Best way to study Japanese in Japan?
 

Hello Japan Forum.
I have some questions.

I am a 19 years old boy who just finished university and got a bachelor degree, and I want to search for a job in Japan. However I want to study japanese and hopefully pass the JPLT1 or JPLT2 before searching for a job, as being a freshly graduate not knowing any japanese, I will not find a job, but with homestudy while I study japanese in some years will be the best way to get a job.

At the time the plan is to save money so I can study at Yamasa Language Institute for two years, however it will take one-two years to save up this money, also two years with study.
So I will not find a job before four-five years, and I think this is to long.

Then my question is: Is there any place I can study japanese in Japan cheaper?
University have allways been free in my country if I got the criteria that is needed for the course, is this same with japanese universities?

I know I will have to pay for rent, food and other stuff to keep me alive even if I find a "free" university but it will make it a lot cheaper.

Also do you have any other tips that can help me study japanese in Japan for some years?
Any tips that you can give me would help, as a lot of japanese sites are in japanese(oh shock) so I can not get out any information.
