You do not need to sell each piece individually or identify every object before contacting us.

We welcome enquiries concerning:

Private Japanese art collections
Inherited collections
Samurai armour collections
Japanese sword collections
Tosogu and sword fitting collections
Netsuke and inrō collections
Ukiyo-e collections
Mixed Japanese antique collections
Individual objects of particular historical or artistic interest

For larger collections, several general photographs and a brief description are often enough for an initial assessment.

Inherited japanese antiques?

It is common for Japanese swords, samurai armour, netsuke and other traditional works of art to pass through families without detailed information about their history or value.

You do not need to know exactly what you have before contacting us.

Send us clear photographs of the pieces, including any signatures, inscriptions, boxes, certificates or accompanying documents.

We can determine whether the objects fall within our area of specialisation and whether they may be of interest to Supein Nihonto.

Contact a specialist

How does selling to Supein Nihonto work?

Complete the form and upload clear images of the item or collection you are considering selling. For collections, overview photographs are useful as a first step.

We review the photographs and information provided. Depending on the object, we may request additional images, dimensions, documentation or photographs of particular details.

If the object or collection is of interest, we will contact you directly to discuss it further.

If an agreement is reached, we will explain the appropriate payment, documentation and shipping process. Larger or particularly important collections can be handled individually.

What should i send?

You do not need to prepare a professional catalogue.

Please provide whatever information you have available, such as:

General photographs of the object
Detailed photographs
Dimensions
Artist or maker, if known
Signatures and inscriptions
NBTHK or NTHK certificates
Other certificates or documentation
Original boxes or storage cases
Provenance or previous ownership
Known purchase history
General condition

If you know very little about the object, clear photographs are usually the most useful starting point.

Japanese swords with NBTHK or NTHK certificates

If your Japanese sword or sword fitting has documentation from the NBTHK, NTHK or another recognised Japanese organisation, please include clear photographs of the certificate.

These documents may contain important information concerning attribution, period, school or authenticity.

You can also send Japanese documentation even if you cannot read or translate it.

Submit for assessment

Why sell your japanese antiques to Supein Nihonto?

Supein Nihonto specialises specifically in authentic Japanese swords, samurai armour, tosogu and traditional Japanese art.

Unlike a general antique buyer, our activity is focused on historical Japanese objects and the characteristics that matter to collectors.

Depending on the type of object, our assessment may consider:

Historical period
Artist or school
Signature or mei
Materials
Craftsmanship
Condition
Originality
Provenance
Certification
Rarity
Collector interest

Our aim is to provide owners with a clear, professional and confidential way to offer individual objects or complete collections.

Not sure which category your object belongs to?

That is not a problem.

You may have inherited an object described simply as a “Japanese sword”, “samurai object”, “Japanese carving” or “Japanese print”.

You do not need to identify it yourself before contacting us.

Send us several clear photographs and we will review the object.

What our customers say

 Trustindex verifies that the original source of the review is Google. 我是一名常驻中国的室内设计师。当时我正在为一位客户的办公室寻找正宗的日本藏品，偶然了解到了Supein Nihonto。我们当时专门想找两套武士铠甲，将其作为空间的视觉核心。
整个合作过程中，埃里克提供了极大的帮助。他解答了我关于铠甲的各类疑问，包括铠甲的历史背景、尺寸规格、陈列方式以及物流运输等问题。尽管我们身处不同国家，他把所有事宜都处理得清晰明了。
铠甲如期送达，摆放在完工后的办公室里效果十分惊艳。最重要的是，我的客户对最终效果非常满意。
这次合作体验极佳。今后如果有室内设计项目需要采购正宗日本古董，我一定会再次选择这家。

 Trustindex verifies that the original source of the review is Google. 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.

 Trustindex verifies that the original source of the review is Google. 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.

 Trustindex verifies that the original source of the review is Google. 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

 Trustindex verifies that the original source of the review is Google. 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!
