What size blade does an Odachi have?

The blade length of an Odachi typically ranges from 90 cm to 150 cm, with some specially made Odachi exceeding 150 cm. Due to its massive size, the Odachi was primarily used on the battlefield against cavalry and became one of the most formidable weapons among Japanese swords.

The Odachi, also known as Nodachi or 'Great Sword,' is a traditional Japanese weapon known for its remarkable length and battlefield impact. Compared to the more commonly known Katana, the Odachi holds a significant position in both functionality and historical use due to its unique dimensions.

1. What is an Odachi?

The primary feature of an Odachi is its extraordinary length. Typically, the blade of an Odachi exceeds 3 shaku (approximately 90 cm), with many examples reaching up to 5 shaku (around 150 cm) or even longer. This extended length means that the Odachi requires specialized techniques for use and carrying, often involving multiple people to effectively draw the sword.

2. Typical Odachi Dimensions

• Blade Length: The blade length of an Odachi usually falls between 90 cm and 150 cm. However, some historical Odachi far exceed this range, making them among the longest swords in Japanese history.
• Handle Length: To balance the long blade, the handle (known as "tsuka") of an Odachi is also longer than that of a typical sword, usually between 30 cm and 40 cm. This extended handle allows the wielder better control over the sword's swing.
• Overall Length: Including the scabbard, the total length of an Odachi can easily exceed 2 meters, making it a formidable presence on the battlefield and requiring specialized training for effective use.

3. Carrying and Using an Odachi

Due to its massive size, the Odachi is not carried like a typical Katana. Instead, it is carried in several specific ways:

• Back Carrying: Some samurai would carry the Odachi on their back, though this made drawing the sword during combat nearly impossible.
• Carried by Attendants: The Odachi was often carried by a samurai's attendant, who would hand it to the samurai when needed.
• Ceremonial Use: In many cases, the Odachi served as a ceremonial weapon, symbolizing the power and status of its owner rather than being used in actual combat.

4. Historical Background of the Odachi

The Odachi was not as commonly used as other Japanese swords, mainly due to its size and the specialized skills required for its use. It was typically employed in anti-cavalry tactics, designed to strike down mounted soldiers. During the Sengoku period, the Odachi also became a symbol of a samurai's courage and strength, with many swords being offered to shrines as tributes.

5. The Modern Odachi

In modern times, the Odachi is more often viewed as a collectible or display piece rather than a combat weapon. Its massive size and the skill required to forge such a sword make it a valuable asset for kendo enthusiasts and collectors of Japanese swords.

Conclusion

The Odachi is a unique and powerful weapon in the history of Japanese swords. Its remarkable size not only gave it tremendous battlefield presence but also secured its special place in history and culture. Understanding the dimensions and historical background of the Odachi helps to deepen the appreciation of this legendary weapon and its role in the traditions of the Japanese samurai. Whether for research, collection, or practice, the Odachi exemplifies the craftsmanship and warrior spirit of ancient Japan.
