How does Japan immigrate?

Legal analysis: the applicant has a residence in Japan for more than 5 consecutive years. This is the most basic condition, which means that the applicant must have lived in Japan for more than 5 years. If he doesn't meet this requirement, he is not eligible to apply. Of course, applicants must have legal residence qualifications. The applicant's temporary departure from Japan or change of residence will not affect the application.

Legal basis: Article 9 of the Law of People's Republic of China (PRC) on Exit and Entry Administration. China citizens shall apply for passports or other travel documents when leaving or entering the country. China citizens who want to go to other countries or regions also need to obtain visas or other entry permits. However, unless the China government has signed visa exemption agreements with other governments or the Ministry of Public Security and the Ministry of Foreign Affairs provide otherwise. China citizens who leave or enter the country as seafarers and work on foreign ships shall apply for a seaman's certificate according to law.
