The lack of any headstock angle is just the nature of the beast as far as those old japanese basses go. They just copied what they saw Fender do. Leo Fender was not a guitar player and had no idea how a guitar was actually constructed so when he designed his headstock he did it wrong, ever the engineer instead of fixing the problem and angling the headstock back he just added "string tree's"
or on the basses
Most of the Japanese instruments like yours used a simple bar to create the proper "break angle" over the nut
Anything you could add in there will do the trick. A piece of metal rod held down with two screws would be perfect.
I say shim the neck pocket, make some kind of string tree and play the thing. That is what it was made for after all.
