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

长期维持旧封建秩序的大朋家族和小林川家族都被迫臣服于丰臣政府。然而，在丰臣统治九州地区的情况下，他们之间的政治立场存在显著差异。丰臣军入侵朝鲜凸显了这一差异，这一事实可以通过对以下城堡遗址的研究得到证实：丰臣军居住的高崎山城堡；小林家居住的那岛城和立花山城。对废墟的近距离实地调查也清楚地表明，两位领主如何以及在多大程度上接受了小田军和丰臣军共同制定的地面计划；他们的政治立场是在丰臣对九州地区的控制下。此外，对这些废墟的仔细检查也让人们对丰臣军入侵朝鲜的一些隐藏事实有了新的认识。

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.
