What our customers say
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 have no words to describe how I felt when I received my first Nihonto from Eric (one of my lifelong dreams has come true).

Gracias Alfredo, un placer. Espero seguir pudiendo ayudarte con las piezas en el futuro. Un saludo! 
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!

Gracias Javier, ha sido un placer poder hablar contigo y haber compartido opiniones. Te llevas una espada preciosa, siempre es un placer encontrar un sitio para una pieza de arte para alguien que la aprecie y la disfrute. Espero que sea la primera de una grran colección! Un abrazo. 
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.
