The 'Taiheiki' has served as a source for countless works from the medieval period to the present day. It is a narrative that has shaped the image of samurai and, in effect, restricted the historical perception of Japanese people. This book, written by a rising scholar, uses the latest research to expose the fabrications of the 'Taiheiki' and the profound influence of its 'historical view' (shikan).

A 'Taiheiki Historical View' even stronger than the 'Shiba Historical View'
In addition to the truths and falsehoods of the 'Taiheiki,' the book strips away the influence of this 'historical view.' It provides a glimpse into the forefront of medieval historical research!
The images of samurai depicted in the 'Taiheiki,' such as Ashikaga Takauji, Nitta Yoshisada, Kusunoki Masashige, and Ko no Moronao, as well as the structure of the stories, have restricted the historical perception of Japanese people for centuries, from the medieval period to the early modern and modern eras, even influencing reality. For example, the Mito Domain's 'Dai Nihon Shi' relied on the 'Taiheiki,' and the 'Taiheiki historical view' led to ideologies like 'sonno joi' (revere the emperor, expel the barbarians) and the state-centric imperial ideology, starting with the image of Kusunoki Masashige and the framing of Ko no Moronao as the villain.
While it is an important historical document, it is a difficult story to handle due to its blend of fact and fiction. This book demonstrates the results of the struggle between historical studies and Japanese literature, while questioning our very own historical consciousness.
- Both Yamana Sozen and Tokugawa Ieyasu were members of the 'Ashikaga clan.'
- Kusunoki Masashige was associated with the Kamakura Shogunate.
- The battle with Takauji was a civil war within the Ashikaga clan. Yoshisada aimed for a 'third pole.'
