The chokut? ( 直刀 , 'straight sword') is a straight, single-edged Japanese sword that was mainly produced prior to the 9th century. Its basic style is likely derived from similar swords of ancient China. ^{[1] [2]} Chokut? were used on foot for stabbing or slashing and were worn hung from the waist. ^{[3] [2] [4]} Until the Heian period such swords were called tachi ( 大刀 ) , distinct from tachi written as 太刀 , as the latter refers to curved swords. ^[5]

History [ edit ]

The production of swords in Japan is divided into specific time periods: ^[6]

• J?kot? (ancient swords, until around 900 CE)
• Kot? (old swords from around 900?1596)
• Shint? (new swords 1596?1780)
• Shinshint? (new new swords 1781?1876)
• Gendait? (modern or contemporary swords 1876?present)

The tsurugi was the earliest type of sword made in Japan. ^{[7] [8]} The chokut? , on the other hand, was among the earliest types of sword to be forged in Japan, its basic style and forging techniques probably originated in ancient China and Korea. The chokut? was brought to Japan by way of Korean Peninsula and China in the Han dynasty times. ^{[9] [1]}

There are various types of chokut? in the Kofun period (300－538), and there are styles originated in China and styles unique to Japan. ^[7] The kant?-tachi ( 環頭大刀 ) is a Chinese style, characterized by a ring-shaped ornament shaped like a dragon or a phoenix on the tip of the handle. ^[7] The Kabutsuchi-tachi ( 頭椎大刀 ) is a unique Japanese style with a fist-like decoration on the tip of the handle. ^{[10] [7]} The rokkaku-s?t?ken ( 鹿角?刀? ) is also unique to Japan and is decorated with deer antlers. As the name suggests, this style is also applied to tsurugi . ^{[11] [7]}

The chokut? in various styles including these styles declined around the end of the Asuka period (593－710), and only the style called the h?t?-tachi (方頭大刀), in which the decoration on the tip of the handle was rectangular parallelepiped, survived from the Nara period (710－794). ^[12]

Chokut? typically come in hira-zukuri and kiriha-zukuri tsukurikomi (blade styles) which make them very distinct from later tachi and katana which rarely use these forms. Swords of this period are classified as j?kot? and are often referred to in distinction from Japanese swords. ^[6]

Chokut? as a weapon died out by the middle of the Heian period , in the 10th century. And as a weapon, it was completely replaced by the Japanese sword, which is known today for its deep and graceful curves. The first sword with this curve was called Kenukigata-tachi ( ja:毛?形太刀 ), which was made by improving Warabitet? ( ja:蕨手刀 ) used by Emishi in Tohoku region . ^{[13] [14]} And Kenukigata-tachi evolved into tachi , which became the mainstream of Japanese swords for a long time. ^[15]

Sugari no Ontachi [ edit ]

In today's Japan, straight swords made with the techniques after chokut? , are also called chokut? , and these are sometimes used in traditional ceremonies. The Sugari no Ontachi ( 須賀利御太刀 ^[16] ) is one of the chokut? made as an offering to Amaterasu , the main enshrined kami of Ise Grand Shrine , and one of the most gorgeous sword mountings among the chokut? . According to tradition, the building of Ise Grand Shrine and its sacred treasures have been recreated to the same specifications every 20 years since the seventh century. The Sugari no Ontachi was first described in the Kotai Jingu Gishikicho ( 皇太神宮儀式帳 ) compiled in 804, and it is believed that new decorations were added to the scabbard and sword fittings at each subsequent Shikinen Sengu (Rebuild every 20 years, 式年遷宮) to complete the design as we know it today. ^[17] The Sugari no Ontachi currently offered to Ise Grand Shrine was remade in 2013 and is thought to have accurately inherited the style of sword mountings from the Heian period (794－1185) and the forging method from the Sinto period (1596－1781). ^{[18] [19] [20]}
