English and Portuguese Teachers in Japan

[lineartube]

Hi. I'm seeking advice from teachers in Japan, for some friends of mine who just finished their course recently and are certified in teaching Portuguese, and English as a foreign language.

The problem is that around here, in Portugal, the Universities don't take in account if a job market is saturated, when they created new courses, so they graduate people in large batches and right now things are bad if you are a teacher in Portugal.

So I have this two friends, who are sisters, that are currently unemployed and they have a fascination about Japan and during a conversation with them I asked them why not try a offshore adventure, like for instance, in Japan? They got a bit interested but they don't have any knowledge of how to go about teaching in Japan, so I promised I would try to get some information for them.
Can anyone help me with this? Like writing about your experience as a teacher or recommending a company or how to go about and do this?

Thank you in advance.
