The 6th century, in fact, represented a decline of Yamato power both at home and abroad. It was also marked by another shift of the court, this time back to the old region around Mount Miwa sometime late in the reign of Keitai (507–c. 531). From Keitai’s reign there was a marked reduction in royal power. A large force assembled to be sent against Silla, for example, had to be detoured to Kyushu in 527 to put down the rebellion of a local chieftain named Iwai, who had apparently refused to raise soldiers and supplies for the continental campaign. That campaign on the continent also ended in defeat, signaling the decline of Yamato power. The rest of the 6th century can be characterized by the growing accumulation of power by regional clan leaders and a weakening of royal power, as well as the rise of new clans, mostly of recent continental origin, who managed technical service groups.
Chief among them were the Soga, who under the successive chieftains Iname and his son Umako rose to positions of dominance at court. Possessed of administrative and technical skills, especially in the fiscal area, the Soga established marriage connections with the royal house that permitted them considerable influence at court. The Soga are also known as sponsors of Buddhism at the Yamato court. Ultimately, the Soga clan eclipsed all other clans at court, especially after the destruction of the Mononobe clan in a major battle in 587, and dominated the political scene. By the end of the 6th century, Japan had reached a low point in both foreign and domestic affairs.

During the declining years of the Yamato court, however, there was one event of the utmost cultural importance: the introduction of Buddhism from Paekche. The date of its introduction is traditionally set at either 538 or 552, but it seems likely that Buddhist beliefs had begun spreading among the Japanese at a much earlier date. Buddhism at first was an object of wonder and admiration, a rare item of foreign culture symbolized by its beautiful statuary, its imposing religious paraphernalia, and its majestic temples. The Buddhism that first spread among the Japanese was almost certainly a simple reliance on the magical aspects of the religion in seeking various benefits in the present world. It was regarded as especially important in protecting the state. A true understanding of its doctrines did not come until the time of Prince Shōtoku (Shōtoku Taishi).
The age of reform (552–710)
The idealized government of Prince Shōtoku
The Yamato court was resuscitated by efforts made within the royal family itself, efforts that in the course of a century reformed the government of the country and set it moving toward formation of a centralized state more suited to the new age. This era is sometimes called the Asuka period for the region south of modern Nara where the royal courts were located. The movement was touched off by the theories of ideal government expounded by Prince Shōtoku. Shōtoku served as regent for his aunt, the empress Suiko (ruled 592–628), who was enthroned after the murder of her predecessor, Sushun (it was during Suiko’s reign that the term tennō, or emperor, was adopted). Shōtoku took the Buddhist principles of peace and salvation for all beings as the ideal underlying his government. He made no move, even, to charge the murderer of Sushun but worked to convince him gradually, through the ideas of Buddhism, of the wrong he had done. The prince’s political policies, however, were based squarely on Chinese Confucian ideals.
The prince’s most striking domestic achievements were the establishment of a system of 12 court ranks in 603 and the Seventeen-Article Constitution in 604. The former, which made clear the relative stations of court officials by giving them caps of different colors, aimed to encourage the appointment of men of ability and give the court a proper organization and etiquette of its own. The ranks themselves were named for Confucian values—virtue, humanity, decorum, faith, righteousness, and knowledge, each in greater and lesser grades.
The constitution set forth the ideals of the state and rules for human conduct. It distinguished the ruler, government ministers, and the people as the three human elements making up the state and clearly laid down the duties and rights of each; it thus established the ideal of a centralized state presided over by a single ruler, and it provided a kind of basic law of the nation. The document not only shows the influence of Buddhism—of which the prince can be counted as the first major propagator in Japan—but also embodies many of the ethical and political doctrines of Confucian government, long since established in China and subsequently implemented in the kingdoms on the Korean peninsula as well. By borrowing the ideas and vocabulary of continental government, Shōtoku attempted to buttress the legitimacy of the royal house, which had suffered diminution at the hands of great clans.
Shōtoku’s chief achievement in foreign relations was the opening of relations with the Sui dynasty (581–618) of China. The exchanges between Japan and China in the 5th century had placed Japan in the position of a tributary state. Prince Shōtoku opened relations with Sui on an equal basis, supposedly shocking the Chinese emperor by addressing him as the ruler of the nation “where the sun sets,” while he was the ruler of the nation “where the sun rises.” Envoys were exchanged by the two countries. He also sent Japanese students to China to learn directly from Chinese culture, which had hitherto reached Japan via the states of Korea. Shōtoku was a profound student of Buddhism who gave lectures on the scriptures and himself wrote commentaries. His commentary on the Lotus Sutra, four volumes of which survive in the original draft written by the prince himself, may be called the oldest written work of known authorship in Japan.
As Buddhism gained ground, imposing temples were built in the Chinese style. The astonishment aroused by these great wooded buildings—often built with more than one story and with massive tiled roofs, where previously there had been only low, thatched houses—may well be imagined. A new civilization descended on Japan almost overnight. Of the temples built at the time, all that has survived of most of them are the foundation stones, but the Hōryū Temple, founded between 601 and 607 at Ikaruga in present Nara prefecture, still preserves its ancient wooden structures; its extant buildings, dating from the late 7th and early 8th centuries, are the oldest wooden structures in the world.
