Study on the castle of Shokuho (織豊) period in Kyushu district

长期保持封建旧秩序的大友和小早川都被迫屈服于丰臣政府。但是，在丰臣控制九州地区的情况下，两者的政治立场却有着显著的差异。丰臣军入侵朝鲜后，这一差异变得更加明显。通过对以下城堡遗址的研究，可以确定这一事实：大友家居住的高崎山城堡;小林家居住的那岛城和立花山城堡。对遗址的近距离实地调查也清楚地表明了两位领主是如何以及在多大程度上接受了织田军和丰臣军制定的地面计划，以及他们在丰臣控制下对九州地区的政治立场。此外，对废墟的进一步研究也为丰臣军入侵朝鲜的一些隐藏事实提供了新的线索。

Both the Otomos and the Kobayakawas, who had long kept the old feudal order, were compelled to submit to the Toyotomi Government. However, there was a striking difference in the political position between them under the Toyotomi control over Kyushu District. The invasion of Korea by the Toyotomi Army made the difference stand out, which truth can be established by the research on the ruins of the castles listed below : Takasaki-Yama Castle, where the Otomos resided ; Najima Castle and Tachibana-Yama Castle, where the Kobayakawas resided. Close field surveys of the ruins have also made it clear how and to what extent the two lords accepted the ground plans developed by both the Oda Army and Toyotomi Army ; what their political stand really was under the Toyotomi control over Kyushu District. Besides, closer examination of the ruins has thrown a new light on some hidden facts concerning the invasion of Korea by the Toyotomi Army.
