Ways to work in Japan?

Hi, is there a way to work in Japan legally, Currently a foreigner but been dreaming to work in this country for a while now.

Unfortunately, It’s hard without a Working Visa But upon inquiring I need an employer who will sponsor it. Tried Student Visa but it’s expensive as hell, and we working holiday visa is not also an option also.
