Chances of this are not very good . About the only way to get work there is to have a skill a Japanese doesn't have . They will always be hired first .
What you might consider is getting a job as an ESL teacher . That would get you in Japan for at least a year . During that time you could check into getting the job of your dreams .
It would also give you enough time to find out if you even want to live there .
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
