Supein Nihonto 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.
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 Supein Nihonto, 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.
