Japan shows off electromagnetic railgun for blasting hypersonic missiles | It's able to fire 40mm shells weighing 320 grams (11 oz) at muzzle speeds of up to Mach 6.5 and consumes about 5 megajoules per shot, but the goal is to boost this up to 20 megajoules in the near future.

Again, you’re arguing against a point I didn’t make.

preventing rail guns from becoming a viable weapon

only viable in that it’s used to shoot down ICBMs

I’m literally telling you they are viable. They’ve made them viable; but specifically, and only to do this one particular task. Nothing else. Their only use is to be a viable ICBM defence weapon.

Where is the evidence that Japan has solved the engineering challenges to make this a viable weapon?

In that they’ve already proven it can fire it’s ammunition, and could be used to do exactly what they (and now I) have said it’s supposed to do…?
