Karesansui, also known as Japanese rock garden or Zen garden, is a form of Japanese garden design that emphasizes the use of rocks, gravel, and often moss to represent a natural landscape. There are several books available that delve into the history, design principles, and artistic expressions of karesansui. Some notable titles include 'Karesansui: The Art of Zen Rock Gardening' by Takuma Nakahara, and 'Japanese Rock Gardens' by Junichiro Tanizaki and Takuma Nakahara.
