Tone (利根?) was a protected cruiser of the Imperial Japanese Navy. The ship was named after the Tone River in Tokyo.
Tone was designed and built in Japan by the Sasebo Naval Arsenal, under the 1904 Emergency Fleet Replenishment Program to recover from losses to the Japanese navy in the Russo-Japanese War. As funding was limited, the Diet of Japan rejected budgeting for a sister ship or for subsequent construction of the same design.
Although dimensionally similar to the British-built Yoshino, Tone had the raked funnels and clipper bow that would be a feature of future Japanese warships.
Her powerplant consisted of two Mitsubishi vertical 4-cylinder triple-expansion steam engines with 16 Miyabara boilers, driving two screws. The boilers could run on a mixed-mode of coal sprayed with oil, and could drive the ship at a maximum speed of 23 knots (43 km/h; 26 mph), with an endurance of 7,400 nautical miles (13,700 km; 8,500 mi) at 10 knots (19 km/h; 12 mph). Tone was the last ship in the Imperial Japanese Navy to be powered by a reciprocating engine.
Her main armament consisted of two Type 41 6-inch/45 caliber naval guns behind gun shields, and secondary armament was twelve QF 4.7-inch guns and four QF 12 pounder 12 cwt naval guns. Tone also had three deck-mounted 457 mm (18 in) torpedo tubes. However, the foremost of the 4.7-inch secondary guns were located in a cramped location with a very limited field of fire, and were soon removed and not replaced. After World War I, two 76 mm (3 in) anti-aircraft guns were added just aft of the first smokestack.
