Nisshin (日進), also transliterated as Nissin, was a Kasuga-class armored cruiser of the Imperial Japanese Navy, built in the first decade of the 20th century by Gio. Ansaldo & C., Sestri Ponente, Italy, where the type was known as the Giuseppe Garibaldi class. The ship was originally ordered by the Royal Italian Navy in 1901 as San Rocco and sold the next year to the Argentine Navy who renamed her Mariano Moreno during the Argentine–Chilean naval arms race, but the lessening of tensions with Chile and financial pressures caused the Argentinians to sell her before delivery. At that time tensions between the Empire of Japan and the Russian Empire were rising, and the ship was offered to both sides before she was purchased by the Japanese.
