Do you own an authentic Japanese Kabuto or antique samurai helmet that you are considering selling?
Supein Nihonto buys antique Japanese kabuto directly from private collectors, families, estates and dealers worldwide.
We are interested in historically important, unusual and collectible helmets, including complete examples, signed pieces, Kawari Kabuto and Kabuto with associated armor components.
If you are unsure exactly what you have, send us clear photographs for an initial assessment.
Front view, rear view, left and right side views, top view, interior of the helmet bowl, shikoro, maedate and fittings, fukigaeshi, signatures or inscriptions, clan crests, damage or restoration, storage box, certificates or documents.
If the Kabuto is displayed on a stand, include at least one full photograph of the complete helmet.
Kabuto with Menpō or armor components
We also consider Kabuto sold together with associated armor elements, such as:
Menpō
Hanbō
Nodowa
Shikoro
Maedate
Armor components
Storage boxes
Documentation
If the pieces appear to belong together, please send photographs of the complete group.
How the selling process works
Complete the form below and upload clear images of the kabuto and any associated documentation.
We review the helmet based on its construction, age, quality, condition and collector interest.
We may ask for more detailed photographs, dimensions or provenance.
If the kabuto is of interest and an agreement is reached, we will explain the next steps for payment and secure delivery.
Selling a Kabuto collection
We also buy collections containing multiple samurai helmets.
These may include:
Several kabuto
Kawari kabuto collections
Kabuto with menpō
Helmet parts
Maedate collections
Complete armor sets
Mixed samurai collections
For larger collections, overview photographs are enough for the first contact.
Not sure whether your Kabuto is authentic?
You do not need to authenticate it before contacting us.
Japanese helmets can be complex, and later reproductions, restored examples and composite pieces exist.
Send us clear photographs and any available information. We can determine whether the Kabuto is relevant to our area of specialisation.
Sell your Kabuto
If you own an antique Japanese kabuto or samurai helmet that you are considering selling, send us photographs for an initial specialist assessment.
Individual helmets, associated armor components and complete collections are welcome.

Compré una armadura Gusoku y todo muy bien, tenía algunas preguntas y Eric ha sido capaz de contestar todo lo que no sabía, llegó todo muy bien embalado y bastante rápido. El Kabuto es muy bonito y está muy bien conservado.

J'ai pu échanger de visu avec Eric. C'est un vrai passionné, qui maîtrise son sujet. Je le recommande vivement, surtout dans ce milieu ou le meilleur se mélange avec les pires escrocs

Hervorragende Dienstleistung, Qualität und persönliche Betreuung! Ich habe bereits drei Stücke von Supein Nihonto gekauft und hatte nie Probleme. Nach schlechten Erfahrungen mit anderen japanischen Händlern – lange Lieferzeiten und sogar ein verlorenes Paket – bin ich zu dieser Firma gewechselt. Ich werde ihnen treu bleiben und meine bereits beeindruckende Sammlung weiter ausbauen.

Ho acquistato da Eric un’armatura samurai di grande fascino e qualità, e l’esperienza è stata eccellente sotto ogni aspetto.
Fin dal primo contatto si è dimostrato estremamente professionale, competente e disponibile nel fornire tutte le informazioni richieste, accompagnandomi con trasparenza durante l’intero processo di acquisto. L’oggetto ricevuto corrisponde perfettamente alla descrizione e alle aspettative, con una cura nei dettagli che testimonia una profonda conoscenza del settore.
Ho particolarmente apprezzato la serietà, la correttezza commerciale e l’attenzione riservata al cliente, qualità oggi sempre più rare da trovare. La spedizione è stata accurata e l’armatura è arrivata in perfette condizioni.
Consiglio vivamente Eric a collezionisti, appassionati di arte e cultura giapponese e a chiunque sia alla ricerca di oggetti autentici e di alto livello.
Grazie ancora per questa splendida acquisizione che rappresenta uno dei pezzi più interessanti della mia collezione.

I had an excellent experience with Supein Nihoto. I purchased a katana and a wakizashi, and both pieces are truly beautiful — carefully selected and of remarkable quality. You can immediately see the attention to detail and the seller’s passion for what he offers.
The packaging was also exceptional: all the documentation was perfectly arranged in a refined envelope, which added a very elegant touch to the whole experience.
As a thoughtful gesture, he even included a small katana kake stand as a gift, which I greatly appreciated.
Beyond the objects themselves, the seller was very helpful, responsive, and clearly knowledgeable. His selection is outstanding, and you can tell he deals in genuinely fine items.
Highly recommended — I would definitely purchase from Supein Nihoto again

I received a beautiful tokubetsu hozon nihonto for Christmas from Supein. Actually my wife purchased the sword after receiving some helpful hints and recommendations lol. She knows absolutely nothing about nihonto but Supein walked her through everything honestly and I ended up with something beyond my dreams and expectations, honestly. The packing was exceptional, shipping fast and the sword itself a literal work of art. Supein has a lifetime customer now as my collection grows. Thank you!
