Dunan (Yonaguni Ryukyuan) (3170-yoi) = Severely Endangered (100 percent certain, based on the evidence available) (“Many women come from outside the island, which further contributes to the replacement of Dunan by Standard Japanese. Within most Yonaguni families, the inter-generational transmission of the language has been long interrupted, and the total number of Dunan speakers is steeply decreasing.”)
