Kakuni (角煮) is a Japanese braised pork dish which literally means "square simmered".
Kakuni is a meibutsu (popular regional product) of Nagasaki. The origin of this dish is most likely Chinese, making it a form of Japanese Chinese cuisine, and it is similar to Dongpo pork, though not as heavy in sauce. During the Ming Dynasty and Song Dynasty, the main Sino-Japanese trading route existed between Hangzhou and Kyūshū. Many Chinese lived in major Kyūshū port cities, such as Nagasaki and Japanese in Hangzhou. Therefore pork was popularized in major Kyūshū cities.
