Tanaka just can't get strong. If he continues this way, he'd have to retire early, he won't make a living with sumo. Matsutaro, worried about Tanaka's future, thinks of an idea: Tanaka can open a "Chanko" (sumo stew) shop! Even if he fails at sumo, if he could open a first-rate chanko restaurant, his future would be secure.
