Definitely a bachelor's degree does go a long way in getting you a job in Japan. Without a bachelor's degree, a bare minimum would be a diploma and TEFL certificate of some sort.

If you wanto to find a job teaching Japanese in Australia, then you would need to be a native Japanese person. I used to study Japanese in North Sydney and even the beginner classes were Japanese nationals.

As most non-native English speakers want to be taught by a native English speaker, so too do most native English speakers want to be taught by a native of the country's language they are learning. How good is your Japanese? Why don't you just focus on trying to teach English rather than Japanese?

A bachelor degree in any discipline is enough to get a teaching job abroad. Obviously the more focused your degree is on education / teaching, then the easier it will be to gain employment upon graduation.
