Kon'e

The Kon'e (袞衣) is a type of formal court robe traditionally worn by the Emperor of Japan. It corresponds to the Chinese gǔnfú (袞服), a ceremonial robe for emperors featuring dragon embroidery, used during major state rituals in ancient China. In Japan, the Kon'e was worn together with the Benkan (冕冠; imperial crown) during important court ceremonies such as the Sokui no rei (即位の礼; Enthronement Ceremony) and the Chōga (朝賀; New Year's imperial audience).

In China, the robe was also known by the classical expression xuányī xūncháng (玄衣纁裳, lit. 'dark robe and red skirt'), referring to its black upper garment and light red skirt. In contrast, the Japanese Kon'e features red garments for both the upper and lower sections. A distinctive characteristic of the Japanese style is the way the mo (裳)—a mid-length ceremonial wrap skirt—is worn over the hakama (袴; traditional trousers), creating a uniquely Japanese configuration of lower-body garments.

The Kon'e remained in use until the enthronement of Emperor Kōmei in 1847. Beginning with Emperor Meiji, the official attire for enthronement ceremonies became the Kōrozen no gohō (黄櫨染御袍; robe dyed in yellow sappanwood).

The term Kon'e (袞衣) is an abbreviation of Konryō no Gyoi (袞龍御衣), which means a "dragon-embroidered ceremonial robe". Originating in China, the Kon'e was a ceremonial robe adorned with dragon motifs. The Book of Songs (Shijing) mentions such a robe in the "Bin feng" section, describing King Cheng of Zhou wearing it to greet the Duke of Zhou.

The Rites of Zhou (Zhouli), in the "Ministry of Spring" section, states: "When offering rites to former kings, [the emperor] wears the Kon'e and Benkan (冕冠)." A commentary adds that the character "Kon" specifically refers to garments embroidered with coiled dragons.

In Japan, the Kon'e became the emperor’s most formal court attire and was worn at ceremonies such as the enthronement ceremony and the Chōga (朝賀). The outfit consisted of a wide-sleeved outer robe (大袖, ōsode), an inner robe (小袖, kosode), and a pleated ceremonial skirt called mo (裳). Both the ōsode and mo were embroidered with the twelve imperial insignia, known in Japanese as Jūnishō (十二章), a set of symbolic emblems representing imperial authority, including dragons. Until the enthronement of Emperor Kōmei, the Kon'e and Benkan were worn together in such rituals, and the complete ensemble was known as Konben (袞冕), Benpuku (冕服), or Konben Jūnishō (袞冕十二章).

The Chinese equivalent traditionally followed the xuányī xūncháng (玄衣纁裳, lit. 'dark robe and red skirt') standard—featuring a black upper garment and a red lower one. In contrast, the Japanese Kon'e was entirely red. One theory attributes this color scheme to early Sui dynasty practices described in the Book of Sui. However, the Japanese adoption of the Kon'e occurred during the Tang dynasty, whose legal clothing code retained the black-and-red configuration. Although Emperor Wen of Sui (Yang Jian) altered court dress for audiences to an all-red format, ceremonial robes such as the Kon'e remained unchanged.

Another theory links the red color to solar symbolism. The Japanese Benkan features a sun-shaped ornament not found in Chinese counterparts, possibly signifying the emperor’s status as “Son of the Sun.” From this perspective, the all-red color may have been chosen to represent the sun, aligning with Japan’s image as the “Land of the Rising Sun.”
