This lovely 150-acre park was once the estate of the powerful Naito family of feudal lords, who were among the most trusted retainers of the Tokugawa shoguns. After World War II, the grounds were finally opened to the public. It's a perfect place for leisurely walks: paths wind past ponds and bridges, artificial hills, thoughtfully placed stone lanterns, and more than 3,000 kinds of plants, shrubs, and trees. There are different gardens in Japanese, French, and English styles, as well as a greenhouse (the nation's first, built in 1885) filled with tropical plants. The best times to visit are April, when 75 different species of cherry trees—some 1,500 trees in all—are in bloom, and the first two weeks of November, during the chrysanthemum exhibition.
