"Kachidoki Maru" was built in 1920 as Wolverine State, one of seven Design 1095 ships, by the United States Shipping Board at New York Shipbuilding Corporation, Camden, New Jersey. Renamed "President Harrison" in 1922, she was operated by Swayne & Hoyt Lines on a service connecting the United States West Coast to Brazil and Argentina with the Pacific-Argentine-Brazil Line. In 1923, the ship was transferred to the Dollar Steamship Lines and sailed on their "round-the-world passenger service" until 1938. Chartered by the United States Army in December 1941 to evacuate 4th Marines from Shanghai (and carrying the crates with the remainings of the now lost Peking Man), she was beached on the return trip for additional evacuation, but salvaged and repaired by the Japanese, which renamed her "Kakko Maru" and later "Kachidoki Maru".
