One of the earliest Japanese swords is called the tachi.
The Tachi Japanese Sword is also the most common of all swords in Japanese History.
The tachi sword was worn hanging from the waist using cords.
The Tachi sword came about as a need developed for a sword that was useable for horseback fighting.
Previously sword fighting had been done on foot.
During the era of the Japanese Tachi Sword it started to became common practise for the sword makers to sign their name on the blade.
Later, when the Mongols invaded, it was shown there were some weaknesses in the Tachi sword which eventually led to the development of the Katana sword style.
As time went on, the Tachi sword became more ceremonial in nature.
