Chūhai, an abbreviation of "shōchū highball", is an alcoholic drink originating from Japan.
Traditional chūhai is made with barley shōchū and carbonated water flavored with lemon, but some modern commercial variants use vodka in place of shōchū, and beverage companies have diversified into a variety of flavors, including lime, grapefruit, apple, orange, pineapple, grape, kyoho grape, kiwi, ume, yuzu, lychee, peach, strawberry cream, and cream soda.
