It is rich in biographies of busho (Japanese military commander) in the Sengoku Period and daimyo (Japanese territorial lord). (Especially the articles about the Muromachi period is said to be more excellent than those about the Edo period, and above all the descriptions ranging from the Onin War to the process of restructuring a feudal system were written well, because the author had to care about the Edo bakufu (Japanese feudal government headed by a shogun) during writing.)
戦国武将や大名などの列伝が充実している（特に江戸幕府への配慮を必要とした江戸時代の部分よりも室町時代の記事の方が優れているといわれており、応仁の乱から封建制の再構築の過程の執筆に力が入っている）。
