Why didn't Japan invade Brazil and Chile in South America during World War II?

The main causes of Japanese World War II were in China and the Pacific Ocean. Myanmar has put too many troops into attacking Brazil. It is said that once Brazil and other countries are attacked, many Japanese immigrants will be silenced by Brazil or taken hostage. Japan, the Soviet Union, the United States and other big countries, which were losing ground in China, opposed Japan's practice and sent troops to fight against it. Brazil is also a big country. Once we offend Brazil again, Brazil will send troops to fight against Japan with the United States, the Soviet Union and China. Japan, which was losing ground, lost a lot of troops. Once it joins hands, the consequences are self-evident? The failure of nature may even destroy the country. Japan always leaves itself a way out!
