How to Distinguish Between Real and Fake Samurai Swords

After identifying a platform for purchasing a katana, you're ready to make your selection online or at a specialty store in Japan. At this point, you encounter a new concern: the fear of purchasing a counterfeit katana. As a sales manager for vee katana, I have a strong voice on this matter. Many of our customers had been deceived before purchasing our products, whether online or in-store, where the merchant claimed to sell an "authentic Japanese katana" but it was actually a cheap imitation. Five years ago, when I first became fascinated with katana, I also bought a counterfeit one. I hope that by sharing my experience, I can help you avoid the traps I once fell into, especially when buying online.

Personal Story
First Encounter with Katana

My fascination with katana began five years ago by chance when I was casually browsing online and stumbled upon a store claiming to sell "real japanese katana swords for sale." At the time, I knew very little about the history and craftsmanship of katana and was completely drawn in by the glossy images and descriptions. Without doing enough research, I hastily placed an order. The katana I received weeks later was far below expectations, of poor quality, and clearly a cheap imitation. This failed purchase experience led me to delve deeply into how to distinguish between real and fake katana.

Facing Challenges

As the sales manager for the vee katana brand, I had the opportunity to handle various types of katana, which allowed me to learn many techniques for distinguishing between real and fake ones. I purchased katana from different platforms, including online stores and specialty stores in Japan, and after each purchase, I would compare and analyze them, gradually developing my own set of identification methods. Below, I will share some detailed methods and tips that I have learned over many years of collecting and studying katana.

How to Identify Real and Fake Katana
Observing Craftsmanship
  • Forging Marks:True Japanese katana are made using traditional forging techniques, leaving unique textures (such as "waves") on the blade. These textures are difficult for imitations to replicate.
  • Signatures and Certificates:Authentic katana often have the swordsmith's signature engraved on a part of the blade, along with certificates and detailed descriptions of the manufacturing process.
  • Materials:Real katana use carefully selected materials, with the blade typically forged from multiple layers of steel of different hardnesses to achieve both sharpness and durability. Imitations often use single, low-quality materials.
Assessing the Seller's Reliability
  • Reviews and Feedback: Before purchasing online, carefully study the seller's reviews and buyer feedback. A reputable seller usually has positive reviews and detailed buyer feedback.
  • Expertise: A seller knowledgeable about katana will provide extensive product information and can answer various questions about katana. If the seller knows little about the product, it's likely they are selling fakes.
Observing Specific Details of the Katana
Hamon (blade pattern)

The hamon of a real katana forms naturally during the smelting and cooling process, making each katana's hamon unique. Hamon is not only an aesthetic feature but also showcases the swordsmith's skill. The hamon on fake katana is often added post-production, for example, through etching or painting, and tends to look too uniform and deliberate.

Hada (blade folding marks)

The blade of a real katana will display textures formed during the metal folding and forging process, known as Hada. The presence of Hada indicates that the blade has been folded and forged multiple times, increasing its strength and flexibility. Fake katana usually have smoother blades without these naturally formed textures, or the textures appear artificially made.

Tsuka (handle inspection)

The interior structure of a real katana's handle is complex, usually wrapped with sharkskin (Same) and tightly wound with ribbon (Ito), all done by hand, showing slight irregularities. Fake katana have much simpler handles, possibly using low-quality materials for wrapping, with ribbon winding that may be loose or too neat, appearing stiff.

Verifying Accessories and Decorations

Accessories of a real katana, such as the scabbard (Saya) and the mouth of the scabbard (Koiguchi), are also handmade using high-quality materials, perfectly matching the blade. Fake katana's accessories and decorations often use cheap materials, are crudely made, and poorly detailed, possibly not matching the blade.

Studying the Swordsmith's Signature (Mei)

The signature of the swordsmith (usually located on the tang of the blade) is an important clue for authentication. Each swordsmith's signature is unique and can be compared with historical records and databases for authenticity. Fake katana might also have signatures, but these are often arbitrarily inscribed, lacking the artistry and precision of historical swordsmith signatures.


The process of identifying genuine and fake samurai swords is challenging, but through meticulous observation and study, you can significantly reduce the risk of being deceived. I hope my experience can help you be more confident and wise in your search for the samurai sword that truly belongs to you. Remember, patience and thorough research are your best weapons. Purchasing a samurai sword is an important investment and worth the time for in-depth research and consideration.
