Had a great day learning about the sport of Sumo. I didn't realize why they did the clapping, stamping of the feet, salting the ring, etc. but now I do. If you want to know, you'll have to wait until I get home to ask. The day was long because I wanted to be there at 10:30am when the matches started. Who would have known the matches would go until about 6:00pm. That's why the locals don't show up until then.
