This paper analyzes how the three rivers, Htuse River, Asuka River, Saho River, through the Nara Basin are expressed in Manyosyu. It can be found that whether the song was sang in Nara or not by comparing some volumes of Manyosyu which includes the three rivers with rest of the volumes which do not include three rivers. This can be explained that considering natural features of the seasons are more of experimental interest rather than ideological interest. Hantuse River and Saho River facilitated as the road for transporting trees during the removal of the capital. Asuka River was regarded as symbol of Hujiwarakyo, the Emperor`s palace, in the past. In some funeral songs, water plants waving in Asuka River was described as physical movement of male and female, Saho river was mentioned while describing a scene crossing Saho river as holding a monk`s funeral. Moreover, it also describes one`s grief for death of his wife as if he is shooting arrows to cormorant at Saho River. In some love songs, the intensive flow of Hutuse River was described as circulation of white, beautiful Nusa(Shinto offering of cloth). As in the funeral songs, the lovers are figured as water plants. The crying sound of Courser is representing Saho River. Finally, the image of Hatuse River and Asuka River surrounding mountain is decribed as god`s obi and it is an image of myth.
