This building paper model is the Himeji Castle, a hilltop Japanese castle complex located in Himeji, in Hyōgo Prefecture, Japan. The papercraft was created by Gakken Kids. There is another Himeji Castle papercraft on the site: Canon Papercraft:Architecture/Building Paper Model - Himeji Castle.
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 ("White Egret Castle") or Shirasagi-jō ("White Heron Castle") because of its brilliant white exterior and supposed resemblance to a bird taking flight.
