Tokyo Station is a major commuter hub that draws throngs of people who visit every day just to admire the Marunouchi side's century-old red-brick and stone facade or stay in its nostalgic hotel. After undergoing a 5½-year renovation, the historic landmark formally reopened on Oct. 1.

The Tokyo Station Marunouchi Building, stretching 335 meters parallel with the train platforms, originally opened in 1914 as a showcase for the nation's ever-expanding rail system. The building suffered heavy destruction in World War II bombing raids and was briefly closed after the war for hasty repairs.

The latest renovation has revived some of the original glory of the sprawling, domed structure, regarded as a central Tokyo architectural masterpiece that bore witness to key historic events over the past century.
