Katsu Don
(カツ丼)
A popular Japanese food, a bowl of rice topped with a deep-fried pork cutlet, egg, and condiments. The dish takes its name from the Japanese words tonkatsu (for pork cutlet) and donburi (for rice bowl dish).
It has become a modern ritual tradition for Japanese students to eat katsudon the night before taking a major test or school entrance exam. This is because “katsu” is a homophone of the verb 勝つ katsu, meaning “to win” or “to be victorious”
