- Japanese: 正宗 (Masamune)
Masamune was the apprentice or student of Shintôgo Kunimitsu, and is said to have been adopted by Sôshû Yukimitsu, another of Kunimitsu's students. Yukimitsu is also considered the second-generation master of the Sôshû school of swordsmiths.
Early on, Masamune mimicked the distinctive tempering pattern of Kunimitsu's blades, a style known as Sôshûmono after Sagami province (Sôshû) where they were made, and perfected or completed that style. After developing his own style, he passed it on to his son Sadamune, who went on to become a significant swordsmith in his own right.
Several of Masamune's blades are today considered National Treasures; these have names such as "Kanze Masamune" and "Hôchô Masamune." Most of his swords, however, bear no inscription. Only four tantô by Masamune which feature markings are extant. These are known as "Fudô Masamune," "Daikoku Masamune," "Kyôgoku Masamune," and "Honsô Masamune."
Though today often referred to as the greatest master of all Japanese master swordsmiths, it was not until the Azuchi-Momoyama period (late 16th century), when Toyotomi Hideyoshi made a habit of giving Masamune blades as formal gifts, that he came to be regarded as such.
Masamune is buried at Hongaku-ji, a temple in Kamakura. In addition to a rounded gravestone over the presumed site of his actual grave, a monument in his honor stands near the entrance to the temple's cemetery.
