In the “300,000 Foreign Students Plan” presentation, generally visa standard alteration, as the lowest entry line to a country, before entering the country there are 150 hours of Japanese language learning experience (school admittance certificate is required ), Japanese Language Proficiency Test level 4, or otherwise scoring 400 points in the J.TEST is desirable. It can be said that this is the lowest degree of Japanese possible.
The idea is not to “somehow manage”, but to make the objective clear; this is a shortcut to improve Japanese language skills.
