abstract:is a Japanese stew (a type of nabemono or one-pot dish) commonly eaten in vast quantity by sumo wrestlers as part of a weight-gain diet. It contains a dashi or chicken broth soup base with sake or mirin to add flavor.
Just as boxers suffer brain damage, so sumo wrestlers often pay the price for years of gorging on chankonabe, their special high-calorie pork, potato and anything-else-in-the-refrigerator stew.
