Sakhalin island

Sakhalin island between 1905 and 1945. The area south of the 50th parallel line was under Japanese control

From the signing of the 1875 Treaty of Saint Petersburg until the Russo-Japanese War which broke in 1904, the Russian Empire had full control of Sakhalin island. As a result of the 1905 Treaty of Portsmouth that brought an end to the Russo-Japanese War, the portion of the island south of the 50th parallel line became Japanese territory, part of Karafuto Prefecture. However, following the month long Soviet–Japanese War during the summer of 1945, the entire island was reunified under Soviet control.[4]
