As part of the 1st Fleet the "Fuji"s participated in fighting off Port Arthur on 9–10 March 1904, wherein "Fuji" sustained light damage and "Yashima" was undamaged. On 15 May "Yashima" struck two naval mines and foundered. "Fuji" participated in the Battle of the Yellow Sea in August and was then slightly damaged during the Battle of Tsushima in May 1905. She was credited with the shot that caused the magazine explosion that destroyed the battleship "Borodino". In October 1908, "Fuji" hosted the American ambassador to Japan and some senior officers of the Great White Fleet, and was later reclassified as a coast defense ship in 1910. The ship was disarmed and converted into an accommodation ship in 1922. "Fuji" was sunk by American aircraft in 1945 and scrapped in 1948.
