Senkaku Islands Explained: History, Geography & What Travelers Should Know

Where Are the Senkaku Islands

The Senkaku Islands (尖閣諸島) are a group of eight uninhabited islands in the East China Sea, approximately 170 km (106 miles) northwest of Ishigaki Island. Administratively, they are part of Ishigaki City in Okinawa Prefecture — listed under the municipal address Tonoshiro Senkaku. Geographically, they sit at the edge of the Nansei Islands chain, between Okinawa and Taiwan.

The group is also known by other names: Diaoyu Islands (钓鱼岛) in China, Diaoyutai Islands (釣魚臺) in Taiwan, and historically as the Pinnacle Islands in Western maritime records. In Okinawan dialect, they are called iyukubajima (魚蒲葵島), and the local Yaeyama people know them as iigunkubajima — names reflecting centuries of regional maritime awareness.

According to the Sasakawa Peace Foundation, the total land area of the Senkaku Islands is approximately 5.6 km² (2.2 sq miles). The largest island, Uotsuri-shima, measures 3.63 km² with an elevation of 383 m (1,257 ft). The remaining islands are significantly smaller. None have permanent residents, infrastructure, or public access.

If you are planning a trip to Okinawa's islands, this article provides geographic and historical context. The Senkaku Islands are not a travel destination — they are uninhabited and closed to civilians.

A Brief History of the Islands

Early Settlement and the Meiji-Era Economy

According to the National Museum of Territory and Sovereignty, Okinawa Prefecture officials first landed on the Senkaku Islands in 1885 to conduct a survey. The Japanese government incorporated the islands into Okinawa Prefecture on January 14, 1895, after confirming they were uninhabited and not under the control of any other country.

From around 1889, Japanese fishermen had begun moving to the islands after recognizing that albatross feathers and great green turban shells were valuable export commodities. Around 1900, entrepreneur Koga Tatsushiro constructed a bonito fish processing plant on Uotsuri Island, employing over 200 workers at its peak. For a brief period, the islands supported a small working community.

The settlement did not last. By the early 20th century, the commercial operations wound down. According to the Sasakawa Peace Foundation, people lived principally on Uotsuri Island and Kuba Island as a result of private development, but the islands have been uninhabited since before World War II.

From US Administration to the Reversion of Okinawa

After World War II, the United States administered Okinawa Prefecture — including the Senkaku Islands — as part of its occupation of the Ryukyu Islands. According to Ishigaki City's official documentation, the Senkaku Islands reverted to Japanese administration in 1972 along with the rest of Okinawa Prefecture.

Since the reversion, the islands have remained uninhabited. The Japanese government has not permitted development on the islands, and no civilian access exists.

The Sovereignty Dispute in Context

The Senkaku Islands are the subject of a sovereignty dispute involving Japan, China, and Taiwan. Japan administers the islands and maintains that there is no territorial issue to be resolved. China and Taiwan both assert sovereignty claims over the islands.

According to the Ministry of Foreign Affairs of Japan, the islands are an inherent part of Japan's territory in terms of history and international law. China's position holds that the islands have been part of Chinese territory since ancient times. Taiwan makes a similar claim.

This article presents the competing positions without taking a side. For travelers, the key point is that the dispute is a diplomatic and political matter — it does not affect travel to Okinawa's other islands. Ishigaki, Iriomote, Yonaguni, and the Kerama Islands remain fully accessible and unaffected.

Why the Senkaku Islands Are Not Open to Visitors

The Senkaku Islands cannot be visited. There are no ferries, no flights, no ports, no buildings, and no civilian infrastructure. The islands have been uninhabited for roughly a century, and the Japanese government has not permitted the Ishigaki municipal administration to develop them.

This is not a temporary closure — the islands are simply not set up for any form of civilian access. Travelers researching Okinawa's islands will sometimes encounter the Senkaku name because of their administrative link to Ishigaki City, but there is no travel planning to be done here.

Where to Go Instead: Okinawa's Visitable Islands

Okinawa Prefecture offers a wide range of islands that are fully accessible and well-equipped for visitors. If you are exploring the Yaeyama region — where the Senkaku Islands are administratively located — these nearby islands deliver the remote, subtropical experience that draws travelers to this part of Japan:

• Ishigaki Island — The main hub of the Yaeyama chain, with direct flights from Tokyo, Osaka, and Naha. Beaches, snorkeling, and local Ishigaki beef. See our Ishigaki Island guide.
• Yonaguni Island — Japan's westernmost inhabited island, famous for underwater ruins and wild horses. Accessible by flight from Ishigaki (~30 min) or Naha (~90 min). See our guide to Yonaguni, Japan's westernmost island.
• Iriomote, Taketomi, and the Kerama Islands — Jungle trekking, traditional Ryukyu villages, and world-class snorkeling. All accessible from Ishigaki Port or Naha.
