If you want to work for only a few months, forget it. Visas are issued for work purposes for a minimum of one year. That is because most contracts last that long.
What kind of job did you have in mind? You will have to fulfill work visa requirements, and that usually means a minimum of a bachelor's degree plus a fair amount of Japanese language ability.
