Is it difficult to return to Japan after naturalization?

It’s very troublesome. Naturalization refers to the general term in ancient Japan for people who immigrated to Japan from China or the Korean Peninsula and their descendants. It is also called immigrants. If a naturalized person wants to return to the country to visit relatives, it will be very troublesome, because at this time you are a foreigner. You need to apply for a visa, and you can only stay in China for 15 days.
