Here, you’ll find cherry blossoms in spring and fiery foliage in autumn, while year-round there are teahouses to visit and a succession of scenic viewpoints to enjoy—the most distinctive being from atop the Fuji-shaped Hiraiho Hill, looking out over Ritsurin’s central pond with Mount Shiun serving as borrowed scenery in the distance.
Following the coast southeast from Takamatsu, it’s an hour by train to Tokushima Prefecture, home to the annual Awa Odori dance festival and the deep natural surrounds of the Iya Valley, but also the captivating whirlpools of the Naruto Strait. Up to 22 yards (20 meters) in diameter, these whirlpools are created when the central current merges with slower currents on the sides of the strait, something you can see up close on boat tours or through the glass-bottomed observation deck of the Onaruto Bridge.
