On a serious note.
IF you have a smart TV - who doesn't now? - The NHK Japan app is free and contains a ton of free programs.
Main thing, Yo, they host all the sumo tournaments. I am currently watching the January Tournament. It's awesome. It ain't just fat dudes slamming bellies.
They have a name for every "move" for a win. It's really fun to learn the names of a couple easy ones and then try to call each win by name. Oshidashi is an easy one. Frontal push out!
Legit, sumo is pretty fun to watch.
