This blade exhibits the characteristic workmanship of the Yamato Taima School, including long nij\u016bba with ko-ashi appearing within the temper line and an almost yakitsume boshi.

Historical Background:
\nThe J\u014dji era (1362\u20131368) of the Northern Court during the Nanbokuch\u014d period was a time of significant political upheaval within the Muromachi Shogunate. Internal conflicts, including the aftermath of the Kann\u014d Disturbance, reshaped the balance of power, eventually leading to the succession of Ashikaga Yoshimitsu as shogun. It was an era in which the military government underwent major political changes, and swords forged during this period are highly valued for their historical significance as well as their outstanding craftsmanship.<\/p>\n
