"All dialects in the Amami Islands are endangered today. In other words, the younger generation does not speak these dialects. Depending on the situation, they speak a local variety of Japanese or Standard Japanese instead.
Every dialect in the Amami Islands is endangered because Standard Japanese has more political, economical, and cultural power. If such imbalance of power continues, it will continue to be difficult, and unlikely, for younger people to choose to speak these dialects, which are not their first language."

Hara and Heinrich (2015)'s chapter in the Handbook of the Ryukyuan Languages discusses The Society for Okinawan Dialect Revitalization, est. 2000, which established an Uchinaaguchi kana orthography, published teaching materials, has conducted training for prospective Uchinaaguchi teachers, and has established a quarterly newspaper written only in Uchinaaguchi. Uchinaaguchi is taught as part of club activities in many elementary and high schools in Okinawa.

Classified as "definitely endangered" by UNESCO

"Younger Amami-North Okinawan speakers are L1 Japanese speakers, and L2 Amami-North Okinawan learners (most people under 40 who learn are involved in traditional Okinawan culture, like the theater, with a growing number of language activists). And basically no children learn it at home from their parents, though there have been efforts to establish a language nest."

"'Language nest' is implemented at the community level, though the government has issued statements that it is certainly not opposed."

It's not written until quite recently and speakers don't write much.
