International border From Wikipedia, the free encyclopedia
The Japan–Russia border is the de facto maritime boundary that separates the territorial waters of the two countries. According to the Russia border agency, the border's length is 194.3 km (120.7 mi).[1]
The two countries do not share a terrestrial border, although they did during the period 1905–1945 when the island of Sakhalin was split between Japan and the Russian Empire (and later the USSR).
The border between Russia and Japan has changed several times over the last 200 years. The Treaty of Shimoda (1855) divided the Kuril Islands, creating a maritime boundary between the Japanese Etorofu (Iturup) in the south and the Russian Urup in the north. The treaty did not determine the status of Sakhalin.[2]
The Treaty of Saint Petersburg (1875) assigned Sakhalin Island to Russia and all of the Kurile Islands to Japan. Thus during the following 30 years the maritime border between the two empires ran along the La Pérouse Strait (between Hokkaido and Sakhalin) and the Kuril Strait (between Russian Kamchatka and Shumshu Island in the Kurils).[3]
During the Russo-Japanese War, Japan was able to invade and occupy the whole of Sakhalin island over several weeks in July 1905. By the Treaty of Portsmouth, which concluded the war, Russia ceded the southern half of Sakhalin to Japan (incorporated as Karafuto Prefecture), while Japanese troops withdrew from its northern half; thus the two countries the first time in their history shared a land border, which ran along the 50th parallel north across the entire island of Sakhalin, from the Strait of Tartary to the Sea of Okhotsk.[4] Even though Japan occupied the northern part of Sakhalin in 1920–1925, during and after the Russian Civil War, Soviet control in the northern Sakhalin was established in 1925, and the 50th parallel became the Japan-USSR border.[5][6]
Since the Japanese Empire incorporated Korea by 1910, the short Korea–Russia border also became part of the border between the Japanese and Russian Empires, and later (until 1945), between the Japanese Empire and the USSR.
The land border in Sakhalin was crossed by the Soviet Army in August 1945, while Soviet marines landed in the Kurils. As a result of the short Soviet–Japanese War, the whole of Sakhalin and the Kurils became de facto (and de jure, under the Soviet law) part of the USSR, and of its constituent part, the RSFSR.[7][8] Even though the USSR and Japan reestablished diplomatic relations a decade later (the Soviet–Japanese Joint Declaration of 1956), no peace treaty or maritime boundary agreement between the two countries has been signed.[9]
The existing de facto (and, from the Russian point of view, also de jure) Russian-Japanese border follows several sea straits: the La Pérouse Strait, the Nemuro Strait, and Izmeny Strait (Notsuke Strait) and the Sovietsky Strait, which separate Sakhalin and the Kuril Islands from the Japanese island of Hokkaido. In Japan's view, the de jure border passes through the La Perouse Strait and the Vries Strait .
Japan claims the southern group of the Kuril Islands (viz. Iturup, Shikotan, Kunashir and Habomai), which were occupied by the Soviet Union in 1945 and incorporated into its Sakhalin Oblast. Russia treats the islands as an integral part of the country.
The Sakhalin-Hokkaido tunnel, or possibly a bridge, is a proposed 45-km(28 miles) connection to Russia's Sakhalin island and Japan's Hokkaido island. When the project is complete, it will span across the Soya strait and become the longest bridge in the world if it becomes a bridge. There, people can go to the other side by a railway or by a road.[10]
There are no border crossing points on the Russian-Japanese border, as it is a purely maritime boundary.
During the existence of the land border in Sakhalin (1905-1945), it was crossed by one road.[11]
However, when the Sakhalin-Hokkaido tunnel is complete, there will be checkpoints at the tunnel.
