I'm not sure what you have heard, but during the Grand Sumo tournaments, matches run almost all day. The younger, trainee fighters are early and the 2 upper divisions are in the afternoon and evening. The top, championship division runs from 4:00 PM until around 6:00. You are correct that each individual match usually lasts only seconds but there are many matches each day. You buy a ticket and stay as long as you want. Many folks bring, or buy on-site, boxed meals and beverages and make a party of it.
It doesn't really matter in your case as the current tournament in Osaka will be ending by the time you arrive and the next one in Tokyo isn't until May.
