What preparations do China people need to make to settle in Japan? What things didn't I realize before I settled down, but I didn't know until after I settled down?

First of all, Japan is not an immigrant country. Although the Japanese government has gradually relaxed the immigration system in recent years due to the aging population, it is not easy to apply for immigration to Japan (permanent residence) on the whole. If you marry a Japanese, it takes 3 years, otherwise it usually takes 10 years. But here I offer two ways for talented or rich friends to use: rich people can take the form of investment visas, hire more than two people in Japan and invest more than 5 million yen a year (about 400,000 RMB, the money is still yours), so they can get long-term Japanese visas and live in Japan for a long time. To tell the truth, it is better to take this road if you have certain assets, because in China, individuals have an overseas remittance limit of 50 thousand dollars every year. If you have more money, it will piss you off. It will be different if there are companies in the two countries. Talented people can take the road of "contributing to the country". Of course, your contribution to Japanese diplomacy, art, culture and sports is another matter. I estimate that most people will make special contributions in the field of scientific research, with doctorates, published articles in international magazines and delivered speeches at international conferences. Then if you have a stable job in Japan, such as a university or a research institute, it is easy to get approval. This is the way my family goes (it takes more than 5 years in Japan, what does it mean to contribute to the country? See http://www.moj.go.jp/content/000096662.pdf, China Edition). What will happen? First, Japan is not as good as porn. Girls are more open, but comparatively speaking, I think the nightlife in China is much more colorful now. My residential area is as dark and quiet as the International Space Orbit Station at 8 pm. Second: Don't be intimidated by the service enthusiasm of city officials, and don't be flattered. Pretend nothing happened. In the service hall, there are usually staff standing waiting for the citizens to handle affairs. When you come, she will ask you what to do and help you find a form or something. If you need several officials to do several things at the same time, just sit still. The official who does this well will tell you that he is sorry and needs you to wait a moment. I will inform XXX to come to you. There is never the happiness of being a master on your face. Too corny. Japanese people usually look like "You are not doing well because I pay taxes to support you". Don't make a fool of yourself. Third, the ground in Japan is very clean. Don't be surprised to see children and even adults sitting on the floor everywhere. Fourth: the Japanese police smiled and saw that you were really laughing. Don't be afraid. Fifth: press the traffic lights when crossing the road. If there are no traffic lights, you should go to your boss, and the car will wait for you. Don't just wait there for the bus to pass by, the bus will wait for you. Every time I see the driver waiting for the bus getting impatient, I know that the pedestrian is from China. Sixth: slippers in other people's toilets are only used in toilets. Don't wear it. Seventh: Japan does not need to bring water and paper towels when going out. Paper can be obtained where it is needed, such as restaurants and toilets. Drink water. Find a small park or something. There's drinking water. If you don't like it, find a vending machine. It's corny. Eighth: neighbors try to say hello whether they know each other or not. Everyone does. Ninth: queue up if there is a queue, and queue up if there is no queue. In fact, everyone queued up quickly. Tenth: Japanese buses are the world of the elderly. They are arrogant and sometimes even "bully" you. You must make way. Think so much first, there is nothing to add.

Satisfied, please adopt.
