The story follows Matsutarou Sakaguchi, a giant roughneck man with strength far beyond ordinary people. He never uttered words like "work hard," "strive," and "dream" like the typical shonen manga protagonist. However, he is stronger than anyone and peerless in sumo wrestling. His greatest weakness is his own carefree personality. He grows into a full-fledged sumo westler.
Both series revolve around the National Sport of Japan 'Sumo'. They both also share a strong albeit slightly obnoxious lead character. I'm sure if you enjoyed one of the shows then you'd find a similar experience to be had in the other.
