Amami Oshima — Subtropical Island Paradise

Amami Oshima is a large subtropical island 380km south of mainland Kagoshima, closer to Okinawa culturally and ecologically. The island is covered in mangrove forests (rare in Japan), surrounded by coral reefs for snorkeling, and home to endemic wildlife including the Amami black rabbit (アマミノクロウサギ, a 'living fossil' species). The ocean glows with bioluminescent plankton on moonless nights.

The island's Ryukyu culture (language, textiles, music) reflects historical ties to the Ryukyu Kingdom more than mainland Japan.
