石切丸
Ishikirimaru
Also known as: The Divine Sword of Ishikiri Shrine; the Blade That Cuts Illness
Description
Ishikirimaru ('Stone-Cutting Round Blade') is the sacred sword (goshinkatana) preserved at Ishikiri Kenken Jinja in Higashi-Osaka — a shrine dedicated to Nigihayahi no Mikoto, one of the most ancient and theologically complex deities in Japanese mythology, said to have descended to Yamato before the main line of divine descent associated with the imperial family. The shrine is venerated throughout the Kansai region as the 'god of tumors and illnesses,' drawing thousands of worshippers who perform the traditional hyakudo-mairi (hundred-circuit prayer) ritual seeking cures for internal diseases and cancers. The sword's name — 'the blade that cuts stone,' implying a power that can cut through anything — became associated with the power to cut through illness, making Ishikirimaru one of Japan's most actively venerated healing-associated swords. The blade itself is a tachi of the late Heian to early Kamakura period, attributed by tradition to the great Hōki smith Yasutsuna (the maker of Dōjigiri Yasutsuna, the National Treasure tachi in the Tokyo National Museum) or alternatively to the Ko-Bizen school. It is designated an Important Cultural Property. The sword gained a new generation of devotees when it appeared as a character in the popular sword-personification game Tōken Ranbu (2015), which portrayed Ishikirimaru as a gentle, nurturing figure with healing powers — a characterization closely reflecting the sword's actual religious function.
Legends & Stories
The mythology surrounding Ishikirimaru is inseparable from the remarkable deity enshrined at Ishikiri — Nigihayahi no Mikoto, one of the most theologically intriguing figures in the entire Kojiki/Nihon Shoki corpus. According to tradition, Nigihayahi descended to the Yamato plain in a 'heavenly rock boat' (ama-no-iwafune) before the main line of divine descent arrived — making him, in effect, an earlier generation of heavenly ruler than the imperial lineage. When the ancestral Emperor Jimmu advanced on Yamato in his legendary conquest, Nigihayahi sided with the native hero Nagasunehiko until persuaded otherwise, then finally submitted to Jimmu's line, integrating this parallel divine descent into the imperial framework. This 'earlier heaven-descended god' is the deity to whom Ishikirimaru belongs as a sacred sword — a talisman from before the beginning of the imperial age, from a time even older than the oldest recorded royal mythology. The sword's name adds another layer: a blade that cuts stone can cut anything, including disease, bad fortune, spiritual pollution. The hyakudo-mairi pilgrims who walk their hundred circuits today in the shadow of the Osaka hills are participants in a religious practice older than Japanese history as we know it — carrying prayers to a god who remembers a Japan before Japan, through a sword whose name promises the impossible: to cut through the hardest things that stand between a person and their healing.
