History of Japan
Razan's successor as the Tokugawa's chief scholar was his third son, Gahō. After Razan's death, Gahō finished work his father had begun, including a number of other works designed to help readers learn from Japan's history. In 1670, the Hayashi family's scholarly reputation was burnished when Gahō published the 310 volumes of "The Comprehensive History of Japan" (本朝通鑑, "Honchō-tsugan").
