Yonaguni Island – Okinawa

Overview

Yonaguni Island is Japan’s westernmost inhabited island, located at the far edge of Okinawa Prefecture. It lies closer to Taiwan than to mainland Japan and is known for its dramatic cliffs, powerful ocean scenery, free-roaming horses, and a unique local culture shaped by isolation and cross-border influences.

Unlike Okinawa’s main tourist centers, Yonaguni offers a raw and rugged travel experience. It attracts visitors interested in unspoiled nature, underwater exploration, and Japan’s geographic extremes.

Geography and Natural Environment

Location and Landscape

Yonaguni is a small island measuring approximately 12 kilometers east to west and 4 kilometers north to south. The island is shaped by strong winds and ocean currents, resulting in:

• Sheer coastal cliffs

• Open grasslands

• Rocky shorelines

• Limited sandy beaches

The western and southern coasts are especially dramatic, with waves crashing against volcanic rock formations.

Climate

Yonaguni has a subtropical climate:

• Hot and humid summers

• Mild winters

• Strong winds throughout the year

• Typhoon season typically from July to October

Natural Highlights

Cape Irizaki (Japan’s Westernmost Point)

Cape Irizaki marks the westernmost point of Japan. It features:

• A simple monument and lighthouse

• Sweeping views of the East China Sea

• Spectacular sunsets

On exceptionally clear days, Taiwan may be visible on the horizon.

Free-Roaming Yonaguni Horses

Small, sturdy Yonaguni horses roam freely across fields and roads. They are a native breed once used for farming and transportation. Visitors should observe them respectfully and avoid feeding without local permission.

Underwater World and Diving

Yonaguni Monument

One of the island’s greatest mysteries lies beneath the sea: a massive underwater rock formation with sharp angles and step-like terraces. Some believe it to be a natural geological structure; others argue it is the remains of an ancient man-made monument.

The site is accessible only to experienced divers due to strong currents.

Hammerhead Shark Diving

From winter to early spring, schools of hammerhead sharks gather offshore. This phenomenon makes Yonaguni one of the world’s premier seasonal shark diving destinations.

Due to challenging conditions, diving is recommended only for advanced and certified divers.

Beaches and Coastal Spots

Kubura-bari (Kubura-furishi)

A narrow coastal passage where waves surge dramatically between rock walls. The spot has historical significance tied to legends of population control in the Ryukyu Kingdom era.

Hikawa Beach

One of the few sandy beaches on the island, suitable for swimming during calm conditions.

History and Culture

Ryukyuan Heritage

Yonaguni has its own language (Yonaguni-go), traditional dances, and customs distinct from mainland Okinawa. While the language is endangered, cultural preservation efforts continue through festivals and education.

Dr. Koto Clinic Filming Site

Yonaguni gained national attention as the filming location for the Japanese TV drama “Dr. Koto’s Clinic.” Visitors can see the preserved set, which has become a popular sightseeing spot.

Getting Around the Island
