Any JIS spindle won't let Campy or other ISO cranks go on quite all the way and will thus add 2-3mm effective length to each end of the spindle.
All the JIS spindles are 12.9mm "thick" (measured across flats, 3mm from the end), while European ISO crank spindles generally measure 12.65 to 12.75, depending on brand and vintage. New vs. old Campy are all pretty close btw, from 12.7 to 12.75mm.
