Once upon a time, Mt. Hiei and Mt. Atago compared their heights with each other. At first, they were exactly the same height, however, as Mt. Hiei got angry and punched Mt. Atago in the head. Mt. Atago got a bump and won the competition exactly by the size of the bump. If you see any picture of Mt. Atago's ridge, you will recognize that there is a bump-like elevation on the top indeed.
The Atago jinjashrine (愛宕神社) stands at the summit of 924 meters high. The god enshrined here is said to be responsive for wishes of fire prevention. If you visit homes of any common house in Kyoto, you will see one or two talismans from this shrine adorned on their kitchen walls.
The crisp air around the peak surrounded by fresh greenery is very refreshing. It makes you feel that you are standing in the sacred realm of the god.
