   The eight guided-missile destroyers of the Asagiri class were laid down between 1985 and 1988, and were commissioned between 1988 and 1991. like the destroyers of the preceding Hatsuyuki class, they are intended primarily for the engagement of surface or sub-surface targets, although the ships do also carry a powerful suite of point-defence systems to defeat incoming missiles or aircraft. The ships primary anti-ship weapon is the Harpoon medium-range anti-ship missile, and their main anti-submarine weapon is the Mk 46 Mod 5 Neartip lightweight homing torpedo delivered either by the ship-launched ASROC rocket, torpedo tubes or by the ships embarked helicopter. When first commissioned, the ships each carried one HSS-2B Sea King helicopter, but these have now been replaced by the SH-60J Seahawk.

   The Asagiri class destroyers suffered from a serious design fault: hot gases form the funnels damaged the electronic systems on the main mast and also gave the ships a very pronounced IR signature. The main mast was therefore heightened and offset to port, the forward funnel was offset to port and the after funnel to starkboard. This was undertaken on the last four as they were completing. These vessels also carry improved electronics including a data link to their helicopter, a system that was later retrofitted to the earlier ships.
