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.
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, with an endurance of 7400 nautical miles at 10 knots. 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 Gun Mk I–IVs and four QF 12 pounder 12 cwt naval guns. Tone also had three deck-mounted 457 mm 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 anti-aircraft guns were added just aft of the first smokestack.
Soon after completion, from 1 April 1911 to 12 November 1911, Tone was sent as part of the official Japanese naval delegation to Great Britain, as part of the coronation celebration for King George V together with the cruiser Tsushima.
In World War I, Tone was assigned to the Japanese 2nd Fleet, and fought in the Battle of Tsingtao against the Imperial German Navy. Afterwards, she was re-assigned to the Japanese Third Fleet, and was based out of Singapore, from whence she patrolled the sea lanes in the Indian Ocean and also occasionally in the Dutch East Indies against German commerce raiders and U-boats, as part of Japan's contribution to the Allied war effort under the Anglo-Japanese Alliance .
