The Naginata is a Japanese melee weapon with a long handle (about 2 m) with an oval cross section and a curved one-sided blade (about 30 cm), with which the ancient japanese samurai fought.
Over time, a lighter version of the weapon (1.2 - 1.5 m), used in training and has shown better characteristics in combat, has established itself. The first records of the use of Naginata date back to the end of the 7th century. There were more than 400 schools in Japan that taught Naginatajutsu fighting techniques. This was the main weapon of the soldiers. The naginatas were also used by women to protect their homes.
The naginata shaft was made of oak, varnished and often had an oval cross-section, which made it easier to determine the direction of the blade during rapid rotations and interceptions. The blade could be separated from the shaft by a round guard of tsuba. The blades, with the exception of those made for noble customers, were generally inferior in quality to the tips of the spearheads. The shapes of the blades also differed: in some they resembled sword blades, in others they widened towards the end. Forged katana blades were sometimes used as naginata tips.

Kanabo is a samurai weapon of feudal Japan, a type of tetsubo in the form of a metal club with a round handle, which has a thickening with a ring at the end, and, often, supplemented by small unsharpened spikes.
Kanabo, like most weapons of the same type, was constructed from heavy wood or iron, with metal spikes or projections at one end. Its shape was the most varied: it could resemble a baseball bat, tapering from end to handle, or be completely straight from start to finish.
The size of the kanabo ranged from small sticks held with one hand to huge two-handed maces, the size of a person's height (up to 2 meters in length). It was primarily used to break the enemy's armor and cripple the limbs of his war horse. The art of wielding this bulky weapon was called kanabojutsu and consisted of training balance and strength while using the baton.

Chigiriki is a Japanese type of mace used by the ninjas. It consists of about 60 cm wooden handle and 60 - 70 cm metal chain to it, with a ball with a spike at the end of the chain. There are chains that are simply fixed to the top of the rod, and those that are placed in a cavity inside the rod and are called swinging rods. There are uses such as hitting the opponent with a weight or winding to seal the movement. Most techniques for using chigiriki are included in chigiriki-jutsu practices, which is part of the training in araki-ryu koryu - an ancient martial art, founded in early 1570 by Araki Mujinsai Minamoto.

Kodachi is a Japanese sword shorter than Daito (long sword) and slightly longer than tanto. Its blade is 40 to 65 cm long. Its size allowed the samurai to pull it out very quickly. It was used where movements were restricted, or in a body-to-body attack. Preferred weapon by the samurai, who relied mainly on their speed. Very convenient for protection, therefore called "the sword that is a shield".
During the Edo Period, the Tokugawa Shogunate was also allowed to be worn by non-samurai, usually merchants.
Kodachi, unlike Wakizashi, has a fixed length, also the curve of the blade is larger and the handle is longer.

Tanto is a samurai dagger, which was designed and used primarily as a stabbing weapon but also for finishing off opponents, cutting off heads, etc. and never as a knife. The edge can be used for slashing as well. Sometimes tanto was worn in daishho as a second sword. Tantos were used mostly by samurai, but they were also worn by doctors and traders as a weapon of self-defense. High society women sometimes also wore small tantos (called kaiken) hidden in an obi (kimono belt) for self-defense or suicide. A dummy tanto with a wooden is used for training in such martial arts as aikido, judo and karate. According to modern rules in Japan, tanto is recognized as a national cultural treasure - one of the variants of the Japanese sword.
