Other countries have constitutional monarchies. The UK still has an absolute monarchy, they just agree not to use any of the powers. They need a real constitution first to have a constitutional monarchy. (Instead they pretend a bunch of random historical documents are a constitution. At least one of them is a letter to the editor of a newspaper written under a pseudonym.)
Japan's monarchy was a Meiji invention; he had no power before that and has no power now. He's more like the opposite, a prisoner we specifically wrote into the constitution to have no human rights.
