30-SECOND SUMO ANSWER

What's not allowed in sumo? The forbidden moves (kinjite)

Eight moves are banned outright, called kinjite: closed-fist punching, hair pulling, eye or solar-plexus gouging, striking both ears at once, groin grabbing, choking, kicking the chest or waist, and bending fingers back. Any of these is an automatic loss (hansoku) - they exist purely to prevent lasting injury, not to limit strategy.

What you are seeing

  • Open-handed thrusts to the chest or face (tsuppari) are completely legal - it's specifically the closed fist that's banned.
  • Wrestlers grab the mawashi constantly, anywhere around the waist and hips - just never the front pouch.
  • A wrestler whose mawashi comes fully undone also loses automatically, regardless of position in the bout.

What to watch next

  1. Watch the hands during a scramble at the edge - open palms and grips on the belt are legal, a closed fist would be an immediate foul.
  2. Kicking an opponent's leg out from under him is a real, legal technique (ashitori and similar); it's kicking the body itself that's banned.
  3. A hansoku disqualification is rare enough at the top level that most fans never see one live - the eight banned moves mostly shape what wrestlers avoid, not what referees have to call.
03

A common first-timer mistake

Assuming any hard-looking slap or shove is illegal. Sumo is genuinely rough within its rules; the banned list is narrow and specifically aimed at moves that cause lasting harm rather than moves that simply look violent.
