I am a mainland student studying in Hong Kong. Can I go to Japan freely? How do I apply for a visa?

Let's just say it's possible. It depends on your personal and family financial situation. You can try to apply for a tourist visa in the museum of the Japanese Consulate General. If the visa is approved, you need to bring the following documents: China passport, Hong Kong identity card, student handbook or student ID card, birth certificate (with your parents and your name on it), financial proof of your parents and yourself in the last three months (such as time deposit slip). Bank statement, the amount of which must reach five figures or photos, please fill it out at 46th floor, Plaza 1 Phase, Central Road, Hong Kong.
