It starts from a mythological age, then describes five Emperors after Amaterasuomikami (the Sun Goddess) and successive Emperors after Emperor Jinmu follow them (however, it differs from current imperial genealogy in that Empress Jingu is treated equally with Emperor and deposed Emperors like Emperor Kobun, Emperor Chukyo, Emperor Gomurakami of the Southern Court (Japan), Emperor Chokei and Emperor Gokameyama are excluded from the successive Emperors).
内容は神代に始まり、天照大神以下の5代を掲げ、神武天皇以下の歴代をそれに続ける（ただし現在の皇統譜と異なり、神功皇后を天皇に準じた扱いとする一方、廃帝の弘文天皇や仲恭天皇、南朝(日本)の後村上天皇・長慶天皇・後亀山天皇を歴代外とする）。
