noun
okoshi; millet and rice cake snack
A traditional Japanese confection made by roasting grains (millet, rice, etc.) and hardening them with starch syrup and sugar; sometimes includes peanuts or soybeans.

The word おこし is derived from the verb 起こす (okosu, 'to raise'), possibly referring to the process of puffing or raising the grains during preparation. The exact historical derivation is uncertain.
