It's ISO I doublechecked, it's an old MTB one, ProLogic in 109 width.
I also have a Gran Mighty ISO crankset on a Miche JIS with 0 problems.

All it takes is for to have been incorrectly installed once (too tight or too loose). The crank material is much softer than the BB spindle so will deform away from the ideal shape very easily.
Once that happens it's bin time.

Bin chainset.
Oh great... :(
How can I test for deformation? Just hold it next to the drive side I guess?
I guess this is bad...
Mondays...
