I was dreading this yet I was also incredibly curious about seeing this.  At Katsura-hama, the beach at Kochi, they have dog fights.  The dogs have ranks like sumo wrestlers and they have some ornamental clothing which is similar.  During the fight I felt really bad for the dogs.  I like dogs.

They lit a roll of paper and put it between the dogs when one yelps, and they declared non-yelper the winner.  There was blood and pieces of fur on the ring floor.  I felt a bit ill.  But then I went and saw the most bizarre thing one could see after a dog fight.
