Government Jobs

Hello,

I am studing urban planning in Australia, the job market here is not ideal and with a housing crisis on top my hopes for the future are pretty bleak. So I was just wondering what the requirements for employment with city councils are. How do I get a job as an urban planner (civil servant) with a japanese city council? Do I have to be born in japan to get a job in government? Do I have to be a citizen? or can foreigners on working visas be employed? Do the requirements change working at a federal or prefecture level?

Thank you
