The meticulously landscaped 6.5 acres, built in the early 1960s, are modeled after Korakuen Garden in Okayama, Japan, San Jose's sister city. Paths wind past stone lanterns, a small pagoda and a variety of flora, including flowering cherry trees and carefully placed conifers. On the upper level, a large pool-populated by brightly colored koi, turtles, ducks and blue herons-is spanned by a lovely Moon Bridge. A waterfall pours over ornamental rocks into a lower pool, site of a teahouse. The shapes of the two ponds resemble the Japanese characters for kokoro, a word designating heart and soul.
