Katana, Wakizashi, Yumi, Yari, Naginata, are all forms of Samurai weapons. When a child reaches the age of 13, children would have to go through a ceremony called Genpuku, which is when the child was given a wakizashi and given an adult name, which made them a samurai. a wakizashi and a Katana together were called a daisho. Normally, a Samurai's weapon of choice was a Yumi, or a compund bow and it was unchanged for centuries until the introduction of gunpowder and rifle in the 16th century. It was usually used on foot behind a tedate (手盾), a large wooden shield, but it could be used even from horseback.In the century, the yari or spear also became a popular weapon. It displaced the naginata from the battlefield as personal bravery became a less of a factor and battles became organized. After the matchlock rifle was introduced from Europe, samurai started practicing this weapon. It became the favorite weapon for sniping on the battle field as samurai were awarded for every enemy he took down himself, though commanding was an important aspect of samurai. Conscripted soldiers also used matchlock rifles but instead fired in volleys to break up enemy ranks. Toward the end of the feudal period, some samurai organized dragoons as part of their troops and some were reportedly used in the Battle of Sekigahara and later battles.Some samurai were unarmed on the battle fields except for katana. Takeda Shingen was one such samurai. This did not mean that they fought using katana. Instead, they focused on commanding and were confident that they could trust those they commanded for protection. In one of the Battle of Kawanakajima, this almost got Shingen killed. A plan went wrong and troops of Uesugi Kenshin charged into troops under Shingen's command, who were unaware that his entrapment plan had been detected. With only half of his troops and completely surprised, Shingen himself had to defend his life with a wooden stick that he used to order attacks. The rest of his soldiers barely returned in time to save Shingen and the rest of his force from being completely wiped out.
