Kendo is a Japanese martial art where people compete using bamboo swords.
In kendo competitions, scores are not given as numbers but are decided by judges.
Judges look at whether the competitor's movements, spirit, and body are united.
A point is counted only if the strike is correct, powerful, and timed well.
Sometimes, the judges' decisions make competitors and spectators feel unfair.
Some people hope to use video replay or sensors to help judges, making scoring clearer.
But others think kendo is not just a competition; learning spirit and self-improvement are more important.
If only technology is used, the tradition and educational meaning of kendo might be lost.
Nowadays, many people discuss whether to use new technology, and some suggest improving the judges' rules first to make competitions fairer.
