The Japanese version of the hot dog—Black Terra Dog—comes in a black bun.
They use edible bamboo charcoal powder to color the bun, which is over 30 cm long. It is one of the most popular street food in the Akihabara district of Tokyo.
Kimchi is also an ingredient of other dishes, such as gimchijjgae (kimchi stew), gimchiguk (soup), gimchibuchimgae (pancake) or gimchibokkeumbap (kimchi fried rice).
