Unfortunately, during the battle with the army of Nagasune-hiko, Ituse-no-mikoto, who was elder brother of the Sumera-mikoto, happened to injure his elbow by a stray arrow. Because of his wound, the royal army could not help ceasing from the battle unavoidably.
When the troops of the Sumera-mikoto appeared on the mountain side of Ikoma, Nagasune-hiko, who was the chief of the opposite force, was informed that they were in a critical situation. Hearing this report, Nagasune-hiko was assured that the reason why the descendant of the deities from the Heaven came up to his area must have been in order to usurp his nation. Thus, both of whole armies began a combat and fought fiercely at Kusae-no-saka.
On 9th of April of this summer, the royal army managed to prepare for armaments and marched towards Tatuta. Because the road leading to Tatuta was too steep to line up two files, they decided to turn back halfway and advance into inside of the opposite nation over the Mt. Ikoma.
On 11th of February in 659 B.C., the party of the Sumera-mikoto with building the royal navy launched towards the East along the Setouti Sea. Fastening bows of ships with ropes together and just arriving at the port Naniha, the tide helped them to sail faster. The place where the party of Sumera-mikoto landed was named Namihaya-no-kuni, which signifies fast tide in Japanese, after this legend.
The Chronicle of Japan was formally edited in 720 A.D. by Prince Toneri, who was one of grandsons of Temmu-Tennow. However, it has been inferred that Prince Toneri would have consulted to ancient documents and manuscripts which maybe had been handed down from generation to generation within the Tennow family and those of mighty tribes. If the term Atai was used from the 5th to 6th century as we mentioned above, one of the old documents should have established at least during these two limited centuries.
Moreover we can find difference between both of the titles of the government post. While the complier of the Chronicle of Japan said that the title of Yamato tribe was the Atai, that of the Kojiki described it as the Kuni-no-miyasuto. It is said that the Atai was bestowed to local authorities, which had been sometimes titled the Kuni-no-miyatuko, by the Yamato government from the 5th to 6th century. Does this mean that the Chronicle of Japan or the predecessor from which the complier referred was edited in the period?
The Kojiki, strange to relate, inserted the story of Saone-tu-hiko the ancestor of Yamato-no-kuni-no-miyatuko boarding on a shell of a turtle, who, in the Chronicle of Japan, was referred as the earthy deity of the Hayasuinato port, fishing on a boat, and changing his name from Uzu-hiko to Siine-tu-hiko granted by the Sumera-mikoto.
The complier of the Chronicle of Japan coincides with that of the Kojiki in the point that the next place of the sojourn of the Sumera-mikoto was the Palace of Takashima of Kibi-no-kuni, locating now in the Okayama prefecture. In detail, however, we can find some differences between both of history books. The former says that they stayed there for three years building more ships and stocking military provisions for reigning over the whole country, the latter only states that the term of their stay was for eight years.
From the Chronicle of Japan, leaving the port Oka, the party of the Sumera-mikoto went towards the East and in November 27th arrived at the palace of Ee of the Aki-no-kuni, where is regarded to locate in Hiroshima-prefecture at present. On the other hand, the complier of the Kojiki described that the name of the palace was Takeri, not Ee, and they stayed there for seven years.
