In accordance with the treaty, both Japan and Russia agreed to evacuate Manchuria and return its sovereignty to China, but Japan was leased the Liaodong Peninsula (containing Port Arthur and Talien), and the Russian rail system in southern Manchuria with access to strategic resources. Japan also received the southern half of the Island of Sakhalin from Russia. Although Japan gained a great deal from the treaty, it was not nearly as much as the Japanese public had been led to expect, since Japan's initial negotiating position had demanded all of Sakhalin and a monetary indemnity as well. The frustration caused the Hibiya riots, and collapsed Katsura Taro's cabinet on January 7, 1906.
