Japanese Sword Market Trends 2025 — What's Rising, What's Falling

2026 Japanese Sword Market Overview — Trends Collectors Should Know

The Japanese sword trading market has been experiencing unprecedented vitality in recent years. Domestic and international demand interact in complex ways, and it is not uncommon for certain items to be traded at prices far exceeding those from several years ago. On the other hand, the market as a whole is not uniformly rising—the situation is that certain categories are thriving while others are stagnating. This article examines the current market trends as of 2026 and provides concrete explanations of what is rising and what is stagnating.

Surging Categories — Game Culture and Inflow of Foreign Capital

The most notable upward trend is seen in extant works by swordsmiths featured in the popular game "Touken Ranbu -ONLINE-." In particular, tachi and tanto attributed to Sanjō Munechika (mid-Heian period) and Awataguchiyoshimitsu (late-Kamakura period) attract competitive bidding whenever they appear at auction, with hammer prices sometimes reaching 1.5 to 2 times the pre-sale estimates. By acquiring new collector demographics among younger and female audiences, demand has emerged in price ranges that were previously absent from the traditional sword enthusiast market.

Similarly, prices for NBTHK (Japanese Art Sword Preservation Society) Important Sword designations are rising steadily. While Important Swords rank one tier below Especially Important Swords, they are works that have passed assessment criteria close to the highest standards for Japanese swords, and possess high credibility as investment objects. Due to low authentication risk and ease in finding buyers upon future sale, purchases for asset preservation purposes by wealthy collectors are increasing.

The inflow of foreign capital is also a noteworthy factor. Collectors from North America, Europe, and Southeast Asia are actively participating in domestic auctions, riding the wave of yen weakness, and with an increase in auction houses offering foreign-language services, international price levels are being driven upward. In particular, fine examples of Bizen tradition and Soshu tradition kotou are increasingly being purchased by overseas buyers, intensifying competition with domestic collectors.

Stable Categories with Enduring Popularity

Works by representative swordsmiths of the Five Traditions (Yamashiro tradition, Yamato tradition, Bizen tradition, Soshu tradition, and Mino tradition) maintain stable prices over the long term. The Soshu tradition works of Masamune and Sadamune, the Bizen tradition works of Nagamitsu and Kagemitsu, the Osafune lineage of Kanemitsu and Toromitsu, and the Hizen Tadayoshi lineage have established universal evaluations that are resistant to trends of the era.

Signed blades with Tokubetsu Hozon (Special Preservation) or higher certificates have high market liquidity and excellent convertibility. They provide the confidence of being held as the core of a collection while being sold if necessary, and exist as a "benchmark currency" that can meet the diverse needs of both beginners and advanced collectors.

Moreover, demand for high-quality tanto is particularly increasing. Due to their compact size, they are easy to store even with limited display space, and more collectors are transitioning from larger swords to tanto as the collector base ages. Combined with limited circulation of fine examples, premium prices appropriate to quality are being maintained.

Categories Requiring Caution — Market Pitfalls

Even though the market as a whole is buoyant, there are categories that require careful discernment.

Production-type Bizen late-period swords (utilitarian blades mass-produced from the Northern and Southern Courts through the end of the Muromachi period) remain in a state of oversupply. Despite their historical significance, they receive low assessment grades due to coarse forging and numerous flaws, and often fail to achieve desired prices at sale. When purchasing, future liquidity should be carefully considered.

Unsigned shinkatana and shinshinkatana also require careful handling. Unsigned blades have weak authentication guarantees, and their value is heavily dependent on the grade of the certificate. Unsigned blades certified only as Hozon (Preservation) carry higher risk of price degradation in the secondary market compared to Tokubetsu Hozon or Important designations. At a stage where one cannot personally evaluate the blade's jigane, hamon, and sugata, it is wise to avoid purchase unless the provenance is highly trustworthy.

Furthermore, in recent years, counterfeit swords and replicas have become increasingly sophisticated, with reports of less experienced collectors inadvertently purchasing fakes at high prices. Particular caution is warranted with swords of unknown provenance.

Three Indicators for Reading the Market

First are results from major auctions. The bidding records of the Tokyo Art Club and Osaka Art Club are the most reliable sources for understanding real-time prices for specific swordsmiths or periods. Recently, some auction results have been made available online, making information gathering easier.

Second are trends in NBTHK assessment results. By tracking the pass rates of each assessment held several times per year and changes in the swordsmiths receiving priority evaluation, one can grasp the current value framework.

Third are exchange rates and numbers of international visitors to Japan. During periods of yen weakness, overseas purchasing interest increases and domestic prices rise. Conversely, if the yen strengthens, foreign buyer activity slows and adjustments may occur.

Outlook for 2026 and Beyond — Recommendations for Collectors

The 2026 market shows clear "polarization." Fine works, pieces by renowned swordsmiths, and certified specimens have steady demand with rising prices, while mid-to-lower-tier pieces have few buyers and remain soft.

For those forming a collection for the first time, I strongly recommend signed blades with certificates (at least Hozon) over unsigned inexpensive swords. If your first blade is one that is fairly valued in the market, it will become a benchmark for learning and inform future purchasing decisions.

Furthermore, to engage with the market over the long term, it is important to develop your own area of specialization, such as "late-Kamakura Bizen pieces" or "Hizen blades." This deepens your knowledge and connoisseurship, making it easier to avoid mismatched purchases.

Japanese swords are not mere investment objects, but cultural treasures embodying centuries of history. While keeping abreast of market trends, the best path to a rich experience in this market is to deepen your aesthetic sensibility and historical understanding, and cultivate your collection from a long-term perspective.
