一般に前方後円墳は，畿内勢力を中心に構成されていた政治連合に加わった各地の首長たちが，この連合における身分秩序にしたがって営んだものと考えられているが，６世紀の関東地方では前方後円墳の造営に際してそれ以外の地域とは明らかに異なる基準が適用されたことになる。また小地域における大型前方後円墳の密集度からも，その被葬者は単なる領域的支配者としての地域首長であるばかりでなく，畿内王権がこの地方に数多く置いた子代・名代などの部や舎人などの地方管掌者としての性格をも併せもつものであったと考えざるをえない。関東地方に他の地域と異なる基準に基づいて数多くの大型前方後円墳が営まれた理由は，この地域が畿内政権をささえる経済的・軍事的基盤としてきわめて重要な地域であったこと，さらに畿内諸勢力の連合体としての畿内政権を構成する諸豪族がそれぞれにこの地域の在地勢力と結びついて支配の拠点をえようとした結果と考えられ，まさに畿内政権の構造的特質によるものと思われるのである。, When we compare the numbers of large, keyhole-shaped mounded tomb with a mound length of over 60m, built in various areas in the Japanese Archipelago in the 6th century, that is in the Later Ko fun Period, we see that the Kantô District contains the largest number by far. Classified according to the statutory provinces in the Kantô District, there are 97 in Kôzuke, 16 in Shimotsuke, 38 in Hitachi, 11 in Shimousa, 28 in Kazusa, 26 in Musashi, and none in Sagami, a total of 216 tumuli. Even in the Kinai District, which includes Daiō 大王, tombs, there are 20 in Yamato, 12 in Kawachi, none in Izumi, 2 in Settsu, and 5 in Yamashiro, a total of only 39 tumuli. In the Kibi District, there are 2 in Bizen, 1 in Bitchû, 1 in Bingo, and none in Mimasaka, a total of only 4. In the Tôkai District, there are 12 in Owari, and 7 in Mino. It is thought that the large number in Owari is due to special political reasons, that the power in this region played an important role in supporting the Keitai Daiō 継体大王 in this accession to the throne. Therefore, it is obvious that only the Kantō District was a special region with regard to the construction of later keyhole-shaped mounded tomb in eastern Japan.
Generally, keyhole-shaped mounded tomb have been considered to have been established by the chiefs of various regions which joined the political association centering around the power in the Kinai District, in accordance with the status order in this association. In the Kantô District of the 6th century, however, obviously a standard different to that of other regions was applied to the construction of keyhole-shaped mounded tomb.
Furthermore, from the concentration rate of large keyhole-shaped mounded tomb in small areas, it must be taken that the persons buried were not only regional chiefs who simply ruled their local territory, but who also had positions as the regional controllers of Be 部 groups, such as Koshiro 子代 and Nashiro 名代, or Toneri 舎人, who were positioned in large numbers in this region by the Kinai Government. The reasons many large keyhole-shaped mounded tomb were constructed under a standard which was different from other regions thought to be as follows: this region was extremely important as an economic and military base supporting the Kinai Government; various powerful families which formed the Kinai Government in association wished to tie up with the local powers in tke Kantô District to acquire bases of control. So the above circumstances may be considered to have come about from the structural features of the Kinai Government.},
