JS Ishikari (DE-226) was the first destroyer escort with a gas turbine engine and surface-to-surface missiles of the Japanese Maritime Self-Defense Force.
Alternatively she had the OPS-28 surface search and target acquisition radar which could deal with low-altitude aircraft and missiles.
The Ishikari design was equipped with eight Boeing Harpoon surface-to-surface missiles as the key weapon system whereas traditional Japanese frigates were specialized in anti-submarine warfare.
She was commissioned on 28 March 1981, and was deployed at the Ominato District Force (home-ported at Mutsu, Aomori).
It was decided that Ishikari was too small to continue production, so the vessel was succeeded by the Yūbari class two years later.
