Why didn't Japan invade Macao during World War II?

The only reason why Japan did not invade Macao in World War II was that Portugal, the ruler of Macao at that time, played a game with Japan through Brazil. "If we insist on invading Macao, Brazil will repatriate 3 million Japanese overseas Chinese in Brazil."

History should start from16th century. /kloc-In the 6th century, Portugal was a maritime hegemonic country. When they explored the new continent, they occupied Brazil and turned Bacina into their colony. In order to develop production, Portugal invited China, then in the Qing Dynasty, to develop South America for economic construction. In our country, people and officials are used to moving from other places and are unwilling to immigrate to this strange land of Brazil. Therefore, he invited Japan, which gladly went there and sent expatriates to Brazil. It accumulated to more than 3 million during World War II.

However, in the 1980s of 19, political corruption and people's livelihood were depressed in modern China. Portugal took advantage of the fire to rob and colonize Macao, becoming the actual controller of Macao. 1937, Japan started the Sino-Japanese War of 1894-1895, and China entered the all-out war of resistance. The Japanese also put forward a crazy plan to destroy China in three months, from the July 7th Lugouqiao Incident to the Xuzhou and Shanghai battles. China's army is losing ground, and the Japanese are pressing hard. 1942, the Japanese attacked Pearl Island in the Pacific Ocean and provoked the Pacific War, which was a brutal plunder of China and neighboring countries and regions.

Japan also wants to invade Macao. Portugal didn't want to see the situation of occupation, so it informed Brazil and Japan to negotiate in a game: "If it insists on occupying Macao, Brazil will repatriate 3 million Japanese overseas Chinese in Brazil." Considering the consequences and influence of the occupation of Macao, the Japanese invaders weighed it repeatedly and finally gave up the plan to occupy Macao.
