By 1943, losses of merchant shipping caused the IJN to somewhat reorder its
ship building priorities. The 31 units of the Ukuru Class were designed around
an improved Mikura Class hull. The first unit was laid down in January 1944. The
hull was manufactured in pre-fabricated sections to reduce construction time.
