Mitsumasa Yonai
She was used to transport Japanese soldiers and supplies to Siberia in 1922 as part of Japan's Siberian Intervention. During the time, "Kasuga" was commanded by Mitsumasa Yonai, another future Prime Minister of Japan. On 15 June 1926, the ship helped to rescue the crew of the freighter that struck a rock off the coast of Japan and broke up. Two of her crewmen were later awarded silver medals for gallantry during the rescue by King George V.
