Why didn't Japan fight Macao?

The reason why I don't play Macau is because of Portugal!

Brazil is a colony of Portugal. Macao is also a colony of Portugal. What does this have to do with Japan's non-aggression against Macao? Good question! I thought there were a large number of Japanese expatriates in Brazil. If Japan attacks Macao, it is equivalent to declaring war on Portugal. All his expatriates in Brazil will be repatriated and their safety will not be guaranteed.

This has a profound historical origin. Back to the end of19th century, Brazil talked about it.

Brazil is the largest country in South America, and it is also a country with a vast territory and a sparse population. Brazil became independent from Portugal in the19th century. In order to build a new country, Brazil needs a lot of manpower. But Brazil had a small population at that time. There is a serious shortage of labor. So Brazil began to plan to introduce immigrants from populous Asia. At first, I applied for the Qing dynasty, but I didn't agree, because the colonial past had to be changed to Brazilian nationality. How can I, the people of a big country, be a second-class citizen in that strange place? So politicians decisively refused. At that time, I asked Japan to introduce immigrants (because there was a crisis in their country, there was no land to grow, and people sold their children and women in exchange for food). Later, the Japanese-Qing War happened, and then the zhina War of 15, that is, the eight-year war of resistance in our history books, actually 15). Japan agreed and began to immigrate a large number of Japanese to Brazil. There are many Japanese in Brazil now.

During World War II, Macao was Portuguese territory and Portugal was a neutral country. So Macao is also neutral. But this is not the reason why Japan does not occupy Macao. In fact, it was Brazil that helped Macao. Brazil sided with Portugal and warned Japan that if Japan occupied Macao, the Japanese in Brazil would be retaliated. Moreover, Macao's port is shallow, and its seaport status has long been replaced by Hong Kong, so Macao has no strategic position. So Japan didn't move Macao.
