Mochi (Japanese: 餅; Chinese: ) is a Japanese rice cake made of glutinous rice pounded into paste and molded into shape. In Japan it is traditionally made in a ceremony called mochitsuki. While also eaten year-round, mochi is a traditional food for the Japanese New Year and is commonly sold and eaten during that time.

Mochi is similar to the Chinese rice cake nian gao; however, mochi is shaped from cooked glutinous rice right after it is pounded, whereas nian gao is steamed directly to its final form from a batter made of uncooked glutinous rice flour. In the Philippines, it is called palitao in Tagalog and is coated with sesame seeds and grated coconut.

Mochi is very sticky and somewhat tricky to eat. After each new year, it is reported in the Japanese media how many people die from choking on mochi. The victims are usually elderly. Because it is so sticky, it is difficult to dislodge via the Heimlich maneuver. In the Japanese comedy film Tampopo, a vacuum cleaner is used to suck it out (some lifesaving experts say that a vacuum cleaner is actually efficient for stuck mochi ).
