Authentic Japanese Sword

Ninja Weapon Museum is run by Tonbo8 CO,LTD., which also has another online shop called Samurai Museum Shop. While Samurai Museum Shop deal with only certified authentic Japanese swords, Ninja Weapon Museum Shop sells ones with no certificates. All the authentic Japanese swords listed on this website are registered under the board of education in each prefecture in Japan. That means they passed the examination held by the board of education and are guaranteed as traditionally hand-forged Japanese swords. You can appreciate the beauty of the Japanese sword with affordable prices. All the authentic Japanese swords were traditionally hand-forged and made of Tamahagane carbon steel. We will be happy to help you own a piece of Samurai history.
