Before World War II, all homes were required to display "Hinomaru" on national holidays. Since the war, the display of the flag of Japan is mostly limited to buildings attached to national and local governments such as city halls; it is rarely seen at private homes or commercial buildings, but some people and companies have advocated displaying the flag on holidays. Although the government of Japan encourages citizens and residents to fly the "Hinomaru" during national holidays, they are not legally required to do so. Since the Emperor's 80th Birthday on December 23, 2002, the Kyushu Railway Company has displayed the "Hinomaru" at 330 stations.
