[1] During October 1914, the Japanese sent vessels to occupy German colonies in the Mariana, Marshall, Palau and Caroline Islands.
Japan joined the war since they were already in an alliance with the British Empire and wanted to gain more territories.
[7] Another example was when the crew of the SMS Planet tried scuttling the vessel at the entrance of the harbor on Yap attempting to stop Japanese ships from getting in.
[8] A third example was when a sergeant on the island of Saipan rebelled against the Japanese marines that were landing by rallying the local police force and resist them on the beach.
Ponape in the Caroline's was captured on Oct. 7, although the territory’s surrender was delayed a few days due to a small local defence force that hid in the island’s interior to mount a resistance.
Japan made it plain that it did not welcome the entry of foreign ships into Micronesian waters, even those of its wartime allies.
