The Emperor Jimmu after his accession continued to reign seventy-five years and, according to the _Kojiki_, died at the age of one hundred and thirty-seven. The _Nihongi_, however, gives his age at death as one hundred and twenty-seven, and this has been adopted by the government in its published chronology.(52) His burial place is said to be on the northern side of mount Unebi in the province of Yamato. It is just to assign to the Emperor Jimmu the exalted place which the Japanese claim for him in their history. That he was a prince of high enterprise is evident from his adventurous expedition from the home of his family into the barbarous and unknown regions of the Main island. He accomplished its conquest with less slaughter and cruelty than the customs of the times seemed to justify. He made it his policy to effect terms with the native princes and seek their co-operation in his government. He extended his sway so that it covered Anato, now known as Nagato, and Izumo on the west, and reached probably to Owari on the east. All this time he had held a firm hand on the island from which he had come, so that few if any outbreaks occurred among its restless Turanian or native inhabitants. The Emperor Jimmu was succeeded by his third son, known by his canonical name as the Emperor Suizei. The reigning emperor, it seems, exercised the right to select the son who should succeed him. This was not always the oldest son, but from the time he was chosen he was known as _taishi_, which is nearly equivalent to the English term crown prince. The Emperor Suizei, it is said, occupied a palace at Takaoka, in Kazuraki, in the province of Yamato. This palace was not far from that occupied by his father, yet it was not the same. And in the reigns of the successive sovereigns down to A.D. 709, when the capital was for a time established at Nara, we observe it as a most singular circumstance that each new emperor resided in a new palace. In the first place, the palace spoken of in these early times was probably a very simple structure. Mr. Satow, in his paper(53) on the temples at Isé, gives an account of the form and construction of the prehistoric Japanese house. The Shintō temple in its pure form is probably a survival of the original palace. Before the introduction of edge-tools of iron and boring implements or nails, the building must have been constructed in a very primitive fashion. It will be understood that stone or brick were never used. Wood was the only material for the frame. The roof was thatched with rushes or rice straw. The pure Shintō temples of modern times are built with the utmost simplicity and plainness. Although the occasion for adhering to primitive methods has long since passed away, yet the buildings are conformed to the styles of structure necessary before the introduction of modern tools and appliances. To build a new palace therefore for a new emperor involved by no means such an outlay of time and work as might be imagined.
