Hello, the passport is for you to go to the exit-entry administration yourself. It will take about 10 days to get out, and the fee is 200.

If you are invited by your Japanese friends, you can apply for a visitor visa, but both China and Japan need to provide materials.

You also need to take photos with your friends or exchange letters. The visa fee for visiting friends is about 450, and it takes 4 working days to sign.

If you go by yourself, you can apply for a visa to travel freely in Japan. You can show some assets certificates. Students at school can use their parents' assets certificates and pay a certain deposit. When you come back, you will be returned for a week or so.

Going to Japan for two weeks depends on whether you stay in a hotel or a friend's house and how you play, whether it's tourism or shopping, plus round-trip air tickets1-20 thousand or so.

If you have any questions, please contact me. Baidu HI or Space has my detailed contact information. Good luck.
