Kawasaki Heavy Industries, Ltd. held a ceremony on November 6, marking the launch of the submarine Toryu at its Kobe Works' No.1 Building Berth, which was built for the Japan Ministry of Defense (MOD). The ceremony was attended by a delegation of top MOD officials.

This is the 12th Soryu class submarine, and the 29th built at the Kawasaki Kobe shipyard after World War II.

It provides high water pressure resistance by using high strength steel for its pressure hull, and superior submerged operations and propulsion performance by adopting an X-rudder. It also has lithium ion battery systems for increased underwater endurance, a variety of automated systems, improved surveillance capabilities using high-performance sonar, increased stealth capabilities, and enhanced safety measures.
