Where are actually all these videos from? They look like some kind of yearly contest or festival? Is there something like a shamisen festival in Japan?
Hey oonabe, I will be obliged to answer you’re question. These videos are from a shamisen tournament called: “The National Tsugaru Shamisen Championship”. It is a tournament for Tsugaru shamisen known from all over Japan. It happens only one a year in early Spring in Hirosaki, Japan, and it is streamed on Youtube. The streams verify in length, but the usual length is about 7 to 9 hours. Here is a link to a guy I know that streams the tournament every year. (第２２回 津軽三味線コンクール全国大会 - YouTube) You may watch this anytime you want because it’s so long. I really want to play at this event sometime in the future, so be on the lookout for me! 
(By the way, if you know Norm, the guy that films Ki&Ki videos, he is in this tournament. He performs at: 3hrs, 56mins. If you want to find out more about him, here are some links to his videos.) = (https://www.youtube.com/channel/UCnrVURWNd7VYjlQQ0UDpOQQ) and (https://www.youtube.com/channel/UCF9s4ffoxjk8-AgzCEe8QqQ) Enjoy!
Wow, very nice information, thanks a lot for sharing. I wished I could find similar channels that stream Japanese contests and similar live on YT, but that would be a theme for a different thread.
If you manage to get to the tournament let me know, I’d be glad to watch and of course if that happens you’ll have to tell me which of the many players you are. I’ll be there cheering digitally 
thanks a lot, arigatou gozaimashita
Nevermind the shamisen, Kitano can tap dance!?

Mike Penny did this medley of Jesus Christ Superstar tunes around Easter. I got a real kick out of it since my mother listened to this a lot when I was a kid
I don’t think this one has been posted before. Even if it has, it’s worth watching again.
