In the Japanese Gardens, there is a Cultural Center, a restaurant , a greenhouse with a nice collection of Bonsai trees and a gift shop.
You can cross the lake by the Divine Bridge, leading to the island where medicinal herbs are grown. The lake is surrounded by traditional plantings and there are carp ( very large Koi) in the lake. There is a Japanese Peace Bell and traditional stone lanterns. A Buddhist Temple is on the grounds and they often host traditional Japanese holidays and events. Kodo drummers and traditional dance are two things that are big favorites.
