How do I immigrate to Japan?

What does LZ do? First of all, we must know that Japan is a naturally exclusive country, not an immigrant country. If a foreigner becomes a Japanese citizen, there is a word in Japanese called "naturalization". If he wants to "naturalize" Japan anyway, unless he marries a Japanese or his wife, he must first establish the permanent residency taken away by his family before he can apply for naturalization.

However, it is said that it is difficult. As far as I know, some China people who are married to Japanese have lived in Japan for 10 years, but they still cannot obtain Japanese nationality.
