If you're really interested in the language, the Yonaguni Ethnographic Museum sells a small dictionary written by an island auntie who is the museum's curator, Nae Ikema. The same woman, over 100 years old, is also the last remaining soul with a traditional knowledge of the island's peculiar writing system known as "kayida dii" (two symbols found carved in the underwater ruins closely resemble the local characters for horse and goat, respectively).
