1, the difference of political rights.
Japanese citizens can participate in Japanese political power, including the right to vote and stand for election. They can join your favorite political party and run for parliament. Permanent residency is only the right to live in Japan. If you are not qualified to vote in the election, it is naturally impossible to enter politics.
2. Different entry and exit restrictions.
China does not need a visa for Japanese passports, but the period is only 15 days. If you need to stay in China for work or other reasons, you need to apply for a visa. You are still a citizen of China and can return to China at any time.
3. The cost of education is different.
Japanese children studying in Japanese universities can no longer enjoy the scholarship system for foreigners in Japanese universities and the policy of reducing and exempting university tuition fees. With the Japanese permanent residence permit (Japanese green card), children can still enjoy various preferential policies of Japanese universities for foreign students.
Extended data
If you want to apply for a visa to Japan, unlike the United States, which has an immigration bureau in customs management. There is no so-called immigration policy in Japan at present. Although the population of this country has dropped sharply because of the declining birthrate, it is still impossible to give up traditional etiquette and not accept immigrants. Therefore, there is no Immigration Bureau in Japan, and the agency that manages the entry visa procedures for foreigners is called the Immigration Bureau.
In recent years, Japan's relevant policies have changed, attracting foreign talents and expanding the number of international students on a large scale, and relaxing entry visas to some extent. But if you want to get a Japanese green card (permanent residence), I'm afraid it won't take a while, it will take more than ten years. Different from the United States, the United States generally considers the length of stay in China when applying for a green card, while the reference conditions for applying for permanent residence in Japan are not only the length of stay in Japan, but also the working status.
According to the conditions for the Immigration Bureau to apply for permanent residence, you must live in Japan for more than ten years and have eight years of work experience before you can apply for permanent residence. Frankly speaking, the conditions are harsh. There are rumors that there is a trend to reduce working hours to five to six years, but it has not been confirmed yet. After becoming a permanent resident, if you have a spouse or children, you can get a visa issued by the Immigration Bureau. This is called "permanent residence" in Japan and it is also a relative visa.
In addition, if "illegal stay" (that is, black households lose their visas) want to have a visa again, the only way is to marry a Japanese and get a Japanese spouse visa, which is also commonly known as "black to white". It is widely circulated among Japanese and China people. For example, after someone marries a Japanese, they get a visa, and then they get permanent residency, and then they get divorced.
