Language shift, code-switching, and linguistic change in a contested borderland
Objectives: This study investigates language shift, code-switching, and linguistic change in an understudied trilingual Japanese-Korean-Russian speech community on Sakhalin. It elucidates how successive political regimes, demographic transformations, language/dialect structure, and speaker proficiency shape diglossic relations, language choice patterns, and multilingual practices. Methodology: Using implicational scales, macro-level analysis visu…

Transplanted Brazilian Portuguese in Japan
This paper explores an emerging Brazilian Portuguese koiné spoken among Brazilian-dominant Latin American immigrants in Japan’s Greater Tokyo Area. It examines Strong-R (onset /r/) realizations by 79 speakers in the context of dialect and language contact within the diasporic setting. The results highlight (a) levelling and focussing towards [h] as a result of koineization and (b) early stages of the adoption of [ɸ], a xenolectal feature, resulti…
NPs in Japanese conversation
This paper is a discourse-pragmatic analysis of nominal phrases (NPs) that speakers of Japanese produce in informal dyadic conversational interaction. More specifically, it examines NPs in terms of their relations to 'intonation units
Diaspora Japanese
In introducing this special issue on Japanese outside of Japan, this article sets the scene by providing an overview of the genesis and trajectories of the Japanese diaspora which examines the history of international population movements, demographic transitions, educational orientations and language situations in the resulting communities. It touches upon: (a) the disappearance of the oldest nihon machi (Japan towns) formed by fleeing samurai a…
The vernacularity of Palauan Japanese
Through a qualitative and quantitative analysis of linguistic, perceptual, historical and sociodemographic data as well as two decades of sociolinguistic ethnography collected among the postcolonial Japanese speech communities of Palau in the Pacific, this article argues that Palauan Japanese was not simply 'standard Japanese transported', but a koineised vernacular variety of Japanese; i.e., a variety resulting from the mixture of different migr…
The maintenance of Japanese as a heritage language in Mexico
This article reports the first sociolinguistic investigation of heritage language maintenance in two distinct types of Japanese migrant community in Mexico City - pre-war labour migrants and recent self-movers. We investigate which social factors most strongly contribute to the preservation of Japanese oral language ability in these two communities. The results confirm the significant effects of languages used in the home and educational domains …
The role of social networks in the post-colonial multilingual island of Palau
This paper aims to reveal mechanisms of language maintenance and shift in the rural post-colonial multilingual island community of Palau in the Western Pacific, using social networks as an explanatory framework. I explore the usefulness of social networks from three perspectives, investigating whether and how social networks can explain changes in the use of former colonial languages in a post-colonial community; the functions of strong and weak …
Investigating the sociolinguistic gender paradox in a multilingual community
The focus of this article is the supposed “Gender Paradox,” proposed by Labov(1990,2001), which suggests that women are both sometimes conservative and sometimes innovative in terms of linguistic variation and change. Here we explore the paradox from two perspectives: we in vestigate both its applicability to multilingual as opposed to multidialectal communities as well as question whether the paradox is methodological or real. Although much soci…
Unit linking in conversational Japanese
Japanese intonation units and syntactic structure
This paper examines the preferred syntactic structure of the idea-conveying substantive “intonation unit” (IU) in conversational Japanese. It was found that (a) the clause is the syntactic exponent of the Japanese substantive IU; (b) the clauses are overwhelmingly single-IU clauses rather than multi-IU clauses; and (c) the multi-IU clauses exhibit a higher proportion of multiple new NPs than the single-IU counterparts. The results show that despi…
Intonation units, clauses and preferred argument structure in conversational Japanese
Intonation units and functional composition in Japanese conversational discourse
This paper examines informal face-to-face, two-party conversations in Japanese in order to explore the relationship between intonation units and functional composition. Specifically, the present study investigates the preferred functional structure of substantive intonation units that convey ideas of events, states, or referents. It was found that the Japanese substantive intonation unit preferentially consists of no more than two functional comp…
And-prefaced questions in institutional discourse
This paper presents a pragmatic account of and , a conjunction that iscommonly used by professional questioners as a question preface in institutional interactions. Based on some linguistic features characteristic of and -prefaced yes/no questions, it is argued that and -prefacing serves two main functions. It underscores a link to the anaphoric discourse (e.g. juxtaposition), thereby grouping the conjoined propositions as a coherent package of i…
