旅順港閉塞作戦
In April and May, "Akashi" escorted transports conveying the Japanese Second Army to Manchuria, and escorted destroyer squadrons from Japan to the front-lines. On 15 May, she assisted in the rescue of survivors from the crew of the ill-fated battleships and after those ships struck naval mines off the coast of Port Arthur. She then joined the list of Japanese ships blockading the Russian naval base in the Battle of Port Arthur.
