Mainstream faction in Bizen province during Kamakura period were Ichimonji and Osafune schools. Since the advent of Ichimonji sword maker NORIMUNE 則宗, the nature of Japanese sword has changed drastically. Emperor Go-Toba nominated him as one of the official sword smiths of Emperor. Emperor Go-Toba conferred smith NORIMUNE 則宗 the title of "Tenka Ichi 天下一" to take the top of the sword smiths. He or his lineages of Ichimonji-schools sometimes added the title of "ICHIMONJI 一" in addition of smith name or sometimes chiselled only the title of "ICHIMONJI 一" or occasionally add both.
