Himeji Castle is a hilltop Japanese castle complex located in the city of Himeji, Hyōgo, Japan. The castle is regarded as the finest surviving example of prototypical Japanese castle architecture, comprising a network of 83 buildings with advanced defensive systems from the feudal period. The castle is frequently known as Hakuro-jō or Shirasagi-jō because of its brilliant white exterior and supposed resemblance to a bird taking flight.
