Introduction
Yonaguni Island (与那国島, Yonaguni-jima) is the westernmost inhabited island of Japan, just 111 km from Taiwan. Famous for its mysterious underwater stone formations, wild horses, and breathtaking coastal cliffs, Yonaguni is a destination full of both natural drama and cultural depth. With fewer than 2,000 residents, it offers a quiet, authentic Yaeyama atmosphere far removed from mass tourism.
Highlights of Yonaguni
The Yonaguni Monument (与那国海底地形)
Discovered by a local diver in 1986, the “Yonaguni Monument” is an underwater stone formation with massive stepped terraces and sharp angles. Some researchers argue it is man-made ruins from a lost civilization, while others believe it to be a natural phenomenon. Either way, it is one of the world’s most fascinating dive sites.
Yonaguni Horses (与那国馬)
Yonaguni horses are a rare native breed, small yet strong, and deeply connected to the island’s history. Today they roam freely in pastures and along the coastline, offering visitors a glimpse into a living tradition.
Rugged Coastlines & Scenic Points
The island is ringed by cliffs shaped by the East China Sea. Cape Irizaki (西崎) marks Japan’s westernmost point, where on a clear day you can see Taiwan. Tategami Rock (立神岩), rising dramatically from the ocean, is a symbol of the island.
Culture & History
Yonaguni’s unique position as a border island has shaped its culture. Traditional songs and festivals show influences from both Okinawa and Taiwan. The island is also known for kusu (薬草酒), a strong herbal liquor, and for handwoven Yonaguni textiles.
