Whichever annals be correct--and the balance sways in favour of the Korean so far as those protohistoric eras are concerned--"there can be no doubt that Japan, at an early period, formed an alliance with Paikche" (spoken of in Japan as "Kudara," namely, the regions surrounding the modern Seoul), "and laid the foundation of a controlling power over the territory known as Imna (or Mimana), which lasted for several centuries." [Aston.] One evidence of this control is furnished in the establishment of an office called uchi-tsu-miyake in addition to the chinju-fu already spoken of. From early times it had been customary in Japan that whenever any lands were acquired, a portion of them was included in the Imperial domain, the produce being thenceforth stored and the affairs of the estate managed at a miyake presided over by a mikoto-mochi. Thus, on the inclusion of certain Korean districts in Japan's dominions, this usage was observed, and the new miyake had the syllables uchi-tsu ("of the interior") prefixed to distinguish it as a part of Japan. It is on record that a mikoto-mochi was stationed in Shiragi, and in the days of Jingo's son (Ojin) the great statesman, Takenouchi-no-Sukune, took up his residence for a time in Tsukushi to assist this mikoto-mochi and the chinju-fu, should occasion arise. Modern Japanese historians describe this era as the first period of Japanese national development, for an almost immediate result of the oversea relations thus established was that silk and cotton fabrics of greatly improved quality, gold, silver, iron, implements, arts, and literature were imported in increasing quantities to the great benefit of civilization.
