如今在日本公映的電影，其中日本影片所占比例過半，2008年以降的票房收入更常居外國電影之上。與歐洲、亞洲等諸國不同，國產電影處於優勢是日本電影市場的最顯著特徵。日本電影草創期的歷史情形則大為不同。與今天截然不同，市場幾乎被外國電影獨占。上映的雖為法國、義大利、丹麥、美國等國製作的電影，但大體都是經由英國進口的。日本的電影評論很少言及英國。這或許是因為，較之於法國、義大利、美國等國，所進口的英國電影極少，相關評介也就不太受關注。然而，若是不談作品內容與評價，將目光投向產業，若拋開英國，日本電影產業的形成發展就無從談起。本研究的目，即明析對日本電影產業的形成發展產生過巨大作用卻一直被忽視的日英電影交流史。為了探明電影產業草創期的日本企業在英國究竟有著怎樣的活動，本文以吉澤商店為例進行調研。以期勾勒出日英電影交流史的一個侧面，指明日英交流對於日本電影產業近代化的重要性。因此，這裡首先從日本、海外兩個方面考察日本電影產業，給吉澤商店以歷史定位，繼而尋訪偷敦的吉澤分店，最後考察為日本電影產業的形成發展貢獻巨大的日英交流之重要性。

The purpose of this research is to shine a light on the history of the film negotiations between Japan and Britain during the early 20th century. Even though these discussions have not been studied closely, they played a significant role in building the foundation of Japan’s film industry. In this paper, I will focus specifically on Yoshizawa & Co. (吉澤商店), which was an important institution during the early period of Japan’s film industry. Using Yoshizawa & Co. as a case in point, I will trace the beginning years of those Japanese companies, which operated in Britain in order to supply films for the growing number of movie theatres operating in Japan. By highlighting this one example of negotiations between Japan and Britain, I aim to elucidate how essential such discussions were to the modernization of Japan’s entire film industry. By casting a light specifically on Yoshizawa & Co., one can understand the formation and development of the early phase of Japan’s film industry. Based on newly-discovered source material, I will retrace the path Yoshizawa & Co. took in London. Lastly, I will reconsider the important role that film negotiations between Japan and Britain played in establishing and developing Japan’s film industry in general.
