About us

SupeinNihonto was born from a lifelong fascination with Japanese martial arts, traditional craftsmanship, and the history of the samurai.

What began through years of practice in Aikido, Kendo, and Iaido gradually evolved into a deeper passion for collecting authentic Japanese swords, armor, and historical artifacts. During that journey, we discovered how difficult it was to find genuine pieces beyond the countless replicas and mass-produced reproductions that dominate the international market.

Driven by that challenge, we dedicated ourselves to building trusted relationships with dealers, craftsmen, and specialists across Japan. Over time, we immersed ourselves in the study of Nihontō, Tosogu, samurai armor, and Japanese history, learning not only how to identify authentic pieces, but also how to source them responsibly and respectfully.

Today, we travel to Japan several times each year, visiting antique markets, specialized dealers, and private contacts in search of swords and artifacts with historical, artistic, and cultural value. Every piece we offer is carefully selected with attention to authenticity, preservation, craftsmanship, and character.

Our collection includes authentic Japanese swords such as Katana, Wakizashi, Tantō, and Naginata, alongside Tosogu and traditional fittings including Tsuba, Koshirae, Fuchi Kashira, and Menuki. We also offer samurai armor, Kabuto, Inrō, Netsuke, lacquerware, and other objects connected to the culture and aesthetics of feudal Japan.

Over the years, we have supplied collectors throughout Europe and internationally, helping both experienced collectors and first-time enthusiasts acquire authentic Japanese pieces with confidence and transparency.

At SupeinNihonto, our goal is not simply to sell historical objects, but to preserve and share the craftsmanship, artistry, and spirit behind them.

Every item comes with a certificate of authenticity issued by Supein Nihonto.

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!

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!
