The term 'National Capital' can refer to two different cities: Roma, the capital of Italy, and EDO, the former name of Tokyo, Japan. Roma is a city with a long history, having been founded in 753 BC. It is home to many iconic landmarks, such as the Colosseum and the Pantheon. EDO was the capital of Japan from 1603 to 1868, and was renamed Tokyo in 1868. It is now one of the largest cities in the world, and is known for its modern architecture and vibrant culture.
