Karesansui 枯山水 (dry landscape gardens, also known as rock gardens and waterless stream gardens) are typically associated with Zen Buddhism, and often found in the front or rear gardens at the residences (houjou 方丈) of Zen abbots.
The main elements of karesansui are rocks and sand, with the sea symbolized not by water but by sand raked in patterns that suggest rippling water.
Representative examples are the gardens of Ryoanji Temple in Kyoto.
