This collection is a useful supplement to incomplete extant stories such as "Yoru no nezame" and "Hamamatsu Chunagon Monogatari (The Tale of Hamamatsu Chunagon)," not to mention stories such as "Mikakigahara," "Asakura," and "Amabito no moshiobi" that had been scattered and ultimately lost, and this fact makes Fuyo Wakashu a valuable document for the study of fictional stories in the Middle Ages (the times around the Heian period) together with "Mumyo Zoshi (Story Without a Name)."
『みかきが原』『あさくら』『海人の藻塩火』のごとき散逸物語はいうまでもなく、『夜の寝覚』『浜松中納言物語』のように不完全な姿で伝来する物語の欠巻を補うのに役立ち、『無名草子』と共に中古作り物語の研究資料として貴重。
