In Kendo, We use a bamboo blade, called Sinai.
There are 4 areas on the body that give you points. These areas are the head, neck, wrist, and rib.
In a Kendo match, there are 3 referees watching the match. A referee raises a flag to signal that they think a point has been scored. Sometimes, only one referee raises a flag, the other two must agree or disagree with the referee.
If the majority agree, the point is scored. If the majority disagree, the point dose not count.
Kendo is influenced by Japanese Samurai culture. When a Samurai would strike his opponent, he would need to make sure his opponent was dead or surrender.
If not his opponent could strike back, the Samurai had to be caution. The same is ture for Kendo.
We may think we scored a point but must be prepared to continue fighting.
The caution is what we call Zansin.
