NHK shows highlights from a Grand Sumo tournament every other month. I think it's day 9 of 15 today. In around 25 minutes they show a bunch of matches and after that they have a couple minute segment, Sumopedia that explains aspects of the sport. In the Eastern time zone it's shown at 12:30 pm and 6:30 pm. Fascinating to see big men run into each other, on one of the Sumopedia segments they recorded 13 G's with the initial hit. But for big men they show dexterity I only wish I had. And the slow motion they show after each bout is one of those things that might make you cringe but hard to stop watching. It's going to be part of the 2020 Olympics.
