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

2026 Japanese Sword Market Overview—Trends Every Collector Should Know

The Japanese sword trading market is experiencing unprecedented activity. Domestic and international demand intersect in complex ways, and it is not uncommon for certain items to be traded at prices far exceeding those from several years ago. However, not everything is rising in value; the current reality is that categories are experiencing mixed fortunes. This article examines 2026 market trends in detail, explaining specifically what is rising and what is stagnating.

Rapidly Rising Categories—Game Culture and Inflow of Foreign Capital

The most prominent upward trend is found in extant works by sword makers featured in the popular game "Touken Ranbu -ONLINE-". In particular, tachi and tanto attributed to Sanjo Munechika (mid-Heian period) and Awaltaguchi Yoshimitsu (late Kamakura period) attract competitive bidding each time they appear at auction, with sale prices sometimes reaching 1.5 to 2 times the pre-auction estimate. Gaining new collector demographics—younger and female collectors—has created demand at price levels previously absent from the traditional sword enthusiast market.

Similarly, prices for NBTHK (Japanese Sword and Art Preservation Society) Certified Important Swords continue to rise steadily. Important swords rank below Specially Important Swords but are items that have cleared evaluation standards close to the highest level, offering high reliability as an investment target. With low authenticity risk and strong buyer interest at future sale, purchases by wealthy collectors for asset preservation purposes are increasing.

The inflow of foreign capital cannot be overlooked. Collectors from North America, Europe, and Southeast Asia are actively participating in domestic auctions, buoyed by favorable exchange rates, and with more auction houses now offering foreign language support, international price levels continue to rise. Particularly for high-condition old swords of the Bizen and Soshu traditions, foreign buyers increasingly win auctions, intensifying competition with domestic collectors.

Stable Categories with Enduring Popularity

Representative works by master smiths of the Five Schools (Yamashiro, Yamato, Bizen, Soshu, and Mino traditions) maintain stable prices over the long term. The following are representative combinations whose universal evaluation is established and resistant to period trends.

Signed blades with certificates at the Specially Preserved Sword level or higher show high market liquidity and excellent convertibility. They offer the peace of mind of being holdable as a collection core while remaining saleable as needed, and serve as a "reserve currency" accommodating diverse needs from beginners to advanced collectors.

Demand for high-quality tanto is particularly strong. Their compact size makes them easy to store even with limited space, and aging collectors increasingly transition from larger blades to tanto. Combined with limited circulation of premium examples, prices remain high according to quality.

Categories Requiring Caution—Market Pitfalls

Even with overall market activity, categories requiring careful assessment exist.

Mass-produced late Bizen swords (practical blades produced in quantity from the Northern and Southern Courts through the late Muromachi period) continue in an oversupplied state. Despite their historical background, they receive low evaluation due to rough forging and frequent flaws, and often fail to achieve desired prices at sale. When purchasing, future liquidity should be carefully considered.

Unsigned swords from the Shinto and Shinshinto periods also require careful handling. Unsigned blades have weak authenticity guarantees, with value heavily dependent on certificate grade. Unsigned swords graded only as "Preserved Swords" face higher secondary market depreciation risk compared to Specially Preserved or Important designations. Unless one can personally evaluate a blade's jigane, hamon, and form, it is wiser to refrain from purchase unless the provenance is trustworthy.

Furthermore, in recent years, imitation and replica swords have become increasingly sophisticated, with reports of inexperienced collectors mistakenly purchasing them at high prices. Particular caution is warranted with swords of unclear provenance.

Three Key Indicators for Reading the Market

1. Major auction results — Bidding records from the Tokyo and Osaka Fine Art Clubs are the most reliable source for learning real-time prices for specific smiths and periods. In recent years, some auction results have been published online, making information gathering easier.

2. NBTHK evaluation trends — By tracking pass rates in evaluations held several times yearly and changes in which smiths receive emphasis, one can grasp the current value framework.

3. Exchange rates and international visitor numbers — During periods of yen weakness, foreign purchasing interest increases, pushing up domestic prices. Conversely, if the yen strengthens, foreign buyer activity slows and corrections may occur.

Outlook Beyond 2026—Recommendations for Collectors

The 2026 market exhibits clear "polarization". Premium pieces, works by renowned smiths, and certified swords enjoy steady demand with rising prices, while mid-to-lower tier swords see little buyer interest and remain weak.

For those forming a collection for the first time, I strongly recommend signed blades with certificates (at minimum Preserved Sword designation) over unsigned, inexpensive swords. If the first blade one acquires is fairly evaluated by the market, it becomes a learning standard that informs future purchase decisions.

To remain engaged with the market long-term, it is important to develop your own specialty area—such as "late Kamakura period Bizen swords" or "Hizen blades". This deepens your knowledge and eye for quality, making it easier to avoid ill-fitting purchases.

Japanese swords are not mere investment vehicles but cultural assets bearing centuries of history. While keeping market trends in mind, deepening your aesthetic sense and historical understanding, and nurturing your collection with a long-term perspective, represents the best path to a rich experience in this market.
