Amami Japanese

Amami Japanese (トン普通語, Ton-futsūgo) is a variety of the Japanese language spoken on the island of Amami Ōshima. Its native term Ton-futsūgo means "potato standard". Much like Okinawan Japanese, it is a descendant of Standard Japanese but with influences from the traditional Ryukyuan languages (in this case, Amami Japanese is influenced by the Amami Ōshima language).
