How much does a real Japanese sword cost?

Genuine blades with NBTHK certification papers typically start around a few thousand US dollars, most often an unsigned Edo-period wakizashi, and rise to museum level for Juyo-certified masterpieces. Anything sold new for a few hundred dollars is a decorative reproduction, not a nihonto.

Is it legal to buy a Japanese sword?

In most countries, yes. Blades exported from Japan are first deregistered and issued an export permit, paperwork the dealer handles. Confirm your own country's import rules before buying; the dealer you purchase from can advise on shipping to your destination.

What certification should I look for?

Current NBTHK papers, issued since 1982. From the first rank to the highest: Hozon confirms authenticity, Tokubetsu Hozon marks superior quality, Juyo Token designates important works, and Tokubetsu Juyo, chosen only from Juyo blades, is the highest rank. Older Kicho and Tokubetsu Kicho papers are largely disavowed by the NBTHK today; treat a blade with only those as unpapered.

Does NihontoWatch sell the swords?

No. NihontoWatch is the market's index, not a shop. Every listing links to the specialist dealer who holds the sword; you inquire and buy directly from them at their own price.

What counts as a Japanese sword?

To collectors, a Japanese sword means a nihonto: a blade hand-forged in Japan from folded steel, water-quenched to produce a visible temper line (hamon), and finished by a specialist polisher. Factory reproductions and decorative wall-hangers are a different product entirely; everything listed on this page comes from specialist dealers trading in the genuine article, from antique blades with centuries of history to registered work by contemporary smiths.

The market divides by form: the katana (long sword), the shorter companion wakizashi, the dagger-sized tanto, the older cavalry-style tachi, and rarer polearm blades such as naginata and yari. If you already know the form you want, the sword type directory is the fastest route in.

How the papers rank

Since 1982, the NBTHK (Society for Preservation of Japanese Art Swords) has issued four ranks of paper. Each is awarded after a panel examines the sword in Japan, and each step up is harder to reach. Fittings receive the same four ranks.

Beyond the papers: state designations

Kokuhō国宝 · National Treasure
Jūyō Bunkazai重要文化財 · Important Cultural Property
Jūyō Bijutsuhin重要美術品 · Important Art Object, a pre-war register (1933–1950)

Separately from the NBTHK, the Japanese state designates a small number of swords as cultural property. These are legal designations, not papers, and such swords may not leave Japan. How Tokubetsu Jūyō and the state designations compare: Same Smiths, Different Blades.

The NBTHK’s highest rank. It is chosen at a separate, less frequent examination, only from blades already designated Jūyō, and is judged on par with a nationally designated Important Cultural Property.

Old papers (before 1982)

No longer issued

Kichō貴重刀剣 · White paper
Tokubetsu Kichō特別貴重刀剣 · Green paper
Kōshu Tokubetsu Kichō甲種特別貴重刀剣 · Higher grade of Tokubetsu Kichō

Before the current system, the NBTHK issued Kichō papers on white paper and Tokubetsu Kichō papers on green paper, with Kōshu Tokubetsu Kichō as a higher grade of the latter. Collectors often call the whole family “green papers”.

None has been issued since 1982, and the NBTHK largely disavows them today: many blades that carry them fail when they are resubmitted. Treat a sword whose only papers are Kichō-era papers as unpapered, and ask the dealer whether it has passed a current examination. NihontoWatch counts these swords as unpapered.

The NTHK, a separate society, issues its own papers on a different scale. This guide describes the NBTHK.

How buying works here

NihontoWatch is not a shop; it is the market, aggregated. We track the inventories of specialist dealers in Japan, the US, and Europe daily, and every listing links back to the dealer who holds the sword, so you inquire and buy directly from the source at the dealer's own price. Listings carry the original photographs, measurements, signatures, and certification details the dealer published.

The inventories here come from established houses such as Aoi Art, Choshuya and Toushin, alongside dozens of smaller specialists, and every listing names its dealer.

Searching for a "samurai sword"? Same swords: collectors call them nihonto, and the classic samurai sidearm is the katana. We keep a short guide at samurai swords, explained.
