Ganryujima Island, also called Funoshima, is a small uninhabited island located in the Kanmon Straits between Honshu and Kyushu in Japan. The island sits approximately 600 meters off the coast of Shimonoseki in Yamaguchi Prefecture and measures roughly 10,000 square meters in area, making it one of Japan's most historically significant yet compact destinations.
The island earned its legendary status as the site of one of Japan's most famous duels. On April 13, 1612, master swordsmen Miyamoto Musashi and Sasaki Kojiro faced each other in a duel that has become deeply embedded in Japanese culture and samurai tradition. Sasaki Kojiro, known for his distinctive sword technique called the "Turning Swallow Cut," was defeated by Musashi, who famously arrived late and carved his wooden sword from an oar during the boat journey to the island. The island's popular name, Ganryujima, derives from Kojiro's sword school, Ganryu.
Visitors to Ganryujima can explore monuments and statues commemorating the historic duel, including dramatic bronze statues of both warriors positioned in combat stance. The island features walking paths, informational displays about the duel and the samurai era, and observation points offering views of the busy Kanmon Straits. The compact size allows for a complete tour within 30 to 60 minutes, making it suitable for a brief historical excursion.
Access to Ganryujima is exclusively by boat from Shimonoseki Port. Regular ferry services operate from the Karato Market area, with the crossing taking approximately 10 minutes. The ferry fare is typically around ¥600 for adults for a round trip. Admission to the island itself is free. The island has minimal facilities, so visitors should plan accordingly, bringing water and sun protection during warmer months. Due to its exposure to strait weather conditions, ferry services may be suspended during poor weather.
