Yuuhakkan Dojo, which means "cross swords among friends," is a group of friends who meet regularly to practice Kendo. With the opening up this community to new members, it became necessary to create an image to represent them. The artistic design was entirely based on Japanese heraldry, through the use of pre-established concepts (friends + cross swords) in a unique way called Kamon (crest Japanese). The helmets Kendo in continuous circle represents the never-ending friendship through martial art. In the center, in a very delicate way, there is a flower formed from the touch of the tips of bamboo swords used in training. However, the logo has several flowers of different ways. They also represent the monentos only experienced by the group.
