China fought against Japan for 14 years, and India beat Japan away in one war.
During World War II, Japan, as one of the Axis powers, launched many battles of all sizes on the Asian battlefield, and the minions of its aggression not only reached China, but also spared other countries on the Asian continent. Japan can be said to be an all-out attack, occupying land and resources for its own country, and after falling deep into China, it still continues to draw troops to Southeast Asia. And soon occupied almost all the countries of Southeast Asia.
But Japan did not invade India, just fought a battle and ran away, is the Indian army so powerful? At that time, the situation in the European battlefield was scorching, and Japan thought that it had taken advantage of the loophole that Britain had no time to take care of, and sent 80,000 Japanese troops to invade India. But in 5 months, only 10,000 of the 80,000 Japanese troops remained, and the Japanese army paid the price for its arrogance and light enemy.
After the occupation of Burma, the Japanese army tried to attack India, which was the Battle of Imphal. However, the Japanese seem to have chosen the wrong point of attack, imphal on one side of the Manipur Mountains, on the other side of the plains. If the Japanese army captured Imphal, it could be condescending, from the Manipur Mountains all the way to the west, the Japanese army had a third of the soldiers a total of more than 30,000 people infected with malaria, dysentery, cholera, influenza and other diseases.
At that time, India covered an area of more than 4 million square kilometers and had a population of hundreds of millions. The Japanese estimated that leaving aside the British forces in India, it would take at least 300,000 troops to control all of India. Moreover, the domestic situation in India is complex, and the problems of race, religion, ethnicity and caste are extremely serious, which is a very bad mess. I'm afraid I'll carry a big burden on my back.
