Dōjigiri

Dōjigiri (童子切, "Slayer of Shuten-dōji") is a tachi-type Japanese sword that has been identified as a National Treasure of Japan.

Dōjigiri is sometimes called "the yokozuna of all Japanese swords" along with Ōkanehira (ja:大包平) because of its perfection; it is of great historical value as one of the oldest extant katana-type weapons.

[2] The present mounts of the Dojigiri are fine examples of Momoyama-period work in itomaki no tachi style, in which the typical wrapping of the hilt continues along part of the scabbard.

[3] Dōjigiri was presented to Oda Nobunaga, the leading late sixteenth century general (1534-82), by the Ashikaga family.

After the disgrace and dispossession of the Echizen Matsudaira occasioned by some irregular conduct on the part of Tadanao, the blade passed to the Tsuyama branch of the family.
