Created in the mid-17th century, the garden was originally part of the sprawling villa of the ruling Hosokawa family. An undulating hummock of lush green grass representing Japan—there's even a Fuji-san-like cone in about the right place—is beside a pond surrounded by a network of stone bridges. The garden is dotted with impeccably trimmed bushes and trees. A tiny old teahouse gives welcome respite from the sun's glare. Also on the grounds is Izumi Jinja (Izumi Shrine),
which houses the tombs of several eminent Hosokawa clan members. To get to the garden, take Streetcar 2 or 3 east from the castle to the Suizen-ji Joju-en-mae stop.
