Wrapping The Mysterious Castle, Zen Garden offers a prime location from which visitors can wholly admire the natural heritage city. Inspired by Okayama Korakuen Zen Garden that famously hosts hundreds of black spruces, Buddhist pines, a koi carp pond, artificial mountains and a replica of Fuji Mount, Zen Garden is elaborately and delicately cared for by Japanese artisans and experts. Such an essentially Japanese atmosphere drapes all visitors in unutterable serenity on Ba Deo Hill.
