I think if u are too proud to be an english teacher u loose the best job u could do in japan, cause if u be a teacher and good in english u only have to talk in english in ur lessons or with ur coleagues so u don´t have to learn the difficult language. But my cousin lived in japan, too, and he didn´t learn the language and he isn´t an english teacher^^ so there have to be a way u can master it
Maybe u should try as an translator for animes and mangas
