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.
After facing the difficulty of finding genuine Japanese swords among the countless replicas available worldwide, we decided to take a different path. We began traveling regularly to Japan, building trusted relationships with local suppliers, and studying the history, craftsmanship, and quality of traditional Japanese weapons.
Today, we personally source pieces across Japan — from antique markets to private contacts – ensuring that every item we offer is authentic and carefully selected. Each piece includes our certificate of authenticity and reflects the artistry of traditional Japanese forging techniques.
Our mission is simple: to make authentic samurai weapons and armor accessible to both experienced collectors and newcomers, offering a balance of quality, trust, and fair pricing.
Handcrafted masks used in classical Noh theater, embodying the spiritual and dramatic essence of Japanese culture.
Finely carved miniature sculptures reflecting the elegance, symbolism, and craftsmanship of traditional Japanese art.

A traditional Nihontō is far more than a weapon. For centuries, Japanese swordsmiths developed forging techniques that transformed steel into objects of extraordinary beauty, balance, and cultural significance.
From elegant Edo-period katana to finely crafted tosogu and samurai armor, every piece reflects the spirit, aesthetics, and craftsmanship of historical Japan.
Many of the swords we offer retain original Japanese registration papers and preserve details such as handmade hamon, traditional polishing, and period koshirae carefully maintained through generations.

Supein Nihonto specializes in the import and sale of authentic Japanese samurai swords, armor, and cultural artifacts. All items are unique, genuine, and often come with certificates of provenance.

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.
