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.
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.

Yes, every piece is sourced directly from Japan through trusted contacts, auctions, and specialized markets. Each item is guaranteed authentic, and many include official certifications such as NBTHK or NTHK. We never deal in replicas or imitations.
Every sword, armor, or fitting has its own history. Once sold, the item is removed from our website and cannot be restocked, as no two are alike. This is why we encourage clients to act quickly when they find a piece that interests them.
All items are carefully packaged to ensure preservation and are shipped securely with insured delivery. We offer both national and international shipping, using trusted courier services.
