1 Introduction

This article introduces the interdisciplinary nature of language ethnography, points out the gaps in the study of language ethnography in transnational immigrant communities, and explores the importance of studying language use, identity, and ideology of transnational immigrants from this perspective. Taking the immigrant communities inhabited by Chinese in the Tokyo circle of Japan as an example, this paper analyzes the possibility of carrying out linguistic ethnography research, the new methodology and the assumption of studying cross-cultural communication.

The Integration of "Language Factors" and Ethnography in the Study of 2-Language Ethnography

Explored the importance and methodology of language ethnography research in transnational immigrant communities. Emphasis was placed on the role of ethnography in enhancing researchers' understanding of the emotional and environmental complexity of participants. Language ethnography combines the theories and methods of linguistics and ethnography, providing a new perspective for studying language issues in the social domain. Hemmers' "Narrative Ethnography" focuses on the application of language in social life, emphasizing the integration of language and social life. The "SPEAKING" model he proposed covers multiple aspects of language phenomena, emphasizing the revelation of their social significance through the description of language phenomena. Saville Trook's "Ethnography of Communication" establishes a bridge between language code analysis and socio-cultural description, studying the dissemination patterns of language communities and their interactions with other cultural systems. Effective communication in ethnographic research requires a solid foundation in ethnographic work, using the perspective of local people to validate researchers' judgments.

Methodological integration and innovation of language ethnography in the context of transnational immigration

The study of language ethnography in the context of transnational immigration requires the integration of sociological and linguistic methodological tools to flexibly address complex issues. Researchers should "adapt to local conditions" and integrate and innovate methodologies based on the language and cultural status of different countries. Participatory observation and field notes are the core methods of language ethnography, where researchers delve into the daily lives and cultural habits of their research subjects by living together. Cooperative ethnography is an important direction for the development of linguistic ethnography, which reflects the language practices of research subjects in a deeper and more comprehensive way through cooperation between researchers and research subjects, as well as among researchers themselves. Reflexivity is one of the core methodologies in ethnography, aimed at enhancing the objectivity and social fairness of research. Language landscape research focuses on non conversational forms of language categories, such as fixed language landscapes, as well as linguistic phenomena in conversational forms. The combination of technology and ethnography in digital ethnography captures the language practices and cultural exchanges of immigrants in virtual spaces, which is a new field of transnational immigrant language ethnography.

Concept of Cross border Language Ethnography Using Chinese Immigrant Communities in Japan as Containers

Explored the study of language and ethnicity in Chinese immigrant communities in Japan, using the case of Zhiyuan Tuanji in the Tokyo metropolitan area. Zhiyuan Tuan Di is a large rental property that has attracted a large number of Chinese immigrants and formed a community with diverse language usage. Chinese immigrants in this community use languages such as Mandarin, dialects, Japanese, and English, forming a super diverse community. The research objectives include exploring the phenomenon of multilingual contact, the relationship between language and cultural identity, language education practices in families and communities, and social integration and cultural conflicts in multilingual environments. The research methods include field investigation, participant observation, semi-structured interviews, language event recording and analysis, digital ethnography methods, and language landscape recording. Through these methods, the research aims to comprehensively present the language ecology of the Zhiyuan community and provide empirical data and theoretical support for understanding language practice, cultural identity construction, and social integration in a multilingual environment.

5 Multilingual Ethnography: A New Linguistic Perspective on Cross border Immigration Studies

Multi point ethnography, proposed by Marcus in the context of globalization, is applicable to cross-border immigration research and emphasizes spatial breadth and temporal dimensions. Multi linguistic ethnography combined with linguistic research, with the freedom of time and space, focuses on multiple linguistic contexts within a single stronghold. This methodology enriches traditional multi-point ethnography and refines spatial feature classification.

6 Conclusion

Emphasis was placed on the importance of incorporating transnational immigrants into language and ethnic studies, using the Chinese immigrant community in Japan as a case study to explore the theoretical basis, methodology, and innovative points. At the same time, it points out the challenges of situational diversity in the study of language and ethnicity in immigrant communities, as well as the impact of differences in language communication among cross-border immigrants on research methods and significance. Future research is expected to fill the gap in language and ethnic studies in the context of cross-border immigration in other countries, injecting new vitality into this field.
