Watch the final moments
A sumo exchange can end quickly, which makes it tempting to describe everything as a push. Instead, watch where the wrestlers are, whether they are in close contact and what happens at the ring boundary. The purpose of this first viewing is to notice the sequence, not to make an instant expert ruling. A demonstration can help because the instructor may explain the same action at a pace suitable for the group.
Connect the result with its technique
The Japan Sumo Association identifies winning techniques, known as kimarite, in an illustrated catalogue. For example, oshidashi involves pushing an opponent outside the ring, while yorikiri involves advancing with close body contact to force the opponent out. Both can end at the boundary, but they describe different actions. Listening for the technique name gives you something specific to revisit after the bout, rather than relying only on the impression of size or speed.
Bring your questions to the ring
During private training, you might ask what distinguishes two finishes or how an instructor decides which example to demonstrate. Do not assume that a visitor session reproduces every action seen in professional competition. The appropriate activities are determined within the session, with instruction and interpretation as arranged for the booking. Afterward, choose one technique to look up in the official catalogue. Learning to recognise a small number of clear examples is a practical starting point for enjoying future sumo viewing.
