The Birth of Japanese Steel

Introduction of steelmaking techniques from China and Korea marks the beginning of Japan's legendary blade tradition.

This foundation would support centuries of unmatched blade craftsmanship.

The Samurai Sword Era

Japanese swordsmiths perfect the katana — a curved, single-edged blade that becomes the soul of the samurai.

Blade-making becomes a sacred art form, with rituals of purification before forging.

Edo Period: Swords to Plowshares

The Tokugawa peace brings stability — and sharply reduced demand for military swords.
