Japanese Weapons – The Ultimate Power Of Japanese Warriors!

1. Samurai Swords And Blades

1.1. Katana

The most popular ancient Japanese weapon is no doubt the Katana sword. It is a single-edged sword that represents the power and spirit of the Samurai. (“Samurai” refers to powerful warriors in feudal Japan. They have the highest ranking social caste of the Edo Period). In the past, only the Samurai class is allowed to use Katana. It is a unique and ultimate symbol of the Samurai tradition.

Katana is quite long but has a curved, slender, single-edged blade that allows the fighter to pull the sword out of its sheath and slash in just a blink of an eye. The blade’s length is roughly between 70 – 73 cm (over 2 shaku in Japanese measurement). Compared with the Western long swords, the Katana is lighter, shorter and has the advantage of its durability, sharpness and superiority in speed. However, while being amazingly sharp, it broke frequently.

1.2. Tanto

Next is Tanto. Similar to Katana, Tanto has been around for more than a thousand years. There are many things that a Samurai always carries with him and the Tanto sword is an inseparable object representing the martial spirit and pride of the warrior. It is a compact yet very dangerous weapon of Japanese ancient warriors. The tanto knife has a high point with a flat blade, leading to an extremely strong point with the length is about 15 – 30 cm. It is frequently used in close combat with enemies or during a ritual suicide (Seppuku).  Since the main purpose of this ritual is to protect the honor of the samurai, those who do not belong to the samurai class will never perform or be ordered to perform this ritual.

1.3. Wakizashi

Wakizashi is also one of the most powerful ancient japanese weapons that represent the Samurai. It appeared in the 15th century. It has a blade that is between 30 and 60 cm long. For one which has the same length as Katana, it is called O-wakizashi. For one with length equal to Tanto (short blade), it is called KO-wakizashi.

Samurai normally wear the sword on the left hip. When Wakizashi and Katana are together, the Japanese call them “Daisho”. Not only is a supporting weapon for the Katana, Wakizashi is a special equipment to decapitate enemies. Not only that, similar to Tanto, Wakizashi is also associated with a famous ritual of the Samurai, Seppuku.

The Samurai showed their respect to Wakizashi by never leaving the sword behind. When Samurai enter someone’s house or the palace, they leave the Katana at the door and only bring Wakizashi in.

1.4. Odachi

Odachi or ōdachi, nodachi is a traditional Japanese sword style, used by samurai during feudal times. The blades are usually about 100 cm long, with some notable blades that can reach up to 2 m long. Ancient Japanese people were generally modest in height, so a sword that is longer than 100 cm is not really suitable in melee combat. In fact,  Odachi is frequently used by cavalry.

1.5. Tachi

The tachi sword is a traditionally crafted Japanese sword dating back to the Kotō period (900-1596), and is a design that preceded the katana.

The structure of Tachi and Katana are quite similar. The biggest difference is that Tachi is longer and heavier than the Katana. And Samurai wear the katana with its cutting-edge facing down while they wear the katana with its blade facing up. Another difference is that Tachi has 2 ears that resemble a handle called Ashi. The name is also a point to distinguish, many documents call Tachi Ko-Dachi (because Tachi is shorter than No-Dachi).

You can see clearly the differences among these swords in the pictures below:

2. Kusarigama

Another impressive traditional Japanese weapon is Kusarigama. The kusarigama (Japanese: 鎖鎌, lit. “chain-sickle”) consists of a kama (the Japanese equivalent of a sickle) on a kusari-fundo – a type of metal chain (kusari) with a heavy iron weight (fundo). It first appeared in the Muromachi period.

In comparison with swords, Kusarigama is a weaker weapon.  It has a fatal weakness: Kusarigama requires time to “warm-up”. To be ready to strike, Kusarigama had to reach the maximum rotation speed of the chain to make the opponent wary. After each hit, Kusarigama will need time to “restart” before giving the next attack. This is the factor that makes the Kusarigama unable to become an all-round weapon. Regarding the ability to fight on the battlefield, the Kusarigama may not be the perfect weapon. But in normal combat, Kusarigama is quite effective. It has an important role in the history of Japanese martial arts.

One notable thing about Yumi is that the bow is exceptionally tall in comparison with bows from other countries. Its length is about two meters and typically surpasses the height of the archer.

Japanese people insert the hilt into the wooden body (Nagaye) through a hole. Then attach them tightly to the protruding branches.
