Shikine-jima

Shikine-jima is a small volcanic island located approximately 160 kilometers south of Tokyo in the Izu Island chain. Part of the Fuji-Hakone-Izu National Park, this remote island covers just 3.9 square kilometers and supports a population of around 600 residents. The island was formed by volcanic activity and has been inhabited since ancient times, serving historically as a place of exile during the Edo period for political prisoners and criminals.

The island's primary attraction lies in its exceptional natural hot springs and pristine coastal environment. Jinata Onsen features outdoor hot spring pools built directly into the rocky coastline, allowing visitors to bathe while overlooking the Pacific Ocean. The island's rugged volcanic landscape creates dramatic cliff formations and secluded beaches accessible only by foot. Mount Kanzaki, the island's highest point at 109 meters, offers panoramic views of the surrounding ocean and neighboring islands.

Visitors can explore the island's network of hiking trails that connect various hot spring locations and scenic viewpoints. Ashitsuki Onsen provides another seaside bathing experience, while the island's small fishing village offers insights into traditional island life. Snorkeling and diving opportunities exist around the island's clear waters, particularly near the southern coastline where underwater rock formations create diverse marine habitats.

The best visiting period runs from April to October when weather conditions are most favorable for outdoor activities and ferry services operate more frequently. Summer months bring warmer ocean temperatures ideal for swimming and water sports, while spring and autumn offer milder conditions perfect for hiking and hot spring bathing. Winter visits are possible but weather can be unpredictable with rougher seas affecting transportation.

Access to Shikine-jima requires taking a ferry from Takeshiba Terminal in Tokyo, with the journey taking approximately 3 hours via regular ferry or 2.5 hours on the faster jet ferry. Services operate daily during peak season but reduce to several times per week during winter months. Tokai Kisen operates the primary ferry service, with advance reservations recommended especially during summer and holidays. The island has no admission fees, though individual hot spring facilities charge between 200-500 yen per person. Limited accommodation exists in small guesthouses and minshuku, making advance booking essential for overnight stays.
