This incident forced the IJN to review the stability of all recently completed, under construction and planned ships.
After the launch of the lead ship, its high centre of gravity - even higher than feared - had been noted and efforts made to remedy this.
High-speed sea trials showed it to be unstable, however, and further efforts were made to rectify the problem by adding bulges to the hull.
At the time of its loss, Tomozuru was low on consumables such as fuel or water that would have ballasted it and lowered its centre of gravity.
It was part of the naval support force for the invasion of Netherlands New Guinea in April 1942 and was present in the Banda Straits in July 1942.
