After the death of the Emperor Jimmu there appears to have been an interregnum for three years—although it is seldom taken account of—the second Emperor Suisei, who was the fifth son of the first emperor, having ascended the throne B.C. 581 and reigned till 549. The cause of the interregnum appears to have been the extreme grief which Suisei felt at the death of his father, in consequence of which he committed the administration of the empire, for a time, to one of his relatives—an unworthy fellow, as he proved, named Tagishi Mimi no Mikoto, who tried to assassinate his master and seize the throne for himself, and who was put to death by Suisei for his pains. The fifth son of the Emperor Jimmu was nominated by him as the successor, and it is probable that older sons were living and passed over, and that the throne was inherited in part by nomination even in this its first transfer.
Some writers on Japanese history profess to see in the pantheon of Japan, pictured in the Kojiki and Nihonki, nothing more than a collection of distinguished personages who lived and labored and contended in the country before the historic period, thus bringing deified men and women down to earth again. Such persons accept the records of Jimmu-Tenno’s origin as essentially accurate in so far as they state what is human and reasonable, rejecting them only when they set forth what is supernatural, and, to them, unbelievable.
Others, on the contrary, consider, or profess to consider, the supernatural portions of those narratives as perfectly trustworthy, and discredit only those statements concerning the first of the sacred emperors which would seem in any way to detract from his divinity. I should be sorry to have to argue the case with either of these parties, but I must take the liberty of accepting as sufficiently accurate as much of the recorded lives of Jimmu and his successors as the modern prosaic histories in Japan are content to put forth, and no more.
Proceeding upon this basis, there is not much to be said of the reigns of the mikados who ruled before the Christian era, beyond what has been already stated. As regards the first emperor, his ancestor Ninigi no Mikoto—whether a god or not, or whether he came down from the sun by means of “the bridge of heaven” or not—appears to have established his residence at the ancient Himuka, now Hiuga; there it was that Jimmu-Tenno first resided, and thence it was that he started on his historic and memorable career. The central parts of Japan were militarily occupied by rebels (whose names are preserved), and it was to subdue them that he proceeded eastward. He stopped for three years at Taka Shima, constructing the necessary vessels for crossing the waters, and then, in the course of years, making his way victoriously as far as Nanieva, the modern Osaka, encountered his foes at Kawachi, and defeated them, the chief general being left dead on the battle-field.
