I just watch these half an hour recaps that NHK puts out everyday during the big tourneys (so 6 a year?).
Everyday like clockwork for 15 days i get to see the 21 matches of the day without any of the heheheheh fat, and with the commentary of somebody that knows the audience for those vids are casual as fuck so they explain a lot.
I dont really follow news or anything about the sport but those 15 days every two months i really enjoy sumo
