Ainu is a moribund language, and has been endangered for at
least the past few decades. Most of the 150,000 self-proclaimed ethnic Ainu in
Japan (many additional Ainu are not aware of their origins or are secretive for
fear of discrimination)[citation needed] speak only Japanese. In the town of
Nibutani (part of Biratori, Hokkaido) where many of the remaining native
speakers live, there are 100 speakers, out of which only 15 used the language
every day in the late 1980s. The number of speakers today (by whatever
definition one may use) is not known with any certainty. In all of Hokkaidō, it
is estimated that there are perhaps 1,000 native speakers, almost all older than
30.[citation needed] Among Ainu speakers (broadly defined), second-language
learners presently outnumber native ones.
