Shinchō kōki

Shinchō kōki (信長公記^?), is the chronicle of Oda Nobunaga, compiled in Edo period based on records by Ōta Gyūichi (太田牛一^?), a warrior who followed Nobunaga. Shinchō kōki covers from 1568, when Nobunaga entered Kyoto until he died in 1582. The compiled chronicle consists of 16 volumes and is considered "mostly factual" and "reliable". There are number of manuscripts with different titles, as Azuchiki (安土記^?) and Shinchōki (信長記^?). The Chronicle is not only often quoted on the subjects related to Oda Nobunaga himself, but on other subjects as well, such as the art of tea.

Reflecting the popularity of Oda Nobunaga, versions of the Chronicle re-written in modern Japanese that were published in recent years have sold nearly ten thousand copies all together.
