Japanese believe strongly in the food and drink matching custom, so it is almost a given to have a small snack with your drink. However, since there is usually a delay between the time an order is placed and the food arrives, izakaya typically offered a small dish of food together with the customer’s first drink--a type of Japanese appetizer. This small dish whets the appetite while the food was being prepared, and was also a way for the kitchen to confirm that they had received the customer’s order. Over time, otoshi became a standard custom for some bars and other types of restaurants. Additionally, because patrons sometimes sit for hours nursing one or two drinks, otoshi are a way for an establishment to recover the costs of customers occupying space at a bar or izakaya for an extended period of time and just consuming drinks.
