And still to be mentioned is the food.
Takamatsu and the area around it has to be one of the cheapest (and most satisfying) places in Japan to embark on a gastronomic tour.
The grand speciality is sanuki udon.

There's a movie based in the area that does for udon what Tampopo does for ramen.
it's called Udon - from 2006. It's in numerous formats over the web
(Edited due to warning given below ^)

You can pick up an udon map for free at the Takamatsu Tourist Information centre.
