Emergency contact, why is so hard to get one ?

I just moved to Tokyo a few weeks ago and right now I’m applying for an UR apartment, the only thing I haven’t been able to get is an emergency contact and I’m not sure why is so hard.

The company I’m working for told me they can’t provide it, I asked my coworkers and everybody rejected me telling me that they just applied for a PR, or that they are only a contractor or just by saying that might break the rules… maybe there is something that I don’t know but I told them that this is temporary and I can update my contact in a few months when my family gets here

As far as I know they don’t have to do anything but sharing me their contact information (email, address, phone).

Maybe there is a service I can hire for someone to be my emergency contact ?

EDIT: Thank you all for your comments I hired the service from japancontact
