was a ''Fuji''-class pre-dreadnought battleship built for the Imperial Japanese Navy (IJN) in the 1890s. As Japan lacked the industrial capacity to build such warships herself, the ship was designed and built in the United Kingdom. She participated in the early stages of the Russo-Japanese War of 1904–1905, including the Battle of Port Arthur on the second day of the war. She was involved in the subsequent operations until she struck two mines off Port Arthur in May 1904. She did not sink immediately, but capsized while under tow a number of hours later. The Japanese were able to keep her loss a secret from the Russians for over a year so they did not try to take advantage of her loss. ==Description== ''Yashima'' was long overall and had a beam of and a full-load draught of .

These included fourteen 3-pounder guns and ten 2.5-pounder Hotchkiss guns of the same calibre. She was also armed with five 18-inch torpedo tubes. ''Yashima''s waterline armour belt consisted of Harvey armour and was thick. The armour of her gun turrets was six inches thick and her deck was thick.〔 In 1901, the ship exchanged 16 of her 47 mm guns for an equal number of QF 12 pounder 12 cwt〔"Cwt" is the abbreviation for hundredweight, 12 cwt referring to the weight of the gun.〕 guns.
