If you’re interested in watching some sumo, NHK put up English-commentated 30 minute ad-free round-up videos on YouTube for each day of each fifteen-day-long basho. They take each video down after a week or so, so you need to be watching at the time. The next basho is held in Ōsaka and starts March 8th (see https://www.japantimes.co.jp/sports/sumo/basho-schedule/).
