Is it better to immigrate to Australia or Japan?

It is certainly much better to immigrate to Japan, which is the longest-lived country in the world. The social security system, medical level and education level are all in the forefront of the world, with a good living environment and a legal and fair system. Of course, these conditions are similar to those of Australia, but Japan is close to China in language, race and culture. To put it bluntly, if you live in Japan for five or six years, it will be difficult for others to know that you are a foreigner, but no matter how many years you live in China, you will always be an Australian.
