Castle Shirasagi is a location in Fire Emblem Fates.
Castle Shirasagi is the royal castle in Hoshido. It stands atop a sheer-sided mountain surrounded with the Hoshidan capital at its base, and serves as the residence of Queen Mikoto and her step-children Ryoma, Hinoka, Takumi, and Sakura.
Shirasagi is the Japanese word for Pure-white Heron (白鷺, or great egret). It is also the nickname of Himeji Castle, an 83-building complex near Osaka, which earned the nickname because the white plaster walls resembled an egret's or heron's outstretched wings.
Castle Shirasagi inspires the Castle Sol stage in Fire Emblem Warriors, which often hosts missions including Hoshidan characters.
