The Study of the History of Trans-regional Contacts of Christianity in the Ryukyu Islands under Occupation by the U.S.Armed Forces

在本研究中，我解决了20世纪40年代后期冲绳基督教的大部分实际情况。这一时期的基督教史直到现在都是一片空白。我通过收集新的历史文献克服了这一点。而且，这项研究是第一个澄清宫古和八山基督教历史的研究。通过被称为基督教跨地区接触史的方法论，冲绳、宫古和八山的传教工作的关系变得清晰起来。此外，我还证明了整个琉球群岛的基督教是由于日本大陆、台湾和美国之间的跨区域接触而改变的。

In this study, I solved most of the Christian actual situation in Okinawa of the late 1940s. The history of Christianity of this time was a blank until now. I overcame that by collecting new historical documents. And, this study is the first one that clarified history of Christianity in Miyako and Yaeyama. By methodology called the History of Trans-regional Contacts of Christianity, relationship of the missionary work in Okinawa, Miyako and Yaeyama became clear. In addition, I proved that Christianity of the whole Ryukyu Islands changed by the trans-regional contacts between Japanese mainland, Taiwan and the United States.
