What are the procedures for emigrating to Australia or Japan? How to deal with it?

Japan is not an immigrant country. In principle, foreigners are not allowed to immigrate unless you marry a Japanese citizen and then apply for a residence visa in Japan.

Australia is a country of immigrants. But immigration is a very complicated matter, which is divided into many types and applies to different people. It can't be explained clearly in one or two sentences. Simply put, if you want to immigrate, you must have at least one of the following two conditions: either you are very rich, or you have excellent professional skills and are proficient in English.
