Historically, Chinese characters were used throughout the East Asian region, giving rise to a common cultural sphere. Since early modern times, the written languages of East Asia have developed in a diversity of ways, shaped by nation, geography and culture, among other factors. Strengthening research on the long-term history of East Asian cultural development is thus very necessary. Komine Kazuaki has long been engaged in the study of medieval Japanese literature. Over the past two decades, he has projected a holistic academic approach to the study of culture in East Asia, conducting comparative research on the classical East Asian cultures. This paper takes a methodological approach to the discussion of the subjects, methods, techniques and goals of such research. In the study of East Asian cultural exchange, comparison enables us to undertake holistic investigations; it is not simply a tactic for unilateral studies. The study of texts and of images can be mutually enhancing; for example, the Japanese emaki is a medium that mixes literature and painting. Methods of researching environmental literature provide new insights for re-interpreting classical and modern literary works. Lastly, we need to examine the value of classical East Asian literature from the standpoint of East Asia as a whole; this is an urgently needed direction in contemporary research in this field.

从历史上看，整个东亚地区都使用汉字，从而形成了一个共同的文化领域。自近代以来，东亚的书面语言以多种方式发展，受国家，地理和文化等因素的影响。因此，有必要加强对东亚文化发展长期历史的研究。小峰和昭（Komine Kazuaki）长期从事中世纪日本文学的研究。在过去的二十年中，他提出了一种整体的学术方法来研究东亚文化，并对东亚古典文化进行了比较研究。本文采用一种方法论方法来讨论此类研究的主题，方法，技术和目标。在东亚文化交流研究中 比较使我们能够进行整体调查；这不仅仅是单方面研究的一种策略。对文本和图像的研究可以相互促进；例如，日本人emaki是一种将文学与绘画融为一体的媒介。研究环境文学的方法为重新诠释古典和现代文学作品提供了新的见解。最后，我们需要从整个东亚的角度来考察古典东亚文学的价值。这是该领域当代研究中迫切需要的方向。
