  • In the Muromachi period, the OSAFUNE SCHOOL(長船派) prevailed in the Bizen province and almost all schools in the region were practically absorbed by the school so that there were no distinctive differences in style among the schools of that period. For that reason, the Bizen swords made in the Muromachi period are often classified by the era instead of the school.
