A few months ago I couldn't sleep, so I turned on the TV and flipped through the regular old channels for the first time in probably about 15 years. There was a sumo tournament on NHK (Japanese public broadcaster) and I was immediately hooked. I've been following each tournament since then. For anyone who's curious about it, matches are very easy to understand if you just want to watch the sport, but if you decide to starting looking up more information about the history behind these events, there is so much to read.
