Yes. Japan fought against the US, Britain, and China in World War 2.
World War 1 was fought against primarily Germany.
The British Commonwealth, France, US, Russia, Poland, and China were the Allies. They fought against the Axis- Germany, Italy, and Japan.
they withdrew to Taiwan to keep their Republic of China as People's Republic of China became to the dominance of the world; that's why Western World, especially Americans think Taiwan is an independent country, because they want to seperate it from China as Nationalists control the island and Communists control mainland.
World War 2Another answer:China also fought in World War 1. They sent a division to Europe. They kicked a German Colony out of China.They fought in the Korean War against the United States.

America fought the Pacific War with a strategy called island hopping. This was when America would fight the Japanese off of an island, and then use that island to target the next island. The island battles were horrifically brutal, as the Japanese fought till the death.
