Inside the Tokyo Dealers Auction

Several times each year, specialized dealers and collectors gather in Tokyo to participate in private auctions dedicated to Japanese swords, armor, and historical artifacts.
These events offer access to pieces rarely seen outside Japan and provide an opportunity to connect directly with dealers, restorers, and collectors deeply involved in the preservation of Japanese history and craftsmanship.
At these auctions, every item undergoes careful examination, with specialists evaluating its authenticity, condition, provenance, and historical significance. Many of the pieces presented have remained in private collections for generations and are seldom available on the international market.
Our presence at these events allows us to source exceptional Nihonto and samurai-related artifacts directly from Japan, ensuring authenticity and offering our clients access to unique pieces that would otherwise be difficult to acquire outside the country.
Beyond the acquisition of rare items, these gatherings provide valuable insights into the evolving Japanese sword market, emerging collecting trends, and the ongoing efforts dedicated to preserving the legacy of the samurai for future generations.
For collectors, enthusiasts, and historians alike, the Tokyo dealers auctions represent a unique gateway into a world where tradition, craftsmanship, and history continue to be celebrated and preserved.

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!
