Swordsmith of Kyoto (Yamashiro) · Heian period

Sanjō Munechika (三条宗近)

The swordsmith of Kyoto whom tradition places at the end of the 10th century: maker of the Mikazuki Munechika, one of the five swords under heaven, and hero of the legend of the fox of Inari. The documented and the legendary, his style, his works and his sources

Munechika lived, according to tradition, in the Sanjō quarter of Kyoto, in the time of Emperor Ichijō, around the Eien era (987–989), and was called Sanjō Kokaji. No blade of that time bears a date, and his life is told almost as a legend; but his tachi Mikazuki Munechika, a National Treasure at the Tokyo National Museum, is one of the 天下五剣 (tenka goken), “the five swords under heaven”.
