i dont really understand the work visa in japan i heard that if a job was willing to sponsor you you dont need to be in school to stay in japan
Its in english so i was wondering if they are directing this job posting towards gaijin and if they could and would sponsor me

Answer:

You need a four year degree to qualify for a work visa. This is what the Ministry or Foreign Affairs requires. The employer needs to sponsor the employee. This takes time & money. They're not going to do this when there's already people there who can do the job.
EDIT : it looks like a job to be a maid. And you might not get more than 15 hours a week. That won't be enough to live on. Sorry.
