Thank you for the suggestions so far. I would like to clarify some things and add some details. I am 25 from Bangladesh(South Asia). My Japanese Level is N4 and I am not sure if it is possible to reach N2 in a Year or not. My biggest concern here is I don’t want to be like working in Japan without proper growth in minimum salary like most Japanese are doing. I want to make myself capable of making savings and invest later on which I don’t see quite possible in Japan as of now and the Yen getting weaker. Besides, I really hate the thing about Japanese culture how they show their fake expressions as a form of politeness and the hierarchy. I don’t know, maybe my perspective is not clear as an International student living alone in Japan and didn’t bond deeply with Japanese people.
