He married Toyatama-hime, the daughter of the sea-god, and they had a son, Ugaya-fuki-ayedsu no Mikoto, born, it is said, under an unfinished roof of cormorants' wings, who succeeded the father, and who married Tamayori-hime, also a daughter of the sea-god. This illustrious couple had four sons, of whom the last succeeded to the throne in the year B.C. 660. He was named Kamuyamatoi warehiko no Mikoto, but posterity has fortunately simplified his designation to the now familiar Jimmu-Tenno, the first historic Emperor of Japan, and the ancestor of the present emperor.
The histories of Japan, prepared under the sanction of the present Japanese government, date the commencement of the historic period from the first year of the reign of the first emperor, Jimmu-Tenno, who is said to have ruled for seventy-six years, viz., from B.C. 660 to 585. Some persons consider that this reign, and a few reigns that succeeded it, probably or possibly belong to the legendary period, because while, on the one hand, the Emperor Jimmu is described as the founder of the present empire and the ancestor of the present emperor, on the other, he is described as the fourth son of Ukay Fukiaezu no Mikoto, who was fifth in direct descent from the beautiful sun-goddess, Tensho-Daijin. But as no such thing as writing existed in Japan in those days, or for many centuries afterward, it would not be surprising if a real monarch should have a mythical origin assigned to him; and as I have quite lately heard the guns firing at Nagasaki an imperial salute in honor of his coronation, and have seen the flags waving over the capital city, Tokio, in honor of the birthday, the Emperor Jimmu is quite historical enough for my present purpose.
The commencement of his reign shall fix for us, as it does for others, the Japanese year 1, which was 660 years prior to our year 1, so that any date of the Christian era can be converted into one of the Japanese era by the addition of 660 years, and
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.
