The first job I would recommend to you is being teacher. You´re coming from a country in which english is your mothertongue (or french? oO), it doesn´t matter at all, you can teach them at least adults who will probably never learn it perfectly so your skills after university should may be enough if you were skilled in english in high school. I don´t know what you learned in high school in english but the grammatic, communication and mediation skills should really be enough
Next is to be translator for some films, documents etc. if you are really skilled in japanese you can do that easily but you´ll sometimes need to know technical terms in japanese as well as in english, so that´s harder then being a teacher.
But I can´t tell you if the bachelor degree will give you such a big advantage, sure it depends on the job you want to take, but you can be sure that native japanese will apply for the job too and your language skills are more important. Even if you have your bachelor but can´t aski for a jack to repair your car or can´t offer some food or drinks you´ll have big trouble and maybe won´t find a job^^
When do you think people die?
When they are shot through the heart by the bullet of a pistol?
No.
When they are ravaged by an incurable disease?
No.
When they drink a soup made from a poisonous mushroom?
No!
It's when... they are forgotten.
