After the Spanish-American War, the Germans assumed administration of the Caroline Islands. During 1914, during World War I, British warships shelled and destroyed the German colonial plantation owner's radio station. On October 7, 1914, a Japanese Expeditionary Squadron landed on Yap in a bloodless takeover. Afterwards, a secret treaty agreement
between Japan and Britain guaranteeing Japanese control over all Pacific
islands north of the Equator that became part of the Treaty of
Versailles during 1919.
By 1920, Japanese settlement began on Yap. After 1935, when Japan
left the League of Nations, the island was fortified during the late 1930's
into a military base. Yapese natives were forced to work in labor
gangs and at nickel, bauxite and phosphate mines on the island.
During the Pacific War, the
Japanese build a lighthouse at Gagil and intensive gardening begins
in a large portion of southern Yap. At the end of March 1944 Yap Island came within range of American B-24 Liberators that bombed the island until the end of October 1944.
