This is a list of records held by wrestlers of professional sumo. Only performances in official tournaments or honbasho are included here. Since 1958 six honbasho have been held every year, giving wrestlers from the modern era more opportunities to accumulate championships and wins. Before this, tournaments were held less frequently; sometimes only once or twice per year.
This table lists wrestlers with the most championships achieved without a single loss, which is known as a zenshō-yūshō. Tournaments have been consistently fifteen days long since May 1949. Before that date there were a number of different lengths, including ten, eleven, twelve, and thirteen days. The records of Tachiyama, Tochigiyama and Tsunenohana also include some draws, holds and rest days.
+ Includes a sweep of all six tournaments in 2005. Asashōryū remains the only sumotori to have won all tournaments in a 6-tournament calendar year (post-1949). † Four of these titles were zenshō-yūshō (undefeated championships) and were part of Hakuhō's second-place streak of 63 consecutive wins. ‡ All of Futabayama's victories in this streak were zenshō-yūshō (undefeated championships) and were part of Futabayama's record setting 69 consecutive wins.
The list includes yokozuna and ōzeki (the highest rank before the yokozuna rank was introduced), but excludes so-called kanban or "guest ōzeki" (usually big men drawn from local crowds to promote a tournament who would never appear on the banzuke again) and wrestlers for which insufficient data is available.
The table for the fastest progress shows wrestlers with the fewest tournaments from their professional debut to their top division debut since the six tournaments a year system was introduced in 1958. It excludes makushita tsukedashi entrants who made their debut in the third makushita division.
^Raiden is said to have won 28 tournaments between 1790 and 1810, Tanikaze 21 between 1772 and 1793, and Kashiwado 16 between 1812 and 1822. Tachiyama won two unofficial championships and nine official, giving him a total of 11.
^the winning streaks of Tanikaze, Umegatani, and Tachiyama were interrupted by draws and rest days. The others listed were all wins only.
