Authorsí Notes:
[1] The prototype of the 2TE class, the most unreliable and poorly constructed of the Japanese War Program ships. Three types of engine were used on the design, including an older hot bulb diesel type. With poor construction, the ships were plagued with frequent engine breakdowns and other problems. In contrast to the somewhat better 2E cargo design used mainly in Japanese waters, many 2TE tankers were called on to steam to the Philippines, Borneo and Singapore areas.

Ironically, the small size and very poor quality of the design actually meant a much higher survival rate than other wartime designs sent south as the ships spent much of their time laid up in ports awaiting, or undergoing, repairs. Postwar, the poor condition of the ships meant they were rebuilt, often from the mid-hull up, and as effectively new units, often enjoyed long post-war lives, longer than any other design. The last 2TE believed to be still afloat, cargo ship KAH POH (ex-NANSHIN MARU No. 25), was listed in Lloyds Register until at least 2002.

[2] MUROTSU MARU remains a tanker, somewhat unusual, as most such ships are rebuilt as cargo ships.
