The Industrial Structure of Replica Swords and Iai Practice Swords: The Reality of Manufacturing and Distribution Alongside Genuine Swords

In the world of nihontō, alongside genuine swords as cultural assets, there exists an independent industry of replica swords and iai practice swords. At first glance, these two appear to be the same "sword," but they possess different industrial structures in every respect: legal regulation, manufacturing process, distribution channel, and customer base. This article organizes the reality of the replica sword and iai practice sword industry from an industry perspective.

What Is a Replica Sword? Legal Definitions and Product Categories

Under the Act for Controlling the Possession of Firearms or Swords and Other Such Weapons (Jūtōhō), "sword and similar articles" refers to swords, spears, naginata, and other items with a blade length of 15 centimeters or more. Replica swords, on the other hand, are a product category designed to fall outside this legal definition. Representative product categories include the following.

• Imitation sword (mogitō): Made of metal without an edge, it has the appearance of a sword but no cutting function.
• Iai sword (also "iai-tō" or "keikotō"): A mogitō designed exclusively for practicing iai and battōjutsu, with a blade made of non-ferrous metal such as zinc alloy and not used for test cutting; no registration certificate is required. Test cutting using materials such as straw mats and bamboo requires a shinken (a genuine nihontō), and the iai sword is for appreciation and kata practice.
• Replica swords as decorative items: Made of aluminum alloy or zinc die-cast, these circulate in the market.

These are legally distinguished from genuine nihontō (bijutsu tōken) and can generally be purchased and possessed without a registration certificate. This regulatory difference forms the foundation that establishes the replica sword industry as a market entirely separate from genuine swords.

The Reality of Manufacturing: Production Regions, Materials, and Processes

The main production regions for iai practice swords are Seki City in Gifu Prefecture and the adjacent cutlery industry belt in Aichi Prefecture. Seki City has long been known as a cutlery production center and holds one of the leading domestic shares in the mass production of iai swords, separate from genuine nihontō forging. Overseas, Longquan in Zhejiang Province, China, has become a major global production center for replica nihontō, and many inexpensive replica products are imports from that region.

The manufacturing process for domestic iai swords differs greatly from the forging of genuine nihontō. Special machine-grade cutlery steel is often used, and products are mass-produced through press forming and grinding. However, for high-end products, some manufacturers incorporate manual processes close to nihontō forging techniques, forming the upper segment of the practice sword market at price points of 100,000 yen or more.

Sword fittings such as the tsuka, saya, and tsuba are offered in a wide range of options, from plastic to high-quality items using genuine water buffalo horn and genuine ray skin. This high degree of customizability supports demand among iai enthusiasts for "a practice sword to their own taste."

Characteristics of Distribution Channels and Customer Base

The distribution of replica swords and iai practice swords operates through independent channels that barely intersect with the genuine sword industry. The main sales routes are as follows.

• Martial arts equipment specialty stores for iai and battōjutsu: The largest distribution hub; martial arts supply stores nationwide serve as the primary sales outlets for iai swords. These stores maintain close ties with dojos and offer a wide range of products from beginner to advanced practitioner.
• Online sales: Their share has grown in recent years, and purchases through manufacturer direct-sales e-commerce sites and martial arts equipment mail-order sites are becoming mainstream.

The customer base can be broadly divided into three categories.

• Practitioners of iai, kendo, and battōjutsu: The largest segment, with a clear need for practice purposes.
• Buyers for cosplay and photography prop purposes: Numbers have grown rapidly in recent years, and demand for replica swords to match anime and period drama costumes is driving the e-commerce market.
• Beginner-level buyers for interior decoration or collecting purposes: Many purchase replica swords as an entry point into the genuine sword market.

The price ranges are as follows.

Compared to the price range of genuine bijutsu tōken, which runs from hundreds of thousands to several million yen, the replica sword and iai sword market is centered on popular price points.

Coexistence and Interaction with the Genuine Sword Industry

The replica sword industry and the genuine sword industry basically occupy separate niches based on different legal regulations, price ranges, and customer bases. However, there is an interaction between the two that cannot be ignored.

It is not uncommon for enthusiasts who started with replica swords and iai swords to deepen their interest in genuine nihontō through continued martial arts practice and eventually transition to becoming bijutsu tōken collectors. This "entry-level to advanced" progression serves as an important customer cultivation pathway for the genuine sword market.

In overseas markets, on the other hand, the mingling of genuine and replica products has become an industry challenge. In particular, cases in which inexpensive Chinese-made replica swords are mislabeled and sold as "nihontō" on online platforms continue to arise, and industry associations have also pointed out the problem of its impact on the credibility of genuine nihontō products.

Trends in the iai population also affect the industry. The number of registered iai practitioners has been maintained at the scale of tens of thousands, forming a stable base of demand for practice swords. However, the declining birthrate and shifts in the martial arts population cast a shadow over medium- to long-term demand projections, and manufacturers are pursuing demand diversification by responding to cosplay- and content-related demand.

Conclusion

The replica sword and iai practice sword industry forms an independent market that supports the broad base of nihontō culture, while possessing legal regulations, manufacturing processes, and distribution structures different from those of genuine nihontō (bijutsu tōken). This market, in which domestic manufacturing centered on Seki City competes with inexpensive imported products, serves a diverse customer base comprising iai enthusiasts, cosplay demand, and beginner collectors. The interaction between the two industries — in particular, the migration of users from replica swords to genuine swords — carries important significance from the perspective of customer cultivation for the nihontō industry as a whole.
