Kendo is a modern Japanese martial art, which descended from swordsmanship, known as kenjutsu, and uses bamboo swords. In Ninja Kendo, you will face Sensei and try to block as much of his attack as possible. He may not look impressive, but dont be fooled he is a master of martial arts, and can be as quick as he wants to be. Game continues as long as you successfully keep blocking. How long can you endur senseiâs training?
