  • Self-presentation as an ELF user in social media: an analysis of Japanese young adults’ online language practices

     View Summary


    This paper delves into the identity constructions of Japanese young adults as users of English as a lingua franca on social media, with a specific focus on Instagram, a widely utilized platform among this demographic. Grounded in the premise that social media serves as a space for self-presentation, drawing from the social constructivist idea that the self is a performative act, the study centers on three Japanese young individuals with overseas experiences. It explores how they employ English as a communicative lingua franca in a transnational space while remaining highly conscious of their Japanese followers, endeavoring to portray idealized English-speaking selves. An ethnographic approach (Netnography) to the participants’ online practices involves prolonged online observations and interviews, seeking not only screen-based linguistic data but also uncovering the speakers’ voices behind the online screen. The findings illuminate that their identities as experienced English users evolves into a distinct aspiration to present themselves as competent English users. This aspiration is intricately attached to English ideologies, including native speakerism and the social status of English. The study provides valuable insights into the importance of scrutinizing the complex identity construction and language negotiation among speakers in ELF contexts, particularly within the realm of everyday online discourse. It sheds light on how young online users navigate between identities as English users and learners in the dynamic context of both global and local friendships.

  • ソーシャルメディアでの英語を軸とした多言語使用調査:エスノグラフィーを用いて


     View Summary

    By applying an online ethnography of Japanese youth language practices on social network services (SNS), the present research explored the young adults’ translingual repertoire, in which linguistic and non-linguistic semiotic resources are interwoven. The researcher conducted an extensive period of online observation of Instagram, questionnaire surveys, and multiple semi-structured interviews. The analysis illustrates their capability to exploit their available linguistic resources, including English, Japanese, Chinese, Korean, Portuguese, and German. They utilized these languages not only due to their comfort but also because of their desire to exhibit their local identities or express intimacy to their potential target audiences of numerous followers. Their language practices demonstrate their intricate identity formation in an online space where geographical boundaries transcend. Furthermore, they utilized diverse semiotic resources, including photographs, emojis, and hashtags intertwined with “named” languages. Their online language practices question conventional formal categorizations of what language is.Furthermore, the interview revealed that their online practices are intertwined with their offline experiences, including their friendships, language experiences, and language ideologies spread in the domestic society. For example, their language practices reflect linguistic beliefs such as language as an emblematic role and an asset to thrive in globalization. Furthermore, the participants are constrained by language prescriptivism, constructed through personal experiences, such as the entrance examination.The present research sheds light on translingual practices by Japanese youth, which has received limited attention by embossing the Japanese participants’ capability of using their repertoire ad hoc in an online space to express their translocal identities. Furthermore, it shows a complex interrelationship between their online language practices and their offline experiences and beliefs associated with languages.The research progress and outcome were/will be presented in the following academic conferences as an individual or co-authored papers: IAWE (International Association of World Englishes) in New York, U.S. in June 2023; Asia TEFL (Teaching English as a Foreign Language) in Daejeon, S. Korea in August 2023; JACET (Japan Association of College English Teachers) ELF SIG International Workshop in Tokyo in January 2024; Youth Media Conference in Vienna, Austria in March 2024; AAAL 24 (American Association of Applied Linguistics) in Texas, U.S. in March 2024. Two chapter contributions (one co-authored) to edited books, published from Akashi Shoten and DeGruyter respectively, are current in press.

  • ソーシャルメディアにおける自己表現媒体としてのELF(共通語としての英語)使用調査


     View Summary

    In the present research, the researcher applied only ethnography as a methodology to explore young adults’ translingual practices in online English as a lingua franca (ELF) communication. To do so, the researcher conducted an extensive period of online observation of Instagram, questionnaire surveys, and semi-structured interviews. The ongoing analysis illustrates the translingual capacity of the Japanese participants, who express themselves in front of their transnational friends. Their translingual resources become a vehicle through which the young adults expand and identify their potential audience and align identities with them.The analysis of creative translingual practices in the online ELF communication was presented in the following; Sociolinguistics Symposium 24 in Belgium in July 2022; the International Conference of English as Lingua Franca in Taiwan in November 2022; JACET (Japan Association of College English Teachers) ELF SIG International Workshop in December 2022; JASEC (Japanese Association for Studies in English Communication) Kansai Forum in January 2023; LINGUAPAX ASIA 2023, 11th International Symposium, International Christian University, Tokyo. My contribution to JASEC Bulletin Volume 30 was also published.

     View Summary

    Over the period, the researcher conducted a few months of online observation of the SNS platform, namely Instagram, questionnaire surveys, and interviews with online users. The ongoing analysis reveals that Japanese participants using social media exploit their translingual capacity creatively, expressing themselves using rhymes, metaphorical expressions, and other language plays. The analysis of questionnaires and interviews suggests that they often provide different identities depending on the languages. This research in progress embosses the Japanese participants’ creative capacity of using English for self-expressive purposes in the transnational online context.The textual analysis of Japanese undergraduate students’ creative English use, which is the core of this study, was presented at the Japanese Association for Studies in English Communication (JASEC), The 30th Annual Conference in October 2021. The manuscript of the contribution for JASEC Bulletin Volume 30 on this presentation is currently in progress. In addition, a book review on an edited book about creative writing in the digital age was published in Journal of Literature in Language Teaching volume 11(1). Finally, the abstract for the poster presentation on creative language use and self-presentation in social media was accepted and will be presented at Sociolinguistics Symposium 24 in Belgium in 2022.
