1 Introduction

Regional studies have become a first level discipline, bringing new opportunities for Japanese studies in universities. However, there are issues of imbalanced talent structure and unequal distribution of research resources and resources. At the beginning of the 21st century, scholars proposed that Japanese studies should inherit innovation, expand horizons, and build collaborative mechanisms. The natural connection between Japanese language subjects and Japanese studies is crucial for their integrated development. The proposal of the integrated development mechanism of "one body, two systems" also has reference value for other foreign language disciplines.

The Development History of Japanese Studies in China and the Historical Status of Japanese Studies in Universities

Before the establishment of the People's Republic of China, Japanese studies had already received attention, and relevant research institutions were established during the Yan'an period. After the establishment of the People's Republic of China, Japanese studies experienced a period of development, with the reform and opening up in 1978 and the end of Japan's "Five Year System" in 1993 being two important dividing lines. The 1950s and 1960s were a period of recovery and development, with limited research institutions and personnel. In 1962, the Japanese History Research Office of the Tianjin Institute of History, Chinese Academy of Sciences, was established. In 1963, Mao Zedong gave instructions to strengthen foreign studies. In 1964, the Liaoning Institute of Japanese Studies was established. In the 1980s, Sino Japanese relations were important, and Japanese research entered a good period with an increase in the number of institutions. After 2000, the number of institutions rapidly increased, and language teaching institutions grew significantly. In the early 1980s, research focused on the successful experience of the Japanese economy, while in the later period, attention was paid to political conservatism. In the 1990s, there was a focus on political power and Sino Japanese relations. In the 21st century, research has deepened and focused on ethnic characteristics. Universities are the main force of research in Japan, with a large number of research institutions and personnel, a high proportion of research results, and the responsibility of talent cultivation. After the normalization of Sino Japanese diplomatic relations in 1972, Japanese language departments/teaching and research rooms were established in universities, leading to a wave of Japanese language learning. As of the end of 2021, there are over 400 regional and national research cultivation bases and filing centers in universities and research institutions across the country.

The necessity and inevitability of the integration and development of Japanese studies and Japanese language disciplines in three universities

Explored the necessity and inevitability of the integration and development of Japanese studies and Japanese language disciplines in universities. Firstly, the development bottlenecks faced by Japanese research were pointed out, including insufficient funding, imbalanced talent structure, single knowledge structure, and uneven distribution of research resources across regions. Secondly, it emphasizes the support of national education top-level design for the integration and development of regional national studies and Japanese language disciplines, such as the release of the "National Medium - and Long Term Education Reform and Development Plan Outline (2010-2020)" and the "Graduate Education Discipline Professional Catalog (2022)", which provide policy support for interdisciplinary integration and development. Finally, a "one body, two systems" integrated development mechanism was proposed, which focuses on the subject of "Japanese studies" and establishes interdisciplinary and cross departmental mechanisms for intellectual resource complementarity and sharing, as well as cross departmental, cross institutional, cross school, and cross regional mechanisms for information and knowledge resource sharing, in order to promote the innovative development of Japanese studies.

Ideas and paths for the integration and development of Japanese language disciplines and regional and national studies

Explored the ideas and paths for the integration and development of Japanese language disciplines in universities with regional and national studies. Firstly, it is emphasized that as an interdisciplinary field, regional studies should integrate resources from other disciplines and achieve collaborative development through the establishment of mechanisms and platforms. Secondly, it is proposed to establish a scientific and integrated development concept, build a multidimensional collaborative platform, and integrate university resources for comprehensive research in all aspects. Once again, starting from a broad perspective of regional and national studies, we aim to construct a "holographic" framework for Japanese research, emphasizing the importance of interdisciplinary basic research. Finally, it is proposed to break through research limitations and explore a new situation of "trinity" of micro, meso, and macro research, broaden research perspectives, and strengthen Japanese research from a comparative perspective of different countries. At the same time, specific ideas are proposed for the integration and development of Japanese language disciplines in universities with regional and national studies, including the establishment of an internal interdisciplinary integration development mechanism platform and the construction of cross school collaborative research and teaching mechanisms.

5 Conclusion

Wu Yan, Director of the Higher Education Department of the Ministry of Education, emphasized that the important goal of the reform and development of foreign language disciplines is the learning of knowledge and problem research in multiple professional fields based on professional language education. More than 500 undergraduate universities across the country offer Japanese majors, and the Japanese language discipline is facing the needs of reform and development. The diversity of professional research fields and in-depth academic research in the Japanese language teaching staff provide a solid foundation and important support for Japanese studies. The "Guidelines for the Construction of National and Regional Research Centers (Trial)" proposes that national and regional research centers should focus on strengthening discipline construction, cultivating emerging interdisciplinary fields, cultivating talents that meet major national policy research needs, and establishing research teams with professional advantages and significant influence. The development of Japanese language disciplines in universities in the new era requires adherence to tradition and innovation. The integration of Japanese language with regional and national studies is an important innovation in the field of Japanese language, and it is also a new source of broader and deeper development for Japanese studies in regional and national studies.
