Can I not go with my parents if I have a Japanese visa for more than five years?

Not less than 16 years old. According to the regulations on Japanese visa inquiry, applicants under 16 years old can only apply for a visa if they are accompanied by a guardian, that is to say, applicants under 16 years old must be accompanied by their parents or guardians to Japan, or a guardian can apply for a visa on their behalf. Have reached the age of 16, and meet other conditions for applying for a Japanese visa, you can apply for a Japanese visa alone without your parents' company.
