I honestly dont really know about many of the stuff you talked about, but it seems that getting money in japan is not going to be so easy. Its like MMM says u have to go to classes u have to study and the work teaching (suposing u find work teaching) and translating.. u would have to go to an hospital really soon from exaustion... If i were u i would seriously consider learnig japanese very well until u are fluent and then try a scholarship or some program not to think too much about money and concentrate in the important things, your studies and the experience itself...
But like i said i dont have any information about many of the stuff you talked about...
