日本刀Katana (Japanese sword)

A Japanese sword (日本刀, Nihontō, Nippon-; Japanese pronunciation:) is one of several types of traditionally made swords from Japan. Bronze swords were made as early as the Yayoi period (1,000 BC – 300 AD), though most people generally refer to the curved blades made from the Heian period (794–1185) to the present day when speaking of "Japanese swords". There are many types of Japanese swords that differ by size, shape, field of application, and method of manufacture. Some of the more commonly known types of Japanese swords are the katana, tachi, ōdachi, wakizashi, and tantō.
