The Isokaze-class destroyers were designed as part of the first phase of the Hachi-hachi Kantai program of the Imperial Japanese Navy. With the commissioning of the new high speed battleships Yamashiro and Ise, escort vessels with equally high speed and blue ocean capabilities were required.
Internally, the engines were replaced with heavy fuel oil-fired steam turbine engines. Two vessels (Amatsukaze and Tokitsukaze) used Brown-Curtis turbine engines, and the other two (Isokaze, Hamakaze) used Parsons turbine engines. Advances in turbine design and construction permitted more reliable operation than previously with the Umikaze. The rated power of 27,000 shp (20,000 kW) gave the vessels a high speed of 34 knots (63 km/h), and a range of 3,360 nautical miles (6,220 km) at 14 knots (26 km/h); however, the engines could not be run continuously at over 7,000 shp (5,200 kW), which still considerably limited performance.
Armament was increased over the previous classes, with four QF 4.7 inch Gun Mk I - IV, pedestal-mounted along the centerline of the vessel, two in front of the smokestacks and two to the stern. The number of torpedoes was increased to three launchers, each with a pair of 533 mm torpedoes. Anti-aircraft protection was provided by four machine guns.
The Isokaze-class destroyers were completed in time to serve in the very final stages of World War I. Tokitsukaze broke in two and sank off of Miyazaki Prefecture, Kyūshū in 1918. It was raised and repaired at the Maizuru Naval Arsenal, and although re-commissioned as a first class destroyer, was used thereafter as a training vessel at the Imperial Japanese Navy Academy at Etajima.
All Isokaze-class ships were retired on April 1, 1936.
