According to tradition, Itsuse and Iwarehiko took counsel together one day in their residence in Hyūga, as to the place most suitable for the seat of administration, and resolved to proceed eastward. At the straits between Kiushū and Shikoku they were received by a terrestrial deity, and under his guidance reached Usa in the present Buzen, where the inhabitants built a palace for them and treated them hospitably. Passing next to Chikuzen, they subsequently crossed the sea to Aki on the main island, and thence journeyed to Kibi, ten years being devoted to these travels. From Kibi they passed over by Naniwa to Tadetsu in the present Izumi province. The objective point of the expedition was Yamato, where then ruled a powerful chieftain named Nagasunehiko who, under the authority of Nigihayahi, a scion of a god of Heaven, whom he had received, had extended his sway over the surrounding region. This chieftain, learning of the approach of the deities and their following, marshaled his forces to oppose them. In the battle that ensued Itsuse was wounded by an arrow. The invading army therefore turned their course over the sea to Kii, where Itsuse died of his wound. His brother, Iwarehiko, then advanced to the east coast of Kii, and, having there killed a local chieftain, pushed on to Yoshino under the guidance of Prince Michiomi (ancestor of the Ōtomo family) and Prince Ōkume (ancestor of the Kume family). The inhabitants, cave-dwellers, learning that a scion of the god of Heaven had arrived, went out to meet him and made submission. Prosecuting his campaign, Iwarehiko struck down several rebel chiefs, and once more planned an expedition against Nagasunehiko. The latter, however, sent him a message, saying: "Prince Nigihayahi, son of the Deity of Heaven, came hither in a strong boat, and married my sister, Kashiya, by whom he has a son, Prince Umashimate. I have made obeisance to Prince Nigihayahi as sovereign of the land. There cannot possibly be two legitimate representatives of the Heavenly Deity. You must have come to deprive us wrongfully of the realm under pretext of celestial origin." To this Iwarehiko replied: "There is more than one son of the Deity of Heaven. If your sovereign be in truth the offspring of the Celestial Deity, he must possess some proofs. Let me see them." Nagasunehiko thereupon produced arrows and an arrow-case which Prince Nigihayahi had brought with him. Iwarehiko, having examined them, declared them to be genuine, and showed his own arrows and arrow-case to Nagasunehiko. But the latter, though fully sensible that Iwarehiko was of celestial origin, maintained an obstinate mien and would not change his view. Prince Nigihayahi, now clearly perceiving his unreasonable disposition, put him to death, and passed over with all his men to serve in the invading army. Well pleased by this act, Iwarehiko treated the prince kindly and rewarded his loyal conduct. Orders were then issued to the
