Tamamo Park located near Takamatsu Station and Harbor was originally a site where Takamatsu Castle stood. The castle was built around 1590 by Ikoma Chikamasa, a retainer of Toyotomi Hideyoshi. Later in the Edo period (1603-1868), it was taken over by Matsudaira Yorishige, a famous Mito Komon’s elder brother, and the town of Takamatsu flourished under the rule of the Matsudaira Family.

This seaside castle was popularly known by its nickname of Tamamo-jo (Pearly Seaweed Castle) because it was built to be well-guarded by the sea, which was named “Tamamo no Ura” after “Tamamo-yoshi,” the poetic epithet used by Kakinomoto Hitomaro when he referred to Sanuki province (present-day Kagawa Prefecture).

A lot of events such as the chrysanthemum shows, tea ceremonies and plant fairs are held in the park all through the year. Hiunkaku in the premise is a historic building, which is used for conventions, flower arrangement exhibitions and tea ceremonies.
