The Bizen School is a school that originated in Bizen Province corresponding to present-day Okayama Prefecture. Bizen has been a major production area of high quality iron sand since ancient times. The Ko-bizen school in the mid Heian period was the originator. The Bizen school consisted of schools such as Ko-bizen, Fukuoka-ichimonji, Osafune, and Hatakeda. According to a sword book written in the Kamakura period, out of 12 best swordsmiths in Japan who were convened by the Retired Emperor Go-Toba, 10 were from the Bizen school. Great swordsmiths were born one after another in the Osafune school which started in the Kamakura period, and it developed to the largest school in the history of Japanese swords. Kanemitsu and Nagayoshi of the Osafune school were apprentices to Masamune of the Sōshū school, the greatest swordsmith in Japan. While they forged high-quality swords by order, at the same time, from the Muromachi period, when wars became large-scale, they mass-produced low-quality swords for drafted farmers and for export. The Bizen school had enjoyed the highest prosperity for a long time, but declined rapidly due to a great flood occurred in the late 16th century during the Sengoku period. Their swords are often characterized by curved from the base, irregular fingerprint-like patterns on the surface of the blade, while the hamon has a flashy pattern like a series of cloves, and there is little grain but a color gradient at the boundary of the hamon. It is often evaluated as a sword with a showy and gorgeous impression.
