Japan–Oceania relations

Before World War II, the Imperial Japanese Navy began construction of various airfields, fortifications, ports, and other military projects in the islands controlled under the South Seas Mandate. It was from these fortifications in Palau, the Carolines and the Marshall Islands that a significant portion of the Japanese Navy disembarked towards the Philippines, New Guinea, Nauru and the Gilbert Islands during 1941–42 in the Pacific War.
