Battojutsu is a sword-
based Japanese martial art. Generally, schools which style themselves "battojutsu ryu" emphasize the perfection of Tameshigiri cutting technique, as opposed to iaido ryu which tend to focus on drawing/sheathing, or kenjutsu ryu which stress dueling ability. "Battojutsu" or "iaijutsu" can also refer to the concept of drawing and striking in a
single motion. Batto/iaijutsu techniques often involve drawing the saya (scabbard) back and the sword forward, allowing the wielder to begin and complete the
cut faster than would otherwise be possible, generally half to three quarters of a second. Historically, battojutsu was developed around the
mid-15th century, around the advent of the uchigatana (a
type of Japanese sword). The saki-zori curvature (more curved near the tip, as opposed to koshi-zori, curved near the hilt) of uchigatana aided greatly in iaijutsu because it allowed the strike to begin before the
blade had completely left the sheath.
The term battojutsu was used during the Warring States Period, while the term iaijutsu was developed slightly later in the period as evidenced by its more philosophical
name. Since martial styles generally did not have intercourse because they were enemies (among other reasons, including geographic isolation), what
one style (
ryu) might call iaijutsu is what another style with similar movements would call battojutsu. The term iaido was not used until the end of the beginning of the 20th century, when it was first coined by Nakayama Hakudo, and therefore should not be
confused with battojutsu. Battodo is another similar word and simply means the "way" of drawing the
sword, while Battojutsu the "art" of drawing the sword.
