Our Eunos Roadster has always had lazy seatbelts: They retract, but only if you give them no resistance. So when you get in the car and you have to ‘offer up’ the slack for the belt to tighten across you. If you don’t do this then the belt remains dangerously slack.

I located the fuse, thanks to the japanese word for “belt” shown on this page:
