|Region||Yoronjima within the Amami Islands, Kagoshima Prefecture|
The Yoron language (ユンヌフトゥバ Yunnu Futuba) is a dialect continuum spoken on Yoronjima in Kagoshima Prefecture, southwestern Japan. It is one of the Northern Ryukyuan languages, which are a sub-branch within the Japonic language family. The language is one of the most endangered languages in all of Japan.
- Asato (/asi⸢tu/), Gusuku (/gusi⸢ku/ ～ /gusu⸢ku/), Ritchō, Kanō (/ha⸢noː/) and Nama (/naː⸢ma/)
- Mugiya-higashiku, Mugiya-nishiku and Furusato (/puru⸢satu/)
The Mugiya district is often considered to have a distinct form of accent and intonation.
According to Kiku Hidenori, who leads conservation activities, people of Yoron Island, Kagoshima Prefecture call their language "Yunnu Futuba." More precisely, a dictionary compiled by his mother Kiku Chiyo (b. 1927) gives /junnuhu⸢tuba/ as the word form of her home community, Mugiya-higashiku. Other words she collected include /junnu⸢jun/ (Yoron accent), /nizjancju⸢jun/ (accent of people of Mugiya-higashiku and Mugiya-nishiku), /sima⸢jun/ (speaking the dialect), /sima⸢guci/ and /simahu⸢tuba/ (the island/home community's language). Yamada Minoru (b. 1916) provides the word forms of the community of Chabana: /⸢ju⸣nnu ⸢fu⸣tuba/ and /⸢ʃi⸣ma ⸢fu⸣tuba/ (the island's language).
The following is the phonology of the Mugiya dialect, which is based on Hirayama et al. (1969).
- The null onset /∅/ may be added. It contrasts with glottal /h/ and /ʔ/.
- /h/ is [ before /i/, and [ before /u/. /hwa/ is phonetically realized as [ɸa].
- /si/, /se/ and [t͡ʃu] is realized as [ʃi], [ʃe], and [t͡su], respectively.
- [t͡ʃa], [t͡ʃu] and [t͡ʃo] are phonemically analyzed as /t͡ʃja/, /t͡ʃju/ and /t͡ʃjo/, respectively.
- [ʃa], [ʃu] and [ʃo] are phonemically analyzed as /sja/, /sju/ and /sjo/, respectively.
- N and Q are syllable codas (nasal and geminated stop, respectively).
The Yoron language has /a/, /e/, /i/, /o/ and /u/, long and short.
