If you are interested in seeing the top-level guys, they enter just before 4:00 pm for the colorful dohyo iri and fight until 6:00 pm. From 2:00 pm to 4:00 pm the next division down will fight. Called juryo, they are equivalent to AAA minor leagues in American baseball. In the morning, the even lower divisions fight. They are often rookies who are starting out.
The highest ranked rikishi, the ozeki (champions) and yokozuna (grand champions) are always the last to fight, roughly from 5:20-6:00 pm. There are currently 4 ozeki and 3 yokozunas, although one of the ozekis is in danger of demotion unless he has a winning tournament next month. The yokozunas generally fight in the last 3 matches of the evening unless, of course, they are facing one another. In the second week, the top guys will all start fighting each other, which makes for some exciting matches late in the day.
As mentioned above, the day for the top division starts with the dohyo iri and the yokozuna's appearance and ends after the last match with the short "bow twirling" demonstration. These are rituals that always take place and many in the audience watch and enjoy them almost as much as the fights.
The "A" stadium seats are bleacher seating in the top few rows of the long sides of the stadium. They are pretty high up and quite a ways from the ring. Many who sit there to save money often bring opera glasses or binoculars.
