About us

SupeinNihonto is a project materialized after several years dedicated to the classic martial arts of Aikido, Kendo and Iaido, but above all fascinated by the collecting of Japanese weapons and armors, works of art of such a amazing period that intrigue millions of people around the world.

Seeing the difficulty we faced in acquiring authentic samurai swords beyond all the Asian and European replicas and copies that have been going around the world during the last decades, we decided to dedicate ourselves body and soul to find a group of Japanese suppliers that could help us in this task. So we started to study the types of Japanese weapons and armour and their different qualities, we became even more interested in Japanese readings and culture and in the most practical and affordable methods of importing with the help of a group of contacts we could trust to start this arduous journey. All our pieces comes with the certificate of authenticy of Supein Nihonto.

For some time now we have been travelling to Japan two or three times each year and we search through the Japanese flea markets that house these types of pieces in search of interesting objects and we meet with contacts in different parts of the country.

We have customers all over the world, but more generally in Europe, where countries such as France, Italy, the Netherlands, Belgium and Germany have a large number of collectors. We try to supply them through our articles in European auctions or directly by finding interesting pieces that they can request.

The intention of this page is to provide to any person who wants to have in his possession an authentic japanese weapons and armors, from Katanas to Wakizashis passing by Tantos or Naginatas; besides other pieces of equal historical and artistic value as Koshiraes, Tsubas, fuchi and kashira, etc. In addition to other items related to the life of the samurai and feudal Japan with a high artistic value as Inros, lacquers, Netsukes and of course samurai armor and its most iconic pieces: the Kabutos.

 Our goal is to offer samurai weapons and armor for almost every budget with an unbeatable price/quality ratio. With constant travel to Japan, a great daily effort and a good reputation among the most important distributors in Japan that allows us to visit places where most Europeans are forbidden, we can get the best of both worlds: Fast delivery, genuine and premium items and prices you can only find with a great reputation among the industry and Japanese suppliers and closer friends.

We strive to search pieces of all kinds so that everyone has the option to buy an authentic piece: from avid collectors with high budgets to first time buyers who may just want to have an affordable piece to display in their home or business and in this way bring our passion to the rest of the westerners.

Our aim is that when buying a piece in SupeinNihonto our customers can be confident that it is a real piece made by authentic Japanese forgers using traditional forging techniques and quality materials such as Tamahagane, the common steel used to make this type of piece.

I was served by the owner, my namesake Eric. It's clear he's passionate about what he does. Purchasing the Kiyomitsu Horimono katana was easy, and he provided personalized and very professional service, quickly answering all my questions. Shipping was also fast, and everything arrived perfectly packaged. I recommend this shop to any collector or enthusiast looking for authentic Japanese pieces with a guarantee of quality and authenticity.

I had been looking for a tachi with a lot of curvature for a long time and I called Supein Nihonto. They didn't have any tachi with the sori I was looking for, but I was treated with a lot of love and professionalism and we were talking for a long time. The next day I received a call from the shop, telling me that they had received new swords and that there was a tachi with a lot of sori. That same afternoon he already had a lot of photos of the sword and its measurements. I found the price good, especially if I compared it to other Spanish sellers of Nihonto. The shipment took a day and the package arrived in perfect condition, as the person in charge of the packaging puts a lot of effort into the work and the result is a strong packaging. Without a doubt, Supein Nihonto is my 100% recommendation!

Supein Nihonto is a well informed, serious and reliable dealer. I could contact them very easy and they answered to all my questions and inquiries. They gave me all the information I needed and now I’m a happy owner of a real katana which I cherish as a piece of art. The shipping was really fast and the katana was really well protected. You can buy from this company without any concerns.
