Yonaguni Island (Yonaguni Town, Yaeyama District, Okinawa Prefecture)

Overview (history, characteristics, attractions)

Yonaguni Island (Yonaguni Town, Yaeyama District, Okinawa Prefecture) is Japan's westernmost remote island, located approximately 110km from Taiwan, far from Honshu. As part of the ancient Ryukyu Kingdom, it flourished as a place of trade and maritime culture, preserving its unique language (the Yonaguni dialect) and customs. Its greatest attractions are its ocean and topography. The Yonaguni Undersea Terrain (Yonaguni Undersea Ruins), known for its vast array of formations on the ocean floor, is world-famous among scuba diving enthusiasts. The sunsets seen from Irizaki, Japan's westernmost cape, are iconic, and visitors can enjoy untouched nature, stargazing, and encounter endemic flora and fauna, including the Yonaguni horse.

There is a particularly high possibility of service suspension during typhoon season (June to October) and periods with strong swells, so be sure to plan your trip well in advance.
• Diving Safety：Many of Yonaguni's major dive sites have strong currents and are suitable for advanced divers. Check the dive site's experience, qualifications, and whether or not a guide is present, and do not push yourself too hard. Be sure to be physically fit and equipped, and follow the shop's instructions.
• Respect island life: Act quietly in the village, take your trash home, do not trespass on private property, and observe local etiquette. Respect the Yonaguni dialect and culture.
• Cash Situation/Shopping: There are some stores on the island that only accept credit cards, so it is a good idea to have cash (Japanese yen) on hand.
• Medical and insurance: Medical facilities and hospitalization facilities are limited, so if you have a chronic illness or are injured, you may be transferred to the main island.
• Consideration for nature conservation and living creatures: Cooperate in protecting the marine environment by not touching the coral or other living creatures, not feeding them, and not throwing trash into the sea.
• Cold weather and UV protection: There are days when the sea breeze can be strong. Bring sun protection and protection against the cold on the water (long sleeves, windbreaker, etc.).
