For about 6 days, I did a circuit around the island of Shikoku, and went around to the four main cities of the island, Takamatsu, Matsuyama, Kochi, and Tokushima. Unfortunately, I got caught up in a typhoon whilst in Matsuyama, and had to extend my stay there by another day because of the cancellation of all trains and buses. Other then that though, it was a nice holiday.
The highlights would definitely have to be the food at Hirome Market and the Yosakoi Festival which are both in Kochi. Recommended.
Takamatsu: Udon; Temples in Konpira; Shikoku Village; Ritsurin Park.
Matsuyama: Goshiki somen noodles; Matsuyama Castle; Dogo Onsen.
Kochi: Kochi Castle; Fish balls and Fatty tuna sushi at Hirome Market; Yosakoi Festival.
Tokushima: Naruto whirlpools; Awa Odori Festival.
