The following are the events in professional sumo during 2002.

Takanohana Kōji is a Japanese former professional sumo wrestler and coach. He was the 65th man in history to reach sumo's highest rank of yokozuna, and he won 22 tournament championships between 1992 and 2001, the sixth highest total ever. The son of a popular ōzeki ranked wrestler from the 1970s, Takanohana's rise through the ranks alongside his elder brother Wakanohana and his rivalry with the foreign born yokozuna Akebono saw interest in sumo and attendance at tournaments soar during the early 1990s.
