"Collection of Ten Thousand Leaves", The Man'yōshū contains 20 volumes and more than 4,500 waka poems, and is divided into three genres: "Zoka", songs at banquets and trips; "Somonka", songs about love between men and women; and "Banka" songs to mourn the death of people. These songs written by people of various statuses, such as the Emperor, aristocrats, junior officials, Sakimori soldiers (Sakimori songs), street performers, peasants, and Togoku folk songs (Eastern songs). There are more than 2,100 waka poems of unknown author. The signal, The Man'yōshū is widely regarded as being a particularly unique Japanese work, though its contained poems and passages did not differ starkly from its contemporaneous (for Yakamochi's time) scholarly standard of Chinese literature and poetics; many entries of the Man'yōshū have a continental tone, earlier poems having Confucian or Taoist themes and later poems reflecting on Buddhist teachings.
