Sanyaku: The Three Titled Ranks
Most of the top division is numbered. One rank above it cannot be lost at all. In between sits a narrow band of three ranks that have names — and reaching it is what most careers are actually aiming at.
三役 (sanyaku) means, literally, "three roles". It is the collective name for three ranks inside makuuchi, the top division:
大関(ozeki) — the highest of the three関脇(sekiwake) — the second小結(komusubi) — the third
Where they sit
Above sanyaku is yokozuna, which cannot be demoted. Below it is 前頭 (maegashira) — everyone else in the top division, identified by a number rather than a name.
Why the names matter
That difference between a name and a number is the whole point.
A maegashira is maegashira 4 or maegashira 11. The number moves up and down every tournament according to results, and it carries no title with it.
A sekiwake is a sekiwake. There is no number attached, and the rank is a thing a wrestler can say he reached — permanently, in the record, whatever happens afterwards.
Yokozuna is out of reach for almost everyone, and ozeki takes 33 wins across three consecutive tournaments. Sekiwake and komusubi are the ranks a strong career can genuinely arrive at — which is why "he reached sanyaku" is the sentence that so often sums a wrestler up.
Two of them behave differently
The three are not equivalent, and the difference is the subject of the article on kadoban.
Sekiwake and komusubi follow the ordinary rule: a losing record drops you, that tournament, with no cushion. Wrestlers move in and out of these two ranks constantly.
Ozeki does not. A losing record there produces 角番 (kadoban) — a tournament of grace before any demotion happens. It is the only rank in sumo with that.
The trap for new viewers
Because sanyaku is a collective noun, it is not a rank in itself. Nobody is "promoted to sanyaku" as such — a wrestler is promoted to komusubi, or to sekiwake, and by doing so he is in sanyaku. Treat it as a bracket, not a step.
How many there are
These ranks are not open-ended. Unlike maegashira, which simply runs down as far as it needs to, the number of men at each sanyaku rank is small — and, as with everything on the banzuke, they exist on both the east and the west side.
That scarcity is what makes them worth holding. A place in sanyaku is not only a good position; it is one that somebody else has to vacate.
What to watch for
On the current banzuke, find the boundary between the named ranks and the numbers.
Then watch the bouts of the men at komusubi — the lowest of the three. They face the strongest opposition in the sport every day, and they hold the rank with no cushion under them. Staying there is hard.
The one of the three that behaves differently, and what it takes to get there.
