Nii-jima (新島) is a volcanic Japanese island in the Philippine Sea that is part of the Izu Islands. It is one of the Izu Seven Islands group of the seven northern islands of the Izu archipelago, and is located approximately 163 kilometres (101 miles) south of Tōkyō and 36 kilometers (22 miles) south of Shimoda Shizuoka Prefecture.

Nii-jima has an elongated shape, measuring approximately 11 kilometers (6.8 miles) long by 2.5 kilometers (1.6 miles) wide, made of rhyolite lava that gives the island its famed white cliffs and white sandy beaches that face the Kuroshio current.

The island's natural wildlife is well preserved as many oceanic species and birds migrate thorough the island including the Indo-Pacific Bottlenose Dolphins along with nesting sea turtles, and the occasional visiting manta ray, sperm whales and humpback whales.

Marine Sports[edit]

Surfing is best on the eastern coast at Habushiura beach, a 6.5 km long protected marine reserve overlooked by volcanic cliffs, and open water swimming (Niijima Open Water Swim at 1.5 km, 3 km and 4.5 km ocean swims) and triathlons are held on Niijima.


Nii-jima is 2 hours and 20 minutes away by jet boat from Takeshiba Sanbashi Pier, in Tokyo, operated by Tōkai Kisen. Tōkai Kisen also operates a 9-hour overnight ferry. The ferry leaves Takeshiba Sanbashi at 22h00 (23h00 in the summer months) and arrives early morning in Izu Ōshima (approximately 6h00), before continuing on to To-shima (7h00), Nii-jima (8h00), Shikine-jima (8h30), and Kōzu-shima (9h30). The ferry then returns following the same route, leaving Nii-jima at 12h00 and docking in Tokyo at 17h00. It is possible that in rough weather, the ferry is unable to dock in Nii-jima. There are daily flights, weather permitting, from Chōfu Airport located in western Tokyo. The flight takes approximately 45 minutes. Other ferries leave from Shimoda, Shizuoka Prefecture. Niijima-mura also operates a high-speed ferry between Nii-jima and Shikine-jima with 3 boats per day, and 4 per day in the summer months.

Prison Island[edit]

During the Edo period, Hachijō-jima and Nii-jima were used a prison islands as a place of exile for convicts. The practice was discontinued after the Meiji Restoration.
