Tokyo Japanese Education Center (the only public language school in Japan), the accommodation environment is cheap but strict. There seems to be no special college counseling)
Fuji international language (but more stringent and louder in advertising)
Thousand Volts Valley Japanese College (this school is very strong because its legal person is different from other schools, and it is a joint-stock company with two independent teaching buildings and two other campuses, and has independent college entrance examination classes, which is mainly recommended). Chi Men Society Japanese School (an old school with two independent campuses, but the number of students in China has decreased in recent years).
Chinese martial arts Japanese school (Chinese martial arts is famous for its Japanese proficiency test books, and the school also recommends it)
Sanfeng Japanese school (this school is also good, I don't know much about it)
ARC Japanese school (this school is large and complicated. There are many school buildings, but most of them look like one or two floors. The university class also has a branch in Osaka (Shinjuku Campus).
Osaka area
Osaka Japanese Language Education Center (the only public language school with Tokyo Japanese Language Education Center)
JCL foreign language school (this language school in Kyoto is very strong, although the time is short, but the accommodation quality is high, so don't worry about the key recommendation)
Nagoya area
Nagoya seems to have ECC and YMCA, which are legal persons of many schools in Japan.
There are relatively few good universities in Nagoya. If you are sure to be famous, you can go to Nagoya. On the whole, it is recommended to go to Tokyo Language School, which has great opportunities for further study.
