Adventure, ninja, and samurai stories make up the bulk of this collection, quite a few starring the character Sarutobi Sasuke. Others are biographies of famous warriors or adaptations of Edo tales. The original collection comprised two main series: Tatsukawa bunko (Tatsukawa Bunmeidō, Osaka) and Shūchin Okawa bunko (Ōkawaya Shoten, Tokyo).
