The odachi sword and nodachi sword represent one of the most common points of confusion among Japanese weapons fans. Even though both these swords belong to the class of big swords meant to be wielded with two hands, some differences between these swords should be considered.

If you have looked into the world of large Japanese swords, you may have come across these names. While they seem synonymous at first glance, that is far from being true. There are some important differences that can come in handy if you are collecting swords. 

Find out the difference below.

What is an Odachi Sword?

An Odachi sword, which literally translates to “big sword,” is one of the longest swords that have ever been made in the history of Japan. An odachi sword would measure more than 90 centimeters in length and would even surpass 150 centimeters on certain occasions when they were used for rituals.

They could not be used in battle because they were too long to be drawn from the scabbard on a warrior’s back. They either carried an odachi sword using the help of an attendant or had to draw it using their hands.

Definition of a Nodachi Sword

The nodachi sword is similar yet distinct in terms of function. Most nodachis had blades measuring between 90 and 120 cm, making them practical for military purposes. Soldiers, particularly those on horseback, would employ the nodachi to attack enemies on the battlefield.

In contrast to the odachi, the nodachi was designed for combat. The nodachi's heaviness made it effective in battles against enemy soldiers and their horses.

Odachi Sword vs Nodachi Sword: Key Differences

Size and Blade Shape

First and foremost, it is clear that odachi swords tend to be larger and heavier. This sword is not as focused on being practical as the nodachi. Instead, the sori and blade shape will be much stronger and more visually impressive.

In contrast, the nodachi sword will focus on balance. It is a functional weapon that a trained soldier can actually swing around. Commonalities include the unique construction and materials used for these Japanese swords: layering tamahagane steel, a hamon, and polishing for a beautiful finish.

Historical Background and Significance

The odachi swords were made in large numbers during the Nanboku-cho period, which was marked by civil wars in Japan between the years 1336 and 1392. They were ordered to showcase power and dedication. Most of the blades were designed to be kept at the shrine only.

The nodachi blade's primary application has been linked to the tactics used by Japanese footmen during battles such as that at Sekigahara. Following the pacification of Japan under the Tokugawa shogunate, restrictions on sword length led to their discontinuation.

Choosing the Right Sword

Go for the odachi if you:

• Wish to own a decorative sword that makes a strong statement
• Are fascinated by the rituals and ceremonies in Japan’s past
• Want a sword that is not only dramatic in appearance but also rich in culture

Go for the nodachi if you:

• Are you looking for authenticity linked to combat situations
• Interested in knowing more about Japanese sword construction
• Will be using your replica in martial arts practice or reenactments

Conclusion

The odachi sword and nodachi sword are two very important types of big swords used during the course of Japanese history. However, their roles were vastly different. The odachi symbolizes power, status, and ritual. The nodachi symbolizes innovation on the battlefield. Either would make an excellent addition to any collection.
