Is sumo fixed, or scripted like pro wrestling?
Sumo is not scripted. Outcomes are not written in advance the way they are in pro wrestling. The sport does have one confirmed real scandal - in 2011, leaked texts proved several wrestlers had fixed specific bouts, and the Japan Sumo Association cancelled that March's tournament entirely, the first cancellation since 1946.
What you are seeing
- In 2011, investigators found cell phone messages between wrestlers arranging the outcomes of specific bouts.
- The Japan Sumo Association cancelled the March 2011 tournament in Osaka outright, the first grand tournament cancellation since 1946, when the main Tokyo stadium was still being rebuilt after wartime damage.
- 23 wrestlers were ultimately found responsible and expelled from the sport.
What to watch next
- Watch a close bout at the edge of the dohyo - the effort and balance involved are hard to fake convincingly for 15 straight days.
- Notice that upsets happen constantly; lower-ranked wrestlers beat favorites often enough that a fixed outcome would be a strange way to keep an audience.
- If a decision looks controversial, that is usually mono-ii (a judges' conference), not evidence of anything arranged.
A common first-timer mistake
Assuming one scandal from 15 years ago means every close or surprising result is suspicious. It does not; it means the sport has already been through this and expelled the people responsible.
