The most expensive Japanese sword ever sold is the Yamatorige, a 13th-century National Treasure tachi that Setouchi City in Japan bought from a private collector in March 2020 for about 500 million yen, roughly $4.6 million. The highest price for a true katana is the Yamanbagiri Kunihiro, bought for 300 million yen (about $2 million) in March 2024, and the public auction record still belongs to a Kamakura blade that sold for $418,000 at Christie’s New York in 1992. This countdown ranks the ten priciest katana and their close cousin the tachi with a documented sale price, as of November 2026.
A quick note on terms. The tachi is the older, longer and more curved sword worn edge down by mounted samurai. The katana, worn edge up through the belt, replaced it from the 15th century, and many old tachi were later shortened and remounted as katana. Collectors treat them as one family, so we do too.

10. Yamato school katana: $23,750
The Yamato tradition is the oldest of the five classic schools of Japanese swordmaking, tied to the temples around Nara. Its smiths made blades for warrior monks, with a straight-grained steel pattern that experts can spot at a glance.
This katana sold at Christie’s in 2007 for $23,750, above its estimate of $15,000 to $20,000. That makes it the entry point for this list and a fair picture of what a good, papered old blade from a respected school costs at a major auction house.
How we valued it: final auction price as reported; whether it includes buyer’s premium was not stated.
9. Juyo katana by Sekishu Naotsuna: $134,500
Sekishu Naotsuna worked in Iwami Province in the 14th century and is counted among the ten great students of Masamune, the most famous swordsmith in Japanese history. This blade dates to the Nanbokucho period, when Japan had two rival imperial courts and swords were in constant use.
The blade was designated Juyo Token, Important Sword, by the Society for the Preservation of Japanese Art Swords, a ranking only a small share of old blades receive. Bonhams sold it in New York on 16 October 2012 for $134,500, within its estimate of $125,000 to $150,000.
How we valued it: final price including buyer’s premium from the auction result.
8. Okanehira tachi: about $180,000
The Okanehira is a tachi made around the 12th century by Kanehira of Bizen Province. The blade is long and heavy, and a designated National Treasure of Japan. Experts often name it among the finest swords ever made.
In 1967, the Japanese state reportedly bought it from its private owner for 65 million yen, about $180,000 at the exchange rate of the time. That was a huge sum for 1960s Japan. Adjusted for inflation and the stronger yen, it would be many times higher today.
How we valued it: reported purchase price in yen, converted at the fixed 1967 rate of 360 yen to the dollar; we found only one detailed account, so we treat it as approximate.
7. Bizen tachi signed Nagamitsu: about $193,000
Nagamitsu led the Osafune school in Bizen Province in the late 13th century, the golden age of the Japanese sword. Signed Nagamitsu blades are prized because so many old swords lost their signatures when they were shortened. This one is a Kamakura period tachi with its signature intact.
Christie’s sold this blade in 2007 for £96,500, about $193,000 at the exchange rate of that year.
How we valued it: sale price in pounds, converted at 2007 rates.
6. Nagasone Kotetsu katana: $239,400
Nagasone Kotetsu started as an armor maker and turned to swords in his fifties, in 17th-century Edo, today’s Tokyo. His blades became so famous for cutting power that Kotetsu signatures are among the most forged in the market. A genuine one, with papers, is a serious trophy.
This early Edo katana, signed Nagasone Okisato Nyudo Kotetsu, sold at Christie’s New York in 2022 for $239,400. It is the highest katana result at a Western auction house in the last five years that we could document.
How we valued it: total with premium from a compiled list of auction results.
5. Katana signed Kotetsu: about $240,000
Another Kotetsu, another near quarter-million price. That two blades by the same smith sold six years apart within a few hundred dollars of each other says a lot about how stable the top of the antique sword market is.
This katana sold at Christie’s in 2016 for about $240,000.
How we valued it: price from a compiled list of auction results; the original lot page was not available to us, so the figure is approximate.
4. Tachi by Bizen Nagamitsu: about $350,000
The second Nagamitsu on the list, and a reminder of how much the Osafune masters dominate the high end. Long, graceful and with the clove-shaped temper line the Bizen smiths made famous, a top Nagamitsu tachi is what serious collectors in Japan and abroad wait years to buy.
This blade sold at Bonhams in 2015 for about $350,000, the highest result for a Japanese sword at a Western auction house since the Compton sale.
How we valued it: reported auction price from a compiled record of results; we could not open the original lot page, so we list it as approximate.
3. Kamakura period blade, Compton Collection: $418,000
Walter Ames Compton, an American physician and business executive, built one of the greatest collections of Japanese swords outside Japan. When Christie’s New York sold the first part on 31 March 1992, the session brought about $8 million, a world record for an auction of Japanese works.
The top lot was a 13th-century Kamakura steel blade that sold for $418,000 to a European collector, a world record for a Japanese sword at auction. Some sources credit it to Masamune himself, which we could not confirm. More than three decades later, no katana or tachi has beaten it at a public auction.
How we valued it: auction price published at the time of the sale.
2. Yamanbagiri Kunihiro katana: about $2 million
Horikawa Kunihiro made this blade in 1590. Its name means “mountain witch cutter,” from a legend that an earlier sword it was copied from had slain a mountain witch. Technically an uchigatana, the classic katana form, it, and was designated an Important Cultural Property in 1962.
The sword became famous to a new generation through a popular online game in which swords appear as characters, and fans flocked to see it in Ashikaga, where it was made. On 6 March 2024, the Ashikaga Citizens’ Cultural Foundation bought it from a private owner for 300 million yen, about $2 million. Part of the money came from crowdfunding and hometown tax donations.
How we valued it: disclosed purchase price in yen, converted at March 2024 rates.
1. Yamatorige tachi: about $4.6 million
Yamatorige, which means “mountain bird feathers,” is a tachi from the 13th-century Ichimonji school of Bizen. Its temper line rises and falls like the feathers of a pheasant, which gave it the name. It belonged to the Uesugi family, one of the great warlord houses, and has been a National Treasure since 1952.
When a private collector in Okayama agreed to sell, Setouchi City launched a campaign to bring it home to the region where it was forged. The city council approved the purchase on 17 March 2020 and the sword arrived a few days later. The price was reported at about 500 million yen, around $4.6 million, raised largely through donations. No Japanese sword has a higher price that we could verify.
How we valued it: purchase price in yen as widely reported, consistent with the city’s published fundraising target of about 513 million yen, converted at 2020 rates.
Not sold but valued: a tachi linked to the warlord Fukushima Masanori is often quoted online at $100 million. We found no auction record, sale document or credible buyer for that figure, so it is not ranked.
Records set in 2025 and 2026
No katana or tachi has beaten the records above in 2025 or 2026. The biggest event of the period was Sotheby’s sale of the Paul L. Davidson Collection in New York in March 2025: 74 lots of swords and armor, led by a katana attributed to Awataguchi Kuniyasu from around 1200. The sale reportedly brought about $1.45 million in total, with roughly six lots in ten finding buyers. That points to a deep but price-sensitive market, where top papered blades sell and average ones are left on the table.
What drives these prices
- Age and the golden era. At least six of the ten blades here were forged before 1400. Kamakura period swords from Bizen and Yamato are the blue chips of the field.
- Official rank. National Treasure, Important Cultural Property and Juyo papers act like a grade. A designated blade can be worth ten times a similar sword without them.
- Japan buys its swords back. The two most expensive sales were to Japanese cities and foundations, not private bidders. National Treasures cannot leave Japan, which shrinks the buyer pool and makes public campaigns decisive.
- A signature is gold. Many old blades were shortened and lost their signed tang. An intact signature by a master like Nagamitsu or Kotetsu adds a large premium.
- Pop culture now counts. The Yamanbagiri campaign was driven by fans of a sword-themed game, a new kind of buyer energy the old market had never seen.
