"Nisshin" was the last of the 10 "Giuseppe Garibaldi"-class armored cruisers to be built. The first ship had been completed in 1895 and the class had enjoyed considerable export success, with the base design being gradually improved over the years. The last two ships of the class were ordered on 23 December 1901 by the Royal Italian Navy, and sold in 1902 to the Argentine Navy in response to the order placed to a British shipbuilder by Chile for two second-class battleships. The possibility of war between Argentina and Chile, however, abated before the vessel was completed, and a combination of financial problems and British pressure forced Argentina to dispose of "Mariano Moreno" and her sister ship "Bernardino Rivadavia". The Argentine government attempted to sell the ships to Russia, but negotiations failed over the price demanded by the Argentinians. The Japanese government quickly stepped in and purchased them due to increasing tensions with Russia despite the high price of ¥14,937,390 (£1,530,000) for the two sisters. Already planning to attack Russia, the government delayed their surprise attack on Port Arthur that began the Russo-Japanese War until the ships had left Singapore and could not be delayed or interned by any foreign power.
