The sword was introduced to Japan from the Continent around the 2nd century BC. They say that the sword was originally a ritual colored object which symbolized the authority of its owner rather than a weapon. At that time, the catapult and bow were used for hunting or tribal warfare. However, the sword gradually became used for fighting through continuous group conflicts in the course of national unification. By the 7-8th century, the sword was being forged domestically.

After the 9th century, as the Bushi class was established, the prototype of the Nihon-to (the Japanese sword) was formed. Various sword fighting techniques as well as forging techniques had been developed. However, on the battlefield, swords that were longer than 6 feet and spears were the main weapons until the 14th century.

After the Shogunate government was abolished in 1867, modern Japan was formed and the Bushi class became extinct; the right to bear a sword was also banned. As a result, Kenjutsu temporarily declined in popularity. However, on suppressing the rebellion that broke out in 1877, the achievement of police officers who mastered Kenjutsu was highly respected. At the same time, there was a need to enhance the wealth and military strength on a national scale in order to compete with the Great Powers of the world.

Under such circumstances, the promotion of Kenjutsu was reexamined. In 1879, the Metropolitan Police Bureau of Tokyo began giving Kenjutsu courses for its officers. In 1895, Dai Nippon Butoku Kai was formed as an organization devoted to all martial arts. However, the popularization of Kenjutsu demanded a universal form, one that would include and integrate all existing schools of Kenjutsu. In 1912, after a long deliberation among masters of major Kenjutsu schools, a new system of Kenjutsu that transcended existing schools was established. This is the birth of Kendo. Since then, Kendo has officially become part of the physical education program initially at the secondary school level, and then in primary schools. As a result, Kendo flourished, and many tournaments were held all over Japan.

Now, since the establishment of the International Kendo Federation in 1970, Kendo has become popular even outside of Japan. Countries such as Canada, Brazil, England, France, Germany, Korea, the United States, and many others have begun practice Kendo. There are many more federations exist internationally, as people in other countries take increasing interest in Kendo. Modern Kendo is the result of many changes, from a purely fighting art, to an all encompassing martial art.

Besides such training, the practice of etiquette through Kendo is demanded as well, since the goal of Kendo is to develop one's character, i.e. self-confidence, courtesy, and respect for others. This was of utmost importance for all Samurai.

Kendo is demanding both physically and mentally. However, many people, regardless of age or sex, are attracted to Kendo and still carry on the tradition that had been handed down from Samurai culture. Although the path is not an easy one, practicing Kendo will surely enable you to attain the willpower to overcome adversity.
