Hi,I'm 24 years old Japanese. Some friends High-School teacher for Chiba and my uncle is University hospital professor.

I asked them it.

1 need license for your country. 2 I think difficult. Because Full-time teacher is 08:00〜17:00 Basic needs. In many cases Part-time teacher. 3 4 maybe difficult. you must over time work and club or activity adviser for Full-time cases. 5 if you need this. University professor but Japan University is over pooling professor wisher. 6 this is ok. Because Japan all School need contract, above your country paid teacher salary.

7 sorry I don't know. but (come to Japan → search teacher job ) Not recommended You should be prepared if you use this means very cheap salary and part-time.

thank you.
