Haiku, Volume 4: Autumn-Winter does not stray from the format used in volumes two and three of the series. As the title states, this volume focuses on haiku that were inspired by the autumn and winter seasons, which are placed in seven major categories that are listed below. Many kigo are identified for each of these categories, including examples of haiku that utilize the kigo and commentary by Blyth himself. A great variety of haiku poets are included in the series, but there is no shortage of works written by the four masters of haiku: BashU, Buson, Issa, and Shiki. The consistency of this series helps to keep these volumes feel like one consistent work where haiku of any season can be enjoyed and understood!
