Kyoto, Japan
Last but not least, see where the practice of hanami (the custom of observing the fragile beauty of flowers) began: Japan. Although you'll find cherry blossoms throughout the country, Kyoto is a good bet. Japan's former Imperial capital is full of prime viewing spots, such as the Philosopher's Path, which follows a canal lined with hundreds of cherry trees, and Maruyama Park, which is famous for its large weeping cherry tree.
