No idea about anyone else but we have zero to do with any editing that goes on Samurai TV. They do it all in house. Someone that works for the company that runs Korakuen Hall and Sumo Hall puts together Korakuen video packages that air on Samurai.
And in case anyone just never knew or whatever, Samurai sends a camera man to 95% of our shows, I am sure it is the same for other groups to use for their nightly news.
