The final winner of the match Akibono (from Hawaii) pushes his challenger out 
  of the ring. This was a fun activity to watch as a spectator and I would do 
  it again. Actually, far more interesting then most spectator sports.
       Sumo wrestling has its roots in Shinto festivals. 
  The matches were intended to entertain the kami (deities) and gain favor for 
  their protection and benevolence.
