Do you get key money back in Japan?

Excuse me, could you please clarify something for me? I've heard about the concept of "key money" in Japan, and I'm wondering if it's possible to get it back after a lease agreement ends. Is this a common practice, or is it more of a one-way payment that tenants make to landlords? I'm trying to understand the nuances of the rental market in Japan, and this particular aspect has piqued my interest. Thank you for your time and assistance.
