Video footage from the time of the incident shows the 178-metre ship swinging its stern right around and straight into the wharf, causing surrounding objects to shake.

The causes of the incident are yet to be determined, although local media indicate poor judgement as key cause.

The warship, homeported in Hiroshima, was the first-ever Japan Maritime Self-Defense Force ship to serve as the primary mission platform for the 2014 Pacific Partnership annual humanitarian and disaster response-focused mission.
