William M. Vories, born in the USA, 1880, came to Japan in 1905. He, as a missionary architect, had performed architectural works not only in Japan, but also in East Asian courtiers. This study aims to clarify his architectural works focused his drawing archives of the architecture in China. Through surveying of those archives, we could find out his brainstorming sketches. Furthermore those sketches showed what kind of notions he had initially on plan proposals clearly, also blue prints showed the proof of cooperation with other architectural offices in this province. Through the analysis of the archives, it was made clear that the description in drawings had written in English first and then added translation of Japanese. We could read that these drawing show Japanese styled room positively from the 1930s. The reason was thought that his works at that time would have developed for Japanese Christian companies in Manchuria.
