Okazaki Masamune, also known as Goro Nyudo Masamune (Priest Goro Masamune), is widely recognized as Japan's greatest swordmaker. As no exact dates are known for Masamune's life, he has reached an almost legendary status. It is generally agreed that he made most of his swords in the late 13th and early 14th centuries, 1288-1328. He created swords, known as tachi in Japanese and daggers called tanto, in the Soshu tradition. He is believed to have lived and worked in the Sagami Province. An award for swordmakers exists called the Masamune prize, which is awarded at the Japanese Sword Making Competition. Although not awarded every year, it is presented to a swordmaker who has created an exceptional work.
Masamune is believed to have worked in Sagami Province during the last part of the Kamakura-era (1288-1328), and it is thought that he was trained by swordmakers from Bizen and Yamashiro provinces, such as Kunitsuna and Kunimitsu.
