Japanese dry landscape garden case studies

Quick answer：

Dry landscape gardens, known as 'kare-sansui' in Japanese, are a traditional form of Japanese garden design that emphasizes the use of rocks, sand, and sometimes gravel to create a representation of natural scenery. Case studies of these gardens often examine their historical significance, design principles, and the way they are used to reflect the Japanese philosophy of nature and impermanence. Some notable examples include the Ryoan-ji rock garden and the gardens at the Katsura Imperial Villa.
