This is another reason why Sumo which is an amazing martial art never really grew in popularity outside of Japan. Even now, a bunch of us enthusiasts need to watch the bashos with the help of YouTubers who can be DMCAed any moment.
Being practiced by almost exclusively Japanese probably doesn't help either; you can't root for your "home team", so to speak. No one watched darts in the Netherlands, then a Dutch candidate won the world title 25 years ago and everyone in the Netherlands was watching it.
That depends what you mean by "Japanese". Naturalized Japanese, probably, but a fair number of the wrestlers are originally from Mongolia or Eastern Europe now.
Though I don't follow it myself so don't know how interesting it is. Always wanted to try the food though.
found this recently for those interested! worth it for ads alone.
