Sea lions inhabiting Moneron Island

Covering roughly 30 square kilometres (12 sq mi), Moneron reaches an elevation of 429 metres (1,407 ft) at its highest point. Its dimensions extend about 7.2 kilometres (4.5 mi) from north to south and approximately 5.5 kilometres (3.4 mi) across. The island lies around 41 nautical miles (76 km; 47 mi) distant from Nevelsk, a port on Sakhalin, and is positioned nearly 30 nautical miles (56 km; 35 mi) southwest of the main Sakhalin landmass, at the northeastern edge of the Sea of Japan. It stands as the sole island within the Strait of Tartary and does not support a permanent population. When visibility is clear, Japan’s Rishiri Island can be seen from Moneron.

History

Originally inhabited by the Ainu people, the island was called Todomoshiri, meaning "island of sea lions." In the 18th century, it came under the control of the Matsumae clan's daimyō and was referred to as Ishiyokotan. The current European name, Moneron, was assigned by French explorer Jean-François de Galaup, comte de Lapérouse, who named it after Paul Mérault Monneron, the expedition’s chief engineer.

Paul Monneron was responsible for charting the island bearing his name. The first accurate cartographic representation of Moneron was produced in 1867 by Russian hydrographers during an expedition led by K. Staritsky, who lent his name to the island’s highest peak.

Following the conclusion of the Russo-Japanese War (1904–1905), sovereignty over Moneron passed to Japan along with southern Sakhalin below the 50th parallel, as stipulated by the Treaty of Portsmouth. By 1907, the Japanese designated it Kaibato (海馬島), integrating it into the Karafuto Agency until World War II ended. The name Kai-ba represents an on-yomi reading derived from the Ainu term. Another appellation used was "Todojima" (トド島), directly reflecting the Ainu word for sea lion combined with jima/shima (島), meaning island in native Japanese kun-yomi.

During Japanese administration, Moneron experienced both intense natural resource exploitation and notable infrastructure development. Permanent settlement began in earnest in the 1910s; one surviving structure from 1910 dates back to this period. A meteorological station established then remains operational today. Additionally, an underwater telephone cable exceeding 50 km connected Moneron with Sakhalin. In 1914, a lighthouse was constructed and continues to function. The island’s economy centered on logging and fishing, with Pacific herring (Clupea pallasii) playing a significant role. By the mid-1920s, a wooden shelter was built at Chuprov Bay’s southern shore to serve as a refuge for a small coastal fleet; this was later replaced with a concrete facility in the 1930s. To accommodate settlers’ spiritual needs, a modest Shinto shrine was erected in Krasnaya pit amidst ancient fir trees.

By 1936, Japanese residents numbered approximately 900 on Moneron; including seasonal maritime workers during earlier decades, total inhabitants reached up to 2,000 in the early 1920s. Rice cultivation took place near Kologeras Bay on the northern cape during this era; remnants of irrigation systems remain visible today. However, initial overexploitation led to a sharp decline in fish stocks by the mid-1920s, prompting many settlers to leave. By 1945, only around 200 people remained.

Throughout World War II, Moneron held strategic significance for both Japan and the Soviet Union. Notably, Soviet military records from their Far East operations in 1945 omit references to capturing Moneron despite unmarked Soviet soldiers’ graves being present on the island.

Post-World War II, Moneron was incorporated into the USSR’s Sakhalin Oblast. After 1946, its European name “Moneron” was reinstated. The island’s economy revolved around a fish processing plant located in southern Chuprov Bay that supported local fishing communities. According to the 1959 census, over 500 residents lived permanently across three settlements: Moneron, Krasny, and Bodry. Seasonal workers increased population numbers up to 2,000 during spring and summer months. However, from the late 1950s onward, Sakhalin’s fishing industry shifted focus toward more lucrative ocean expeditions. This transition led to closure of Moneron’s fish factory and subsequent population decline. Until the mid-1960s, teams from Nevelsk harvested fodder on Moneron’s luxuriant vegetation. Oil exploration took place until early 1970s but caused environmental damage. During that decade, permanent habitation ceased as Moneron became designated a closed border area with limited military presence occurring sporadically. This depopulation ultimately benefited the island’s flora and fauna preservation.

KAL 007

Korean Air Flight 007, carrying 269 passengers and crew, circled Moneron Island twice before descending during its final controlled 12-minute approach and ultimately crashing into the Sea of Japan near the island's shore. This occurred after it was hit by a single air-to-air missile fired on 1 September 1983 from a Sukhoi Su-15 due to the aircraft's incursion into prohibited Soviet airspace. The exact location and the final distance from Moneron Island remain subjects of debate.

Fauna and flora

Moneron Island is renowned for its diving opportunities and birdwatching. Encircled by steep cliffs and rocky islets, it serves as a sanctuary for seabirds. The surrounding waters benefit from the warm Tsushima Current, which supports a rich variety of marine species typically found much farther south.

In 2006, tourist infrastructure was established to facilitate visits to the island. These amenities are managed by Moneron National Park, recognized as Russia’s first marine national park.Template:Fix/category
