Service record
 Sumida was laid down on 13 April 1939 and launched 30 October 1939 at the Fujinagata Shipyards in Osaka, Japan. On commissioning on 31 May 1940, she was assigned to the Yokosuka Naval District and attached to the 1st China Expeditionary Fleet, arriving in Shanghai on 17 June. From July to November, she was assigned to patrols of the lower Yangtze River, and from November to April 1942, to patrols of the middle Yangtze as far as Hankou. After April 1942, she was assigned to patrols of the upper Yangtze.
