Beginning of Soshu style

After the Mongolian invasion, that is the later part of the Kamakura period, a new style of sword started to emerge.  Kamakura area became prosperous under the rule of Hojo(北条).  Many swords smiths moved to Kamakura.  They are Kunituna and his group of Yamashiro and Fukuoka Ichimonji Sukezane (福岡一文字助真), Kunimune (国宗) of Bizen.  They are the origin of Soshu school (相州).  A star sword smith, Goro-Nyudo-Masamune (五郎入道正宗) appeared during this time.
