An occupied territory, sure. The Japanese only attacked the occupiers (USA). They didn't go after any of the native peoples' cities.

In 1887, King Kalākaua was forced to accept a new constitution after a coup d'état by the Honolulu Rifles, a volunteer military unit recruited from American settlers. Queen Liliʻuokalani, who succeeded Kalākaua in 1891, tried to abrogate the new constitution. She was subsequently overthrown in a 1893 coup engineered by the Committee of Safety (run by Sanford Dole), a group of Hawaiian subjects who were mostly of American descent, and supported by the U.S. military. The Committee of Safety dissolved the kingdom and established the Republic of Hawaii, intending for the U.S. to annex the islands, which it did on July 7, 1898, via the Newlands Resolution. Hawaii became part of the U.S. as the Territory of Hawaii until it became a U.S. state in 1959.
On geopolitical scale, you either need to have big guns or big friends. No one has any true right to any land. If you don't have the foresight to recognize that, you probably don't have a place in the future.
This isn't even something only cold imperialist superpowers adopt. Hawaii itself was populated with warring chiefdoms that were killing each other and taking land for centuries before a bigger fish showed up. Small fish happily eating smaller fish but then are upset when they get eaten...
