Ship project history


The first protected cruisers built for the Japanese Navy, they were to an improved Esmeralda design prepared by Sir William White. They were completed with a cellular double bottom as an added protection against underwater damage from mine or grounding. The space could be flooded to adjust trim for the operation of the guns. Armour protection was much stronger than in Esmeralda and increased freeboard enabled the designer to arrange for the armoured deck to be placed above the waterline. Further protection was afforded by using the wing passages above and below the armoured deck abreast the machinery spaces as coal bunkers.

The armament was similar to Emeralda's with the 25t 26cm Krupp guns having a 240° arc of fire forward and aft about the keel line. Three 15cm/35 Krupp guns were mounted to port and starboard amidships, each commanding a field of fire of 130°.

Ship protection


Protected deck consisted of two layers and had 51mm flat and 76mm slopes. Engine glacises also were 76mm-thick.

Naval service


Both ships served with distinction at the Battle of the Yalu and during the Russo-Japanese war. They were relegated to minor duties in 1907. Naniwa was wrecked off Uruppa Island, in the Kuriles, 26/7/1912. Takachiho was used as a minelayer since 1907 and was torpedoed and sunk by the German torpedo boat S90 while taking part in the attack on Tsing Tao 17/10/1914.
