24 exceptional lots from Supein Nihonto, offered without reserve.
SupeinNihonto was born from years of dedication to traditional Japanese martial arts such as Aikido, Kendo, and Iaido, and a deep passion for collecting authentic samurai weapons and armor.
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
Legit dealer of Japanese treasures ! This man loves his work is not just reselling items, at first he is a collector and does this out of true passion.
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!
