Hikawa Maru
Three times "Hikawa Maru" survived being damaged by mines. The first was on 3 October 1942 while entering port at Surabaya, Java. She was repaired in port and departed on 10 October. The second was on 15 July 1944 when a magnetic mine damaged her off the Caroline Islands. She stopped in Davao in the Philippines on 19–26 July where her damage was inspected and on 1 August she reached Yokosuka for repairs. The third was on 17 February 1945 when she was leaving the Port of Singapore. Her stern struck a mine in the Singapore Strait but she returned to port and was repaired. In March and April the Mitsubishi dockyard at Yokohama made further repairs on her, and from 21 June to 4 July she was drydocked at Maizuru.
