Those who take a stroll through the gardens will be able to discover all the essential components of a Japanese garden: a pond, islands, a waterfall, lanterns, bridges, a tea house and a Zen garden. This green oasis is a rich mix of Japanese tradition and Mediterranean touches, the result of close collaboration between gardeners from Monaco and Japan. The bamboo hedges, tiles (Awaji Island), stone lanterns, and the woods used in the various structures (gate, tea house, etc.) were all imported from Japan, while the plants, all Mediterranean (pine, olive and pomegranate trees), were pruned and looked after by Mr Beppu for three years to give them a Japanese appearance.
