Tokyo is home to several immaculately kept and beautifully landscaped gardens. These are owned and maintained by the district wards, and each charge an entrance fee of a couple of hundred yen. Shinjuku Gyoen National Garden is the largest and most famous, but gardens like Koishikawa Korakuen and Rikugien make up for in beauty what they lack in size. These gardens are separate to the parks of the capital, which are free to use and less restrictive on what you can do inside the park (e.g. drinking alcohol and cycling is allowed).
One of the most famous gardens in central Tokyo covering an area of almost 60 hectares. It opened to the public in 1949 and today is home to three gardens (traditional Japanese, French formal, English landscape) and a rock-landscaped greenhouse.
