Ichigo Hitofuri

Originally named Okatana Yoshimitsu Ichigo Hitofuri once belonged to the Asakura clan of Echizen province until the family was destroyed in 1573 during the course of Oda Nobunagas seizure of power which transferred its ownership to the Mri clan. On the 18th of September 1590 Toyotomi Hideyoshi visited the Mri estate and the sword was given to him. Toyotomi Hideyoshi wanted to wear Ichigo Hitofuri by all means and ordered the blade to be shortened to match his rather short height. Ichigo Hitofuri was damaged in the summer of 1615 during the Siege of Osaka at Osaka Castle and then retempered by Yasutsugu under the order of Tokugawa Ieyasu. However Ieyasu didnt get the chance to use this sword because he was advised by the Priest Tenkai to avoid sending Hideyoshis swords including Ichigo Hitofuri to Edo. Ichigo Hitofuri remained in possession of the Owari branch of the Tokugawa until Tokugawa Mochinaga presented the sword to Emperor Koumei on January 29th 1863 and it has been an Imperial treasure since that time alongside Tsurumaru Kuninaga Uguisumaru and Hirano Toushirou.
