Takamatsu is home to Japan's largest garden, Ritsurin-koen, which sits at the foot of Mount Shuin. During the Edo period feudal lords spent 100 years constructing the 750,000m2 strolling garden which is designed to provide viewing enjoyment in all seasons.

Ritsurin-koen is a fine example of landscaping, borrowing the pine-clad scenery of Shuin-zan and blending chestnut trees, lotus ponds, arching red bridges and artificial islands. Several elegant tatami teahouses sit in the garden and the entrance ticket allows visitors to take part in a tea ceremony at the Chrysanthemum Moon Pavilion.

There are several interesting museums in Takamatsu including the Sanuki Folkcraft Museum and a sculpture garden designed by Isamu Noguchi. Also of interest are the plateau of Yashima, an ancient battle ground with views of the Inland Sea and nearby Shikoku-Mura, a collection of traditional houses displaying Shikoku architecture and construction techniques.
