Situated in Holland Park, the Kyoto Garden is a masterpiece of traditional Japanese landscape design. Opened in 1991, this tranquil space was gifted by the city of Kyoto to commemorate the long-standing friendship between Japan and the United Kingdom.

The plant selection is carefully curated to reflect the changing seasons, from cherry blossoms in spring to the fiery hues of Japanese maples in autumn. Peacocks roam the paths, enhancing the peaceful atmosphere.
