to be reduced, and not only was its chief, Ujimasa, a formidable foe, but also the topographical features of the district represented fortifications of immense strength. After various unsuccessful overtures, having for their purpose to induce Ujimasa to visit the capital and pay homage to the emperor, Hideyoshi marched from Kiōto in the spring of 1590 at the head of 170,000 men, his colleagues Nobuo and Iyeyasu having under their orders 80,000 more. The campaign ended as did all Hideyoshi’s enterprises, except that he treated his vanquished enemies with unusual severity. During the three months spent investing Odawara, the northern daimyōs surrendered, and thus the autumn of 1590 saw Hideyoshi master of Japan from end to end, and saw Tokugawa Iyeyasu established at Yedo as recognized ruler of the eight provinces of the Kwantō. These two facts should be bracketed together, because Japan’s emergence from the deep gloom of long-continued civil strife was due not more to the brilliant qualities of Hideyoshi and Iyeyasu individually than to the fortunate synchronism of their careers, so that the one was able to carry the other’s work to completion and permanence. The last eight years of Hideyoshi’s life—he died in 1598—were chiefly remarkable for his attempt to invade China through Korea, and for his attitude towards Christianity (see § VIII.: Foreign Intercourse).
The Tokugawa Era.—When Hideyoshi died he left a son, Hideyori, then only six years of age, and the problem of this child’s future had naturally caused supreme solicitude to the peasant statesman. He finally entrusted the care of the boy and the management of state affairs to five regents, five ministers, and three intermediary councillors. But he placed chief reliance upon Iyeyasu, whom he appointed president of the board of regents. Among the latter was one, Ishida Mitsunari, who to insatiable ambition added an extraordinary faculty for intrigue and great personal magnetism. These qualities he utilized with such success that the dissensions among the daimyōs, which had been temporarily composed by Hideyoshi, broke out again, and the year 1600 saw Japan divided into two camps, one composed of Tokugawa Iyeyasu and his allies, the other of Ishida Mitsunari and his partisans.
The situation of Iyeyasu was eminently perilous. From his position in the east of the country, he found himself menaced by two powerful enemies on the north and on the south, respectively, the former barely contained by a greatly weaker force of his friends, and the latter moving up Iyeyasu. in seemingly overwhelming strength from Kiōto. He decided to hurl himself upon the southern army without awaiting the result of the conflict in the north. The encounter took place at Sekigahara in the province of Mino on the 21st of October 1600. The army of Iyeyasu had to move to the attack in such a manner that its left flank and its left rear were threatened by divisions of the enemy posted on commanding eminences. But with the leaders of these divisions Iyeyasu had come to an understanding by which they could be trusted to abide so long as victory did not declare against him. Such incidents were naturally common in an era when every man fought for his own hand. The southerners suffered a crushing defeat. The survivors fled pell-mell to Osaka, where in a colossal fortress, built by Hideyoshi, his son, Hideyori, and the latter’s mother, Yodo, were sheltered behind ramparts held by 80,000 men. Hideyori’s cause had been openly put forward by Ishida Mitsunari and his partisans, but Iyeyasu made no immediate attempt to visit the sin upon the head of his deceased benefactor’s child. On the contrary, he sent word to the lady Yodo and her little boy that he absolved them of all complicity. The battle of Sekigahara is commonly spoken of as having terminated the civil war which had devastated Japan, with brief intervals, from the latter half of the 12th century to the beginning of the 17th. That is incorrect in view of the fact that Sekigahara was followed by other fighting, especially by the terrible conflict at Osaka in 1615 when Yodo and her son perished. But Sekigahara’s importance cannot be over-rated. For had Iyeyasu been finally crushed there, the wave of internecine strife must have rolled again over the empire until providence provided another Hideyoshi and another Iyeyasu to stem it. Sekigahara, therefore, may be truly described as a turning-point in Japan’s career and as one of the decisive battles of the world. As for the fact that the Tokugawa leader did not at once proceed to extremities in the case of the boy Hideyori, though the events of the Sekigahara campaign had made it quite plain that such a course would ultimately be inevitable, we have to remember that only two years had elapsed since Hideyoshi was laid in his grave. His memory was still green and the glory of his achievements still enveloped his family. Iyeyasu foresaw that to carry the tragedy to its bitter end at once must have forced into Hideyori’s camp many puissant daimyōs whose sense of allegiance would grow less cogent with the lapse of time. When he did lay siege to the Osaka castle in 1615, the power of the Tokugawa was well-nigh shattered against its ramparts; had not the onset been aided by treachery, the stronghold would probably have proved impregnable.
But signal as were the triumphs of the Tokugawa chieftain in the field, what distinguishes him from all his predecessors is the ability he displayed in consolidating his conquests. The immense estates that fell into his hands he parcelled out in such a manner that all important strategical positions were held by daimyōs whose fidelity could be confidently trusted, and every feudatory of doubtful loyalty found his fief within touch of a Tokugawa partisan. This arrangement, supplemented by a system which required all the great daimyōs to have mansions in the shōgun’s capital. Yedo, to keep their families there always and to reside there themselves in alternate years, proved so potent a check to disaffection that from 1615, when the castle of Osaka fell, until 1864, when the Chōshū rōnin attacked Kiōto, Japan remained entirely free from civil war.
It is possible to form a clear idea of the ethical and administrative principles by which Iyeyasu and the early Tokugawa chiefs were guided in elaborating the system which gave to Japan an unprecedented era of peace and prosperity. Evidence is furnished not only by the system itself but also by the contents of a document generally called the Testament of Iyeyasu, though probably it was not fully compiled until the time of his grandson, Iyemitsu (1623–1650). The great Tokugawa chief, though he munificently patronized Buddhism and though he carried constantly in his bosom a miniature Buddhist image to which he ascribed all his success in the field and his safety in battle, took his ethical code from Confucius. He held that the basis of all legislation and administration should be the five relations of sovereign and subject, parent and child, husband and wife, brother and sister, friend and friend. The family was, in his eyes, the essential foundation of society, to be maintained at all sacrifices. Beyond these broad outlines of moral duty it was not deemed necessary to instruct the people. Therefore out of the hundred chapters forming the Testament only 22 contain what can be called legal enactments, while 55 relate to administration and politics; 16 set forth moral maxims and reflections, and the remainder record illustrative episodes in the career of the author. No distinct line is drawn between law and morals, between the duty of a citizen and the virtues of a member of a family. Substantive law is entirely wanting, just as it was wanting in the so-called constitution of Prince Shōtoku. Custom, as sanctioned by public observance, must be complied with in the civil affairs of life. What required minute exposition was criminal law, the relations of social classes, etiquette, rank, precedence, administration and government.
Society under feudalism had been moulded into three sharply defined groups, namely, first, the Throne and the court nobles (kuge); secondly, the military class (buke or samurai); and thirdly, the common people (heimin). These lines of cleavage were emphasized as much as possible Social distinctions in the Tokugawa Era. by the Tokugawa rulers. The divine origin of the mikado was held to separate him from contact with mundane affairs, and he was therefore strictly secluded in the palace at Kiōto, his main function being to mediate between his heavenly ancestors and his subjects, entrusting to the shōgun and the samurai the duty of transacting all worldly business on behalf
