Two developments led to the establishment of these sanctuaries as Shinto shrines. First, the introduction of Buddhism from China via Korea in the sixth century led the Emperor to welcome Buddha as a great kami whose visible representation was housed
in an impressive Buddhist temple. This had a profound influence on the development of Shinto shrines and on the emergence of permanent shrine sanctuaries in particular. Second, the gradual deification of the Emperor led to the establishment of an offic
ial Shinto shrine. Yamato rulers unified several competing clan lineages in the Yamato Plain in central Japan at least as early as the late third and forth centuries A.D. under the aegis of their lineage, the Sun Line. The Emperor became regarded as a
living kami, and his divinity surpassed that of other kami. His new status fostered the idea of the Shinto shrine. Therefore, political authority, whether gained by force or long practiced political prestige, was sanctioned by religious belief sanctified
at the Inner Shrine at Ise. The sacred necklace of magatama (jewels representing the soul spirit which enter the body of the possessor) is the symbol of succession from the Sun Goddess to the Sun Line and is the emblem of the enthronement of the emperor
s of Japan until today. The necklace is kept at Ise. It was at Ise that Shinto doctrines were first systematically expounded. The site is still venerated, and pilgrimages are carried out today in an expression of patriotic semtiment.
