RMS Empress of Japan was an ocean liner built in 1929–1930 by Fairfield Shipbuilding & Engineering Company at Govan on the Clyde in Scotland for Canadian Pacific Steamships (CP).

This ship was the second of two CP vessels to be named Empress of Japan[1] – regularly traversed the trans-Pacific route between the west coast of Canada and the Far East until 1942.

[4] The new liner intended for the transpacific service was envisioned at approximately 25,000 gross register tons, 203.05 m (666 ft 2 in) in length and capable of carrying 1173 passengers in four classes.

[6] Empress of Japan carried out her sea trial successfully in May 1930, achieving a top speed of 23 kn (43 km/h; 26 mph); and on 8 June 1930, she was delivered to Vancouver for service on the trans-Pacific route.

Amongst her celebrity passengers were a number of American baseball all-stars, including Babe Ruth, who sailed to Japan for a barnstorming tour in October 1934.

[8] Following the end of World War II, Empress of Scotland was needed to meet the newly developing demands for trans-Atlantic passenger service.

[10] Following her sale to Hamburg Atlantic Line in 1958, the ship was radically rebuilt to meet the expanding market for trans-Atlantic passenger service.
