Fuchi and kashira
Menuki pairs
Tsuba with matching fittings
Complete koshirae fittings
Sets sharing the same design or school
Fittings preserved together with a sword
If you have several pieces that appear to belong together, please photograph them both individually and as a group.
Matching sets can have greater collector interest than separated components.

NTHK papers

Material
Whether a signature is genuine
Whether the piece is certified
Its current market value
Clear photographs are usually enough to begin an initial review.
Complete the form below and upload clear photographs of the fittings and any documentation.
We assess the material, workmanship, condition, attribution and collector interest.
We may request additional photographs, measurements or provenance details.
If the pieces are of interest and an agreement is reached, we will explain the next steps for payment and secure delivery.

We also purchase complete collections of Japanese sword fittings.
These may include:
Tsuba collections

Fuchi-kashira
Kozuka
Kogai

For larger collections, you do not need to photograph every single piece individually at first.
Overview photographs and images of the most important items are enough to begin.
Not sure what type of fitting you have?
You do not need to identify the piece before contacting us.
Japanese sword fittings can be highly specialised, and distinctions between materials, schools and techniques are not always obvious.
Send us clear photographs and whatever information you have available.
We can determine whether the piece is relevant to our area of specialisation.
Sell your Tosogu
If you own antique Japanese sword fittings or a collection of tosogu that you are considering selling, send us photographs for an initial specialist assessment.
Individual pieces, matching sets, certified fittings 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!
