High Quality Content by WIKIPEDIA articles! The Wagokuhen or Wagyokuhen ( ?, "Japanese Yupian") was a circa 1489 CE Japanese dictionary of Chinese characters. This early Muromachi Period Japanization was based upon the circa 543 CE Chinese Yupian ( "Jade Chapters"), as available in the 1013 CE Daguang yihui Yupian ( ; "Enlarged and Expanded Yupian"). The date and compiler of the Wagokuhen are uncertain. Since the oldest extant editions of 1489 and 1491 CE are from the Entoku era, that may approximate the time of original compilation. The title was later written with the graphic variant wa "harmony; Japan" for wa "dwarf; Japan".
