Locked Room – original Gun Operations Room
This is the original Gun Operations Room. It is locked. Mystery surrounds this locked room which is situated between the Gun Operations Room and the Surrender Conference Room. The locked room is out of bounds to all visitors.
In his novel ‘Mystery of the Battle Box’, author Raymond Han attempts a fictional answer to this mystery by creating characters who enlist the help of the spirits of two World War II soldiers — a British and an Australian — who are trapped eternally in the underground tunnel to find the lost treasure of General Yamashita.
