Takamatsu Castle in Kagawa Prefecture is also known as Tamamo Castle. The castle was built in 1590 by Ikoma Chikamasa, the first feudal lord of the Takamatsu Domain. Fifty-four years later the castle and fief were given to the Matsudaira clan. Being built on the shores of Takamatsu, the castle is well known as one of the three mizujiro (water castles) of Japan. Today, the castle grounds—particularly Sakura no Baba—are famous for cherry tree viewing in spring. There are also port facilities to the north side of the castle. Much of the castle is still visible and it has been declared a National Historic Site.
