Kinoko no yama

 is a Japanese snack food produced by Meiji Seika. It is made in the shape of little mushrooms. Kinoko means "mushroom" and yama means "mountain". The "stem" of the mushroom is made of a biscuit-type cookie and the top is made of chocolate. Although chocolate is the most common flavor, it may come in many other flavors. In the United States, they are known as Chocorooms.
It was first sold in 1975.
