Their DDs were ASW capable, their principal failing was in escorting merchants (not utilizing convoys).

Note, of course, that no Navy would be providing much in the way of ASW capability above the speed where their hydrophones worked until after the fact except via ASW air patrols, or later, surface-search radar.

At 11+ knots, IJN ASW would be blind, anyway, in other words.
