His best remembered work is the Gadō Yōketsu, a Kanō school history and training manual.
Kanō Yasunobu was born in Kyoto on the 1st day of the 12th month of the 18th year of Keichō (10 January 1614).
His father was Kanō Takanobu (1571–1618)[1] whose two elder sons Tan'yū and Naonobu moved to Edo (modern Tokyo) to become goyō eshi [ja], an exclusive position painting for the Tokugawa shogunate.
The Kyoto line continued after Takanobu's death in 1618 under Kanō Mitsunobu's son Sadanobu, who adopted Yasunobu as he had no heir.
Before this book's publication, Kanō techniques were passed down orally from master to apprentice, and there was disunity in the teaching methods of the school's branches.
