Kendo is a Japanese martial art, which uses bamboo swords to strike the opponent. It would be unsightly if you swing the sword wildly without knowing any sword skills.
When you have respect and a caring heart, you will hit the heart of your opponent even if you don't attack him/her recklessly.
In SYUBUKAN, people do everything with gratitude. Emphasis is placed on etiquette to encourage respect for the opponent, and nurture people with a humane character. Meanwhile, the trainees work hard on the training of the techniques every day.
