The whole world is composed of nine mountains and eight oceans, according to the Buddhism cosmic view expressed in the myth of Mt. Sumeru. In representing this Buddhist image in the garden, a stone arrangement may be made symbolizing the nine mountains and eight oceans, or a single stone called kusen hakkai ishi is placed in a pond. The stone of the nine mountains and eight oceans in the Kyōkochi pond at Rokuonji temple (Kinkakuji) is well known.
