Do you know KENDO? When i was 8 years old, I have been practiced Kendo for about 16years. I'm Kendo 3 Dan. Kendo is a Japanese traditional martial arts (sports?). In this game which is an one to one battle, we fight with bamboo blades. We hit a point(head, throat, wrist or abdomen ) with the sword. The player who take 2 points, he gain a victory. "Dan" is a garading system which has 1~8 levels. Dan proves KENDO players' technical skill including mental factor. The higher skill he have, the higher Dan he is given. ↓introduce YouTube video https://youtu.be/8DslhPy-CiQ Hi! I'm Satoru. Nice to meet you. I'd like to make friends with you!
