The archaeological research of imperial palaces and mortuary cemeteries in ancient East Asia.

本研究旨在揭示古代东亚地区随着皇宫的形成而建立的太平间墓地的实际情况。在这项研究中，我发现太平间墓地位于皇宫之外。笔者还发现，在宫殿的空间关系、殡葬墓地的位置、墓葬的类型等方面，都有一个共同的元素，那就是来自中国的元素，以及各国的其他原始元素。故宫殡仪馆的地位反映了古代东亚各国的民族意识和殡葬制度的差异。

This research aims to reveal the actual condition of mortuary cemeteries that were established with formation of imperial palaces in ancient East Asia. In this research, I find that the mortuary cemeteries were positioned outside imperial palaces. I also find that there is a common element which comes from China, and other original elements in each country in the spatial relationship of imperial palaces and the location of mortuary cemeteries, and the types of tombs. I conclude that the status of mortuary cemeteries of the imperial palaces reflects the differences of the national ideology and mortuary system of each country in ancient East Asia.
