In the east of the garden, on a peninsula, is an arrangement of stones designed to represent the mythical Mount Horai. A wooden bridge leads to an island representing a crane, and a stone bridge connects this island to another representing a tortoise, which is connected by an earth-covered bridge back to the peninsula. The garden also includes a waterfall at the foot of a wooded hill. One characteristic of the Momoyama period garden visible at Sanbō-in is the close proximity of the buildings to the water.
