Japanese garden is a haven for serenity and relaxation. Through thoughtful design of a variety of natural elements, Japanese gardens combine plants, rocks, animals and water in masterful combinations. Water features are often used as a focal point in the Japanese gardens. There are several different water features in Japanese gardens. One of the most popular is a pond. Japanese gardens with pond can add a dramatic accent into the gardens. Whether natural or man-made, ponds have been a main feature of Japanese water gardens in Shinto purification ceremonies since the sixth century. The shape of a Japanese pond garden can be nearly anything, though it is an important design principle that ponds not be in geometric forms like rectangles or circles, in large gardens. Ponds should look like a natural part of the landscape. If possible they are fed by natural springs or streams.
