Synonymous with quality, Japanese swords have been forged through generations of exacting tradition and craftsmanship. Famous according to skill of their swordsmiths, Japanese blades come in various designs including short tanto blades, straight tsurugi ones and the more recognisable curved tachi and katana blades. There are some 120 swords and sword mountings registered as National Treasures with close to half of them held in either private or public hands within Tokyo city. Here is a simple guide to where in Tokyo these National Treasure swords can be found.

Tokyo National Museum

The many tachi blades held by the Tokyo National Museum include the 10th-century Crescent Moon, one of the Five Swords Under Heaven. Another is a 14th-century blade once presented to Emperor Taisho. The aptly named 10th-century Monster Cutter deserves a mentions and so too the 12th-century Great Kanehira, named because of its prodigious size. The 13th-century Okada Slayer was used to kill. Katana blades at the museum include a famous Masamune blade from the 14th century featuring gold inlay as well as a 13th-century blade once held by the Kanze School of Noh theatre. A thick-bladed tanto was once owned by Tokugawa Ieyasu himself.
