This is taken from the Nippon Ijin Taisho 2007 featuring Son Goku as a kind of special guest commentator. I don't how many others may have already seen this but I have posted for those who haven't. It is completely in Japanese with no subtitles.
It is like a tournament with real people portrayed as anime characters in a kind of Dragonball style. Goku doesn't really do much except sit on the kintoun and say something ever so often. The fights themselves are very short and not too engaging but I thought it might interesting just to take a look. The characters are also voiced supposedly by the seiyu of a few DBZ characters.
