According to the Kokon Hyaku Monogatari Hyōban from the Edo period, there is the statement "the people of the capital, or people of the name of a samurai, encounter this calamity and pass away (" If one encounters a kamaitachi, since there are medics who are familiar with this, they would rub some medicine on it healing it, so one would never die from it. In the northern parts of the country, it is cold in the shadows, weakening things. As it is cold in the northern parts of the country, cold wind blasts gather around, and the air is intensely cold. Borrowing this, they are said to be the deed of chimi in mountains and valleys. It is said that the reason why people don't receive this wound in the capital is because of the principle that malice does not win against true spirit.
