Each child who grew up in a samurai family was expected to be a warrior when he grew up, so much of his childhood was spent practicing different martial arts. A complete samurai should be skilled at least in the use of the sword ("kenjutsu"), the bow and arrow ("kyujutsu"), the spear ("sojutsu", "yarijutsu"), the halberd ("naginatajutsu") and subsequently the use of firearms (houjutsu). Similarly, they were instructed in the use of these weapons while riding a horse. They were also expected to know how to swim and dive.
