They did and were a centerpiece of why Japan thought it was the right time to go to war. Check out the link.

Germany and Japan were allies during World War 2. They were not at war with each other.
They were an ally of Japan
Japan went to war with many countries. In the Sino-Japanese war, they went to war with China. Japan invaded Taiwan in 1985. In the Russo-Japanese war, they went to war with Russia. In World War I, they were a part of the Allied Forces and battled against Germany and Russia. In World War II, they sided with the Axis powers, against The US, Britain, France, and other smaller Western European countries.
No, many countries in modern times tried to take pieces of China, and Japan invaded as part of World war 2, but China has always been China unless you go back to ancient times when there were several independent kingdoms and empires in the land that is now called China.
China
The U.S. supported China primarily to counter Japanese aggression in East Asia and to promote stability in the region during the 1930s. This support included economic aid and military supplies, as the U.S. recognized the strategic importance of China in the fight against Japan. The U.S. did not go to war against Japan sooner due to a combination of isolationist sentiment, economic concerns, and a focus on domestic issues during the Great Depression. It wasn't until Japan's attack on Pearl Harbor in December 1941 that the U.S. was compelled to enter World War II.
Possibly one quarter, if that. Japan had a lot of conquering to do. China's big, and when an army conquers a land, they must leave some troops their to "police" it. So Japan had to leave an "occupation" army in china (approximately one million men), and go else where to conquer more territory, with the men that weren't staying in occupied Manchuria.
Be more specific and if you mean in WWII that would depend if you count China
Japan
Yes. Ok?
