Shitai is the Japanese word for cadaver or corpse. It is also used to mean body, although there are a number of other words with this meaning. It is also sometimes used to refer a task force or a human figure.
Many works of Japanese manga and computer games have characters named Shitai or Shitai-san (Mr. Corpse). These characters are generally corpses, and may be involved in rather unsavory activities. You have been warned.
Shitai County is county in Anhui Province of the People's Republic of China.
