Job in Osaka

I applied for an English teaching job in Osaka.
The job is not full time but part time.
I work at a school for nine hours on weekdays now.
The contract of the job in Osaka says that it is a six-hour job, but the salary is as much as I earn now.
I don’t want to work as a full time teacher because there are countless of work to do such as club activities, grading, and managing the classroom.
If I pass the interview, I will work in Osaka starting from April.
Living in an urban city is one of my dream, so I will do my best in the interview.
