Osafune Morimistu Tachi

Osafune Morimistu was a sword maker who worked in Osafune, Bizen Province (present-day Setouchi, Okayama Prefecture) during the early Muromachi period. Celebrated alongside his colleague Yasuminsu as one of the 'Masters of the Ōei era,' he is regarded as an exemplary craftsman of Bizen blades. He produced many works especially around the Ōei era (1394–1428) and is highly valued as a master who embodied the aesthetic of the transitional period from the bold, robust style of the Northern and Southern Courts period to the refined elegance of the Muromachi era. This tachi has a blade length of approximately 70 cm and is characterized by its dignified form with a slight waist curve. The hamon displays an elegant composition of gunome midare with clove-like toji elements. The jigane exhibits a bright and refined finish using high-quality iron sand in the Bizen tradition, with evenly distributed ji-nie throughout. Morimistu's blades represent a masterful fusion of the grandeur of the Northern and Southern Courts period with the refinement of the Muromachi era, and his works continue to be highly valued by sword collectors today. His works are held in numerous important museums throughout Japan, including the Okayama Prefectural Museum, bearing testament to the prominence of Bizen blade-making.
