This article explores the question of whether or not members of the Japanese royal family need passports for international travel. It is revealed that all members, including distant relatives, are required by law to obtain valid passports before travelling outside their home country's borders for any reason whatsoever - including official visits or diplomatic trips on behalf of their nation or its allies abroad. This is due to Japan's Imperial Household Law of 1947 and Nationality Law of 1950. Even Emperor Naruhito must obtain a passport if he wishes to travel abroad.
