The construction of the first ship of the class began in 2011 at an IHI Marine United shipyard in Yokohama, with funding totalling 113.9 billion yen ($1.5 billion) being set aside in the fiscal 2010 budget for this purpose.
The destroyers of this class were initially intended to replace the two ships of the Shirane class, which were originally scheduled to begin decommissioning in FY2014.

The ship, the largest Japanese naval vessel since World War II, was laid down on 27 January 2012 and launched on 6 August 2013.
The ship began sea trials on 29 September 2014.
The ship was commissioned on 25 March 2015.

The ship is as large as a Japanese carrier of Second World War-era.
Izumo is called a destroyer because the Japanese constitution forbids the acquisition of offensive weapons but the vessel allows Japan to project military power well beyond its territorial waters.
