It was planned in 1977 as a substitute for the aging laying ship Tsugaru (ARC-481). As with its predecessor, its main task is to install underwater hearing monitoring equipment at bases, ports, strategic sea areas. For the first time, a laying device was installed on the stern to support long-distance laying work.
This made it possible to bury submarine cables in the mud instead of the conventional bare laying, which was easy to cut in the bottom trawling fishery represented by trawling nets. The vessel had sheaves on the bow and stern, and a large cable tank was installed inside the ship, and cables were laid via the cable engine.
Since delicate maneuvering was required during laying work, the propeller is a variable pitch floperer, and the bow and stern were equipped with side thrusters. In addition, the ocean observation equipment was also substantial, equipped with precision sounding, mud sampling, water sampling equipment, thermometer, satellite navigation equipment, Omega navigation, Loran C and other navigation support equipment, and was placed in the central control room to concentrate.
She was retired on 4 April 2012 without waiting for the commissioning of the successor ship Muroto (ARC-483).[2][3] After that, in October 2012, she left Kure base for Dokai Bay, Kitakyushu for dismantling. Parts of her are on display at JMSDF Kure Museum.
