I've used a Japanese toilet and for me the hand washing facility attached to it is meaningless as I do not understand why would anyone ever wash their hands with cold water. Especially I do not understand people who simply wash their hands by dipping them into cold water for a second.
But maybe the culture of washing hands with warm water and soap is merely in North Europe. And maybe I am illusioned by the effectiveness of warm water.
