Tsurugi

Tsurugi is a Japanese term most often associated with swords. In historical and linguistic usage, tsurugi (剣) denotes a straight, double-edged blade used in ancient and classical Japan, distinguishing it from the later curved swords such as tachi and katana. The word can refer generally to a sword, but in technical contexts it describes a straight, double-edged weapon that was common in early periods before the widespread adoption of curved blades. The form and length of tsurugi blades varied over time and region, and they are frequently identified in literature, inscriptions, and archaeological finds as one of Japan’s earlier sword types.

In Japanese mythology and imperial lore, the term tsurugi appears in the famous Kusanagi no Tsurugi, or Grass-Cutting Sword, one of the Three Imperial Regalia. According to legend, Susanoo found the blade inside the tail of an eight-headed dragon, Yamata no Orochi, and it was later presented to the Imperial Family. The sword serves as a potent symbol of authority and divine favor in Shinto and Japanese cultural narratives, and it is often referenced in art, literature, and popular culture.

Mount Tsurugi, or Tsurugi-dake, is another notable use of the name. This prominent peak in the Japanese Alps sits on the border of Toyama and Ishikawa Prefectures and approaches 3,000 meters in elevation. It is a well-known destination for climbers and hikers, offering challenging routes and alpine scenery, and it contributes to the name’s enduring presence in geography and tourism.

Beyond these, tsurugi can appear in various place names, brand names, and fictional works, reflecting its enduring association with swords and strength.
