I can't find a lot of material on the subject, but Japanese WWII veterans seem to have been treated with a great deal of respect. Japan's WWII generation viewed fighting in combat as an honorable way to serve their emperor, who prior to the 1945 surrender was viewed as a divinity. As a result, members of this generation would have accorded veterans a great deal of status. An example may be found in Lt. Hiroo Onoda, a Japanese soldier who hid in the Filipino jungles for almost thirty years after the end of the war because he could not accept the possibility of surrender. Lt. Onoda received a triumphant homecoming after surrendering to his superior officers and was hailed as a hero and symbol of wartime patriotism throughout Japan. This may be indicative of national sentiments towards all WWII veterans.
