P4 / Origins
Shusshin (birthplace) of the wrestlers
Sumo is Japan's national sport, but Makuuchi (the top division) has been shaped for decades by Mongolian wrestlers - Hakuho, Asashoryu, and now Hoshoryu and Onosato. Origins are listed by prefecture for Japan and by country otherwise. For every birthplace's full roster - active and historical - see the full origin directory, plus the kabu (elder-name stock) lineages wrestlers enter after retirement.
