The Japanese emperor (天皇） who is a symbol of Japan since the end of second world war. When Japan lost the war, it was occupied by GHQ. GHQ set the emperor as a symbol because Japan may start war again if he would remain the emperor. Therefor, now Japanese emperor don’t have strong authority.
After talking about the emperor, I became to want to know about him more detail. So I search it.
The Emperor take only 1800kcal. This is setted !! So, he have kept his body shape since he was a high school student. Because of his food control, he can stay in good shape. The cooks of the emperor take care of making heathy food. For example, they use within 10g salt a day.
