The Tomozuru incident exposed the danger in Chidori's small, heavily armed design. Trials had already revealed a high centre of gravity and a stated excess weight of 92 tons. Bulges were added to Chidori and the rest of the class, but proved insufficient. The attempt to obtain more fighting ships under treaty limits had produced a design whose stability problems remained unresolved.
