Notwithstanding these overwhelming difficulties, the Shogunate persisted in its endeavour to strengthen the national defences. The martial spirit of the nation was gradually reawakened, but new internal difficulties were created by thus mobilising the nation, divided as it was into motley groups. The martial spirit which the Shogunate aroused was turned against itself, and the Shogunate proved unable to steer through the crisis at last.
At first the opinion of the educated class of the nation was conflicting, but a few were eager to see the necessary overthrow of the régime of the Shogun. The great part gradually concurred in denouncing the incapacity of the Shogunate to fulfil by itself the task which it was called upon to accomplish. Still many were in favour of supporting the Shogunate in order to enable it to carry through its traditional policy of seclusion. Some advocated even the closer union of the Shogunate with the Imperial court, which was now beginning to become again the influential political centre of the nation in opposition to the power at Yedo, so that there might have been a fear of the two powers coming into collision. The conclusion, however, of the treaty with the United States in 1858, and subsequently with other powers, bitterly disappointed these sincere friends of the Shogunate and emboldened its adversaries. Hitherto those who had diametrically opposed the Shogunate were men who had never been in any position politically responsible. In other words, they were doctrinaires, and not men of action, so that there could be no serious danger to the Shogunate so long as they contented themselves only with arguing about national affairs in highflown language. But the disappointment which the Shogunate gave to its friends, turned them into sympathisers with the radical opponents. The danger was thus shifted from foreign relations to the serious internal question, whether the Shogunate should be allowed to exist any longer or not. Those who wished for the revival of the imperial prestige or the overthrow of the existing régime, whatever form the revolution might take, wielded as their forcible weapon to attack the Shogunate the denunciation that the sacred Land of the Gods had been opened to the sacrilegious tread of hairy barbarians, and their slogan was so persuasive that it led the imperial court at Kyoto to issue an order urging the Shogunate to repudiate the already concluded treaties and to return to the time-honoured seclusion policy, a task of utter impossibility. To this august command from Kyoto, the Shogunate could but respond very obsequiously, being intimidated somewhat by the loud clamour of these conservative patriots. Or it may be said that the military government succumbed to the combined force of the court-nobles and the territorial politicians. The marriage of the fourteenth Shogun to one of the sisters of the Emperor Kômei, in the year 1861, though concluded for the sake of the rapprochement of the Imperial court and the Shogunate, did not prove so serviceable in saving the tottering edifice of the Tokugawa régime as had been expected. Finding that the power and the resources of the Shogunate were inadequate to perform the duty which it had pledged itself to accomplish, Yoshihisa Tokugawa, the fifteenth and last of the Shogun, resigned all the power he had, political as well as military, into the hands of the Emperor Meidji, who had just succeeded his father the Emperor Kômei. This happened in November of the year 1867. A little previous to this the proposition of the Shogunate to open the port of Hyogo, now Kobe, to foreign trade was agreed to by the Emperor, a fact which proves how difficult it was to maintain the out-of-date seclusion-policy. From this it can be seen that the Shogunate of the Tokugawa fell, after the lapse of two hundred sixty four years from its beginning, not from lack of foresight on the part of their statesmen, but solely from loss of prestige.
The prestige of the Shogunate was lost, simply because the system, such as it was, had become anachronistic in the face of the altered conditions of the country, which had been steadily progressing during these centuries. In other words, the Tokugawa Shogunate had been undermining itself for a long time by having courageously undertaken the honourable task which it was destined to perform in our national history, and it collapsed just in time when it had accomplished its mission. The fall of the Shogunate, therefore, must be said to have taken place very opportunely. The overthrow of the Shogunate, however, did not mean the mere downfall of the House of the Tokugawa; but it was the final collapse of the military régime, which had actually ruled Japan for nearly seven centuries, and the demolition of such a grand and elaborate historical edifice as the Shogunate could not be expected to be carried out without a catastrophe. That catastrophe came in the form of a civil war, which raged over the country for more than a year.
After the resignation of the last of the Shogun, the new government was instantly set up at Kyoto, at the head of which an imperial prince was placed, who had to control all the state business in the name of the Emperor. The councillors under him were chosen not only from court-nobles, but also from the able samurai who belonged to the party antagonistic to the Shogunate. This exasperated the partisans of the last Shogunate. Though the ex-Shogun had renounced his hereditary rights as the actual ruler of Japan, he still remained a daimyo even after his resignation, and as a daimyo he was the most powerful of all, for he had a far greater number of the samurai under him in his hatamoto than any other of his colleagues. Besides, he had many sympathisers among the daimyo. These vassals and friends of the ex-Shogun were discontented at the turn which the course of events had taken, and wished at least to rescue him from a further decrease of his influence. Induced at last by these followers to try his fortune, the ex-Shogun asked for an imperial audience, which was refused. Then he attempted to force his entrance into the city of Kyoto, escorted by his own guards and the forces of the friendly daimyo, and was met by the Imperialist army, composed of the forces of the lords of Satsuma, Nagato, Tosa, Hizen, and other daimyo, the greater part of whom had their territories in the western provinces of Japan. At the end of January, 1868, the two opposing armies came into collision at Fushimi and Toba, villages in the southern suburb of the old metropolis, and the forces of the ex-Shogun gave way. Yoshihisa hurriedly retreated to Ôsaka with his staff, and thence by sea to Yedo, whither the imperial army pursued him by the land-route.
At Yedo some of the vassals of the Tokugawa could not make up their minds to submit complacently to the unavoidable lot of their suzerain and of themselves, and insisted on making their last stand against the approaching Imperialists by defending the city. But the wiser counsel prevailed, and the castle was surrendered to the Imperialists without bloodshed at the end of April. A handful of desperate samurai, who fortified themselves in the precincts of the Temple of Uyeno, the site of the present metropolitan park, was easily subdued by the Imperialists. The ex-Shogun, who had been interned at Mito on account of his having fought against the Imperialists, was released soon afterwards. By an Imperial grace, a member of a lateral branch of the Tokugawa was ordered to succeed the ex-Shogun as daimyo, and made the hereditary lord of Suruga. The first phase of the Revolution thus came to an end.
