RMS Empress of Japan, also known as the "Queen of the Pacific", was an ocean liner built in 1890–1891[1] by Naval Construction & Armaments Co, Barrow-in-Furness, England for Canadian Pacific Steamships (CP).[2] This ship – the first of two CP vessels to be named Empress of Japan[3] – regularly traversed the trans-Pacific route between the west coast of Canada and the Far East until 1922.[4] During the First World War she served as armed merchant cruiser, becoming HMS Empress of Japan for the period that she was a commissioned ship of the Royal Navy. Over the course of her career, Empress of Japan traversed 4 million kilometres (2.5 million miles).[5] She made 315 Pacific crossings.[4]
