The term 'dry landscape' refers to 'kare-sansui' in Japanese, a traditional Japanese garden design that features carefully raked gravel or sand to represent water, often accompanied by stones placed to represent mountains. The concept of 'imperfect beauty' in kare-sansui reflects the Zen philosophy of accepting imperfection and finding beauty in simplicity and naturalness. The gardens are designed with deliberate asymmetry, with elements that are slightly uneven or off-center to convey a sense of natural, rather than perfect, beauty.
