In the history of China a belief is recorded that the Japanese sovereigns are descended from a Chinese prince, Tai Peh, whose father wished to disinherit him in favour of a younger son. Tai Peh fled to Wu in the present Chekiang, and thence passed to Japan about 800 B.C. Another record alleges that the first sovereign of Japan was a son of Shao-kang of the Hsia dynasty (about 850 B.C.), who tattooed his body and cut off his hair for purposes of disguise and lived on the bank of the Yangtsze, occupying himself with fishing until at length he fled to Japan.
That Ninigi may have been identical with one of these persons is not inconceivable, but such a hypothesis refuses to be reconciled with the story of the fighting in Izumo which preceded the descent to Tsukushi. The much more credible supposition is that the Yamato Court, confronted by a formidable rebellion having its centre in Izumo, retired to Tsukushi, and there, in the course of years, mustered all its followers for an expedition ultimately led by the grandson of the fugitive monarch to restore the sway of his house. This interpretation of the legend consists with the fact that when Jimmu reached Yamato, the original identity of his own race with that of the then ruler of the province was proved by a comparison of weapons.
THE CASTLE OF THE OCEAN KAMI
With regard to the legend of the ocean Kami, the rationalists conceive that the tribe inhabiting Tsukushi at the time of Ninigi's arrival there had originally immigrated from the south and had gradually spread inland. Those inhabiting the littoral districts were ultimately placed by Ninigi under the rule of Prince Hohodemi, and those inhabiting the mountain regions under the sway of Prince Hosuseri. The boats and hooks of the legend are symbolical of military and naval power respectively. The brothers having quarrelled about the limits of their jurisdictions, Hohodemi was worsted, and by the advice of a local elder he went to Korea to seek assistance. There he married the daughter of the Ocean King—so called because Korea lay beyond the sea from Japan—and, after some years' residence, was given a force of war-vessels (described in the legend as "crocodiles") together with minute instructions (the tide-ebbing and the tide-flowing jewels) as to their skilful management. These ships ultimately enabled him to gain a complete victory over his elder brother.
WHAT THE JAPANESE BELIEVE
These rationalizing processes will commend themselves in different degrees to different minds. One learned author has compared such analyses to estimating the historical residuum of the Cinderella legend by subtracting the pumpkin coach and the godmother. But we are constrained to acknowledge some background of truth in the annals of old Japan, and anything that tends to disclose that background is welcome. It has to be noted, however, that though many learned Japanese commentators have sought to rationalize the events described in the Records and the Chronicles, the great bulk of the nation believes in the literal accuracy of these works as profoundly as the great bulk of Anglo-Saxon people believes in the Bible, its cosmogony, and its miracles.
The gist of the Japanese creed, as based on their ancient annals, may be briefly summarized. They hold that when the Sun goddess handed the three sacred objects to Ninigi—generally called Tenson, or "heavenly grandchild"—she ordained that the Imperial Throne should be coeval with heaven and earth. They hold that the instructions given with regard to these sacred objects comprised the whole code of administrative ethics. The mirror neither hides nor perverts; it reflects evil qualities as faithfully as good; it is the emblem of honesty and purity. The jewel illustrates the graces of gentleness, softness, amiability, and obedience, and is therefore emblematic of benevolence and virtue.* The sword indicates the virtues of strength, sharpness, and practical decision, and is thus associated with intelligence and knowledge. So long as all these qualities are exercised in the discharge of administrative functions, there can be no misrule.
*It must be remembered that the jewel referred to was a piece of green or white jade.
They further hold that when the Sun goddess detailed five Kami to form the suite of Ninigi, these Kami were entrusted with the ministerial duties originally discharged by them, and becoming the heads of five administrative departments, transmitted their offices to generation after generation of their descendants. Thus Koyane was the ancestor of the Nakatomi family who discharged the priestly duties of worship at the Court and recited the Purification Rituals; Futodama became the ancestor of the Imibe (or Imbe), a hereditary corporation whose members performed all offices connected with mourning and funerals; Usume became ancestress of the Sarume, whose duties were to perform dances in honour of the deities and to act as mediums of divine inspiration; Oshihi was the ancestor of the Otomo chief who led the Imperial troops, and Kume became the ancestor of the Kumebe, a hereditary corporation of palace guards. Further, they hold that whereas Ninigi and his five adjunct Kami all traced their lineage to the two producing Kami of the primal trinity, the special title of sovereignty conferred originally on the Sun goddess was transmitted by her to the Tenson (heavenly grandchild), Ninigi, the distinction of ruler and ruled being thus clearly defined. Finally they hold that Ninigi and these five adjunct Kami, though occupying different places in the national polity, had a common ancestor whom they jointly worshipped, thus forming an eternal union.
