Secondly, Nagasaki Gaidai University is the worst of the 8 foreign universities in Japan, not only is it a bad location, but the school is also predominantly for international students. Nagasaki is a remote area part-time work is okay, but Nagasaki Gaidai University is in the suburbs of Nagasaki, so part-time work may be a bit tougher. About 700 800 yen per hour
Finally, to give you a piece of advice, graduating from junior college in China is not possible to go directly to graduate school in Japan regular university is even more impossible, if it is a mix of education, this school can be, if you want to learn properly, you can go to Japan to specialize in education (3 years to compile) and then go to graduate school, and domestic specialization in education, undergraduate two years of the same set of rules.
I doubt that you really know Nagasaki Gaidai University, you can go to the homepage of Nagasaki Gaidai University to see if there is any graduate school set up. As far as I know, Nagasaki Gaidai University's so-called faculty students are basically domestic exchange students, and do not recruit faculty students in Japan itself. Also, for those of you upstairs, if there are really dozens of foreign language universities in Japan, could you please give me a list? As far as I know, there are only Tokyo University of Foreign Languages, Kanda University of Foreign Languages, Kansai University of Foreign Languages, Kobe City University of Foreign Languages, Kyoto University of Foreign Languages, Nagoya University of Foreign Languages, Nagasaki University of Foreign Languages, and Osaka University of Foreign Languages (Osaka University, Faculty of Foreign Languages). If you're talking about vocational schools and language schools, that's pretty much it.
