The Seven-Branched Sword: The Mystical Ceremonial Sword of Japan

The Isonokami Shrine is a Shinto shrine believed to have been built in 4 AD. Located in in the foothills of Tenri in Nara prefecture, Japan, this shrine is culturally significant for it houses several national treasures. These treasures include a legendary sword that is one of the Imperial Regalia of Japan, mirrors, and jewels. Among these priceless treasures is a curious sword known as the Nanatsusaya no Tachi, or ‘Seven-Branched Sword’.

The Seven-Branched Sword is so called because of the three branch-like protrusions extending on each side of the sword’s main body. Together with the tip of the central blade, they make up seven ‘branches’. This sword measures at 74.9 cm (2.5 feet) in length, and is made of iron. As the ‘branches’ appear to be quite delicate, and their functionality in melee combat doubtful, it is unlikely that the Seven-Branched Sword was used as a military weapon. Instead, it probably had a ceremonial function. This may be supported by the inscription, which is inlaid with gold, on the central blade.

A translation of the inscription is as follows,
