Naruhito(徳仁) (1960-) is the current monarch of Japan. He has been emperor since May 1, 2019.
Unlike other authorities, it has no historical revisionist character. In short, it is far from far-rightist and ultra-nationalists politicians in Japan. Rather, he is quite friendly to South Korea and he also indirectly expressed his negative stance on the constitutional revision led by the Japanese rightists. (This emperor's move is all the more meaningful. Because emperor is sacred to Japan's conservative right-wing forces.)
