There are only a couple things i'll be looking for.
-able to be long term in japan (like some people, i too would live there forever.
)
-Pays enough to raise a family in an ok area and live well. The better the living the better in general to be honest. But anywhere in japan would be a super super win win for me cuz that's my dream.
-promotion and such is possible so that improved living is achievable.
