A small islet off the coast of the Land of Whirlpools, Hiyuritou literally means, Fire Lily Island. It is the place known to plentifully grow the Fire Lily flower which is native to the Land of Whirlpools but grows most abundantly here. A most celebrated plant, the Fire Lily used in everything from tea to medicine and known for its ability to treat burns (when used in an ointment) and the hallucinogenic effect it has on cats. Cats and people can both travel freely between this island and the main island by way of a land bridge which appears during low tides and stays open for a few hours a day. The Festival of the Fire Lily (also known as the Fire Festival) is held on this island.

There are several small buildings and houses gathered together at the foothills of a high mountain. These are used to house vendors and various other people of importance during the festival (for those who don't wish to travel back to the main island over the weeks the festival is taking place. Beyond this atop a large hill is a pavilion which can house the Sanjikai while they perform their services during the time of the festival. Up higher a mountain is a solitary pagoda which is generally used to house the Fire Cat and Fire Rat during their stay at the festival. Such a place gives them access to the whole of the island and a full view of the beautifully blooming red flowers which are here. During other times of the year, this place can generally be thought of as the home to the Fire Cat and Fire Rat if they choose to live on it, though most like to be more involved with the main island than that.
