Authors' Notes:
[1] Not to be confused with Army transport No. 529 (312-GRT, ’34), Army transport No. 1037 (575-GRT, ’42) or Navy requisitioned ship (B-AK) (2,880-GRT, ’44).
[2] NRT is a ship's cargo volume capacity expressed in "register tons", one of which equals to a volume of 100 cubic feet (2.83 m3). It is calculated by subtracting non-revenue-earning spaces i.e. spaces not available for carrying cargo, for example engine rooms, fuel tanks and crew quarters, from the ship's gross register tonnage (GRT). Net register tonnage (NRT) is not a measure of the weight of the ship or its cargo, and should not be confused with terms such as deadweight tonnage or displacement.
[3] LISBON MARU was refloated 24 Mar ’42, towed to Hong Kong in May ’42 and later to Singapore where she was fully repaired 15 Sep ’42.
[4] There were two categories of Kyuryosen. (Ko) category with an IJN Captain as supervisor aboard and (Otsu) category without.
