Motherboard and PSU manufacturer's marketing department typically like to highlight the fact that they use Japanese capacitors, and there are even videos on Youtube and some articles about how to identify if a capacitor is Japanese.

Is there any conclusive evidence to suggest that Japanese capacitors are more reliable than, let's say, American capacitors?

You picked the wrong country for comparison. It is the Chinese/Taiwanese Capacitor plague that's relevant here: Epidemic of Faulty Capacitors from China --- “capacitor plague” – Dell laptops.
Supposedly the manufacturers have cleaned up their act, but trust comes hard to engineers after events like this.
