Six Codes (Chinese: 六法; pinyin: Liù Fǎ; Kana: ろっぽう; Hangul: 육법) refers to the six main legal codes that make up the main body of law in Japan, South Korea, and Taiwan.
The word roppō is a slightly adapted form of the word used in Japanese to describe the Napoleonic Code (ナポレオン五法典 Napoleon go-hōten) when it was brought over during the early Meiji period.
The Six Codes were introduced to China in 1905 after the reform and modernization of the Chinese legal system led by Cixi.
Such reform was based on the similar laws adopted in Germany, France, and Japan.
After the establishment of Nationalist Government, the Complete Book of Six Codes was passed on October 3 1928.
