CORPUS OF TANG POETRY TRANSCRIPTS THAT REMAIN WITHIN PREMODERN JAPANESE DOCUMENTS

本研究的目的是在<th><th>日本近代以前（13 ~ 18世纪）的手写书籍和印刷书籍的空白处，发现唐代（7 ~ 9世纪）的中国诗歌，<th>并探讨这些珍贵的诗歌为何会在日本、何时到达日本、通过何种途径到达日本，以及它们为何会从中国大陆流失。例如，唐代诗人白居易的3000多首诗歌至今仍保存在日本，但这些诗歌却没有被发现<th>。有几十种是从中国失传的，只以碎片的形式存在于今天的日本。在日本流传的作品中，也有数百首因抄写错误和传播错误而与中国现在所知的有很大差异。通过收集整理日本各地的档案馆和公共图书馆中的文献，我获得了这些诗歌的实例，并阐明了它们是如何进口的，以及它们继续存在和消失的几个过程。因此，我认为，这次“图书交流”证明了日本和中国在唐朝（7 - 9世纪）及以后的文化交流<th>不仅限于传统的日本使节<th>，但在民间或沿海地区的层面上也经常和大量地进行。从这个意义上说，这项研究提供了中国本土所没有的材料，我也相信它对中国古典文学研究领域有重大的好处。

The present research involves discovering valuable Tang Dynasty (7^<th> to 9^<th> centuries) Chinese poetry written and remaining by chance in the blank portions of pages in premodern (13^<th> to 18^<th> centuries) Japanese handwritten books and printed books.Further, through this research study, I aim to consider why these valuable texts are in Japan, when they arrived, and by what means, as well as why they were lost from the Chinese mainland.For example, although more than 3000 poems of the Tang Dynasty poet Bai Juyi remain to this day, there are dozens that were lost from China and only exist in fragmented form in Japan today. There are also several hundred cases of works circulated in Japan being greatly different from those generally known in China today, due to copying errors and communication errors.By collecting and organizing documents kept in storage in archives and public libraries throughout Japan, I was able to acquire actual examples of these poems, as well as shed light on how they were imported and several processes involved in their continued existence and disappearance.As a result, I believe this "Books exchange" has proven that cultural exchange between Japan and China during the Tang Dynasty (7^<th> to 9^<th> centuries) and thereafter was not limited to the traditional Japanese envoys, but was also frequently and heavily done on a civilian or inter-coastal area level.In the sense that this research provides materials not available in their Chinese homeland, I also believe that it will have significant benefits for the field of Chinese classical literature research.
