Japan generally requires a deposit, usually 200,000 yuan.
School application is very simple. As long as the school wants to admit you, it will give you admission permission. The key is your visa. If the deposit is not provided, the visa may not be successfully signed out.
Suggestion: Make a certificate of 200,000 yuan. If your liquidity is limited, you can go to the Bank of China, where there is a loan for studying abroad, which is very convenient.
