Is a term used for a military kit worn on the left side, attached to the belt. It comes in various shapes and lengths.
The original Tachi kits were slim and straight, based on the Chinese style. They were used throughout the entire period of sword use, including for ceremonial purposes and at the imperial court.
The origins of the typical Japanese sword date back to the 8th century. It is a single-edged, slightly curved blade of various lengths and with slight variations, still being used today. Their tachi sets were produced in many variations, from wooden lacquered and all-metal to leather-wrapped. All types were worn by samurai attached to their belts on horseback.
In the 14th century, extremely large and long swords and sets were created, which were used against infantry and horses (O DACHI). Later, they served as votive objects and offerings for temples.
Overall, tachi sets were used throughout the entire period of sword use until around the 19th century.
