Why did Kimura get destroyed in pro wrestling?

I know that Japanese are notorious for turning worked matches into shoot but that was one of the worst.

 

Apparently the other guy was stabbed and killed by Yakuzas after this. Kimura claimed he called those Yakuzas but people were calling bullshit on Kimura's claims.

yea, Kimura got a little too stiff & Rikid?zan shot on him. It was supposed to be a draw to set up future bouts
