Discussing "speakers of Japanese" is a challenging task. Already a quick look at the tables of contents of handbooks and introductions to sociolinguistics shows that "speaker" and "language user" usually do not appear as chapter titles. The term "language" dominates instead. Widely used introductions to Japanese language scantly state that "Japanese is the native language of virtually all Japanese nationals" (Hasegawa 2015: 3), or that "Japanese is currently spoken by approximately 127 million people in Japan" (Iwasaki 2013: 1). Iwasaki (2013: 1) further refers to kokugo (national language), "especially as the name of a school subject", versus nihongo (Japanese language), a term used when Japanese "is contrasted with other languages". Others elaborate that nihongo is commonly understood to be "what the Japanese people speak" so that it can be considered equivalent to kokugo. In the modern period, Japanese is associated with the standard or common language, "spoken (or speakable) by everyone everywhere in Japan" (Shibamoto and Smith 2016:In order to sketch an overview of "Japanese and its speakers", one first needs to dismantle the concept of "speaker", and then elaborate on the notion that Japanese is "speakable by everyone everywhere" in Japan. This leads straight to discussions of "non-native" users of Japanese, i.e., second language Japanese learners in Japan (henceforth, J2) and outside Japan (henceforth, JFL). 2The number of Japanese language learners in Japan was approximately 190,000 in 2015 (Bunkachō 2016: 57-58), while some 3,6 million learners studied the language outside Japan (Japan Foundation 2016a). 3
Speakers of Japanese: A terminological accountA common-sensical understanding of "native speakers" (henceforth, NS) refers to people speaking their "mother tongue" or "first acquired language". The concept of "native" is thereby contrasted with "non-native". This definition relates to lifetime. Learning a language in early childhood is what makes a speaker "native". Other definitions relate to competence. A NS has a "perfect" command of the language, making NS linguistic authorities in their native tongue. 4 Limiting our discussions to such idealized "Japanese NS" would be misleading. To start, Japanese-first language speakers (henceforth, J1) speak Japanese in various ways. Then there are J1 speakers outside Japan, and those who have learned Japanese side-by-side with another language, in various circumstances.Japanese is also learned as a second language (J2) and a foreign language (JFL). Japanese was also 2 enforced as a "national language" (kokugo) in colonial Taiwan and Korea, where many of the older
