It seems that you do not know enough about the whole process of studying in Japan. First of all, there are two ways to apply for studying in Japan. First, if you have a favorite school, you can apply for a material in official website, and an application form will be attached to the material. Fill it out and send it back, even if it is an application. If you are qualified for admission, you can go directly to the university, that is, the master's degree, but only if you pass the Japanese exam. Another way, in a language school in Japan, you can take the entrance examination and apply for a university with the results of the entrance examination, and then it is similar to the above, except that it will save a lot of things in Japan.

If you are in China and plan to come to Japan, you can find an intermediary at will to save yourself a trip, in case you make a mistake, your visa will be refused.

Second, a visa is a study visa. I haven't heard of a study visa. If there is, it doesn't matter. Your word is a study visa.

Third, the tuition fees of language schools are high or low, ranging from 500,000 to 800,000 per year. (35,000 to 60,000 RMB) In terms of consumption in Osaka, after all, Osaka is the second largest city in Japan, definitely higher than other cities, mainly housing. But if you work by yourself, you can be self-sufficient in tuition and living expenses. I'm in Osaka now. If the above is not clear, leave your QQ and talk about it in detail.
