1) Please do not use this as a criterion for choosing a language school for the so-called Japanese Language School, such as Waseda University, Keio University, Kansai University, and Doshisha University. These outstanding specialty courses, such as Takushoku University Specialty Course and Takushoku University Specialty Course, are not registered in the Japan Association, but their teaching quality is very high, not to mention the visa success rate. You can ignore this selection criterion;
2) Excellent schools refer to students with relatively good management and an illegal stay rate of 3 or below 5. This involves the overall success rate of visa applications for students, which you can pay attention to, but this aspect does not involve any teaching quality issues, please note;
3) In the Kanto region, the Tokyo region has the most schools. Let me comment on the schools you mentioned. In fact, the guidance for students entering graduate school is usually one-on-one, so this aspect is generally Language schools will all provide it, usually just teaching you how to enter higher education or asking seniors to share their experience and application procedures with you, and there is relatively little professional guidance. Among the schools you mentioned, Guoshu and Meiros provide professional guidance in the arts, and also provide professional guidance for you. There is an Oriental Language Academy in Nishi Kasai. The art department also has professional art professors to provide guidance. It has art and design professional courses, including American, Russian, and Oriental languages. You can also go to the school website to view related courses; As you said, both Fuji and Sendagaya are very famous, but art tutoring is not your strong point and I do not recommend you to choose it;
The above content is for your reference. I hope your application will be successful and you will eventually be able to get into your dream field. Continuing your studies at the graduate school!
