Kojiki or Furukotofumi also known in English as the Records of Ancient Matters, is the oldest surviving book in Japan.
The body of the Kojiki is written in Chinese, but it includes numerous Japanese names and some phrases.
The songs included in the Kojiki are in archaic Japanese written phonetically with Chinese characters.
A document claiming to be an older work, the Kujiki (which the Kojiki dates to 620 AD), also exists, but its authenticity is questioned.
Kojiki was presented by O-no-Yasum.
