Kiku-ichimonji
Kiku-ichimonji (菊一文字, chrysanthemum + ichimonji (straight-line mark, “Ichimonji” refers to a stylistic lineage/marking convention, not a literal phrase one would naturally translate into English).) ('Ichimonji-style blade with chrysanthemum crest'), often romanized with a somewhat misplaced hyphen as Kikuichi-monji, is a collective name given to the katana (a type of Japanese sword) made by the thirteen swordsmiths who were in attendance to the Emperor Go-Toba in 1208. Each swordsmith was in attendance to the emperor for a month of the Japanese calendar.
