Authorís Note:
[1] Also known as AWAGAWA MARU.

[2] Reports of AWAKAWA MARU's movements on 17 Nov '44 are varied and unclear. One Japanese source claims AWAKAWA MARU suffered medium damaged by torpedo attack on 17 Nov '44 at 33-31N, 124-40E (40 nautical miles W of Shokokusan To (So-Huksan-Do), SW coast of Korea. However, ULTRA report for attacks against MI-27 do not have any intercepted radio messages that refer to damage to AWAKAWA MARU. It is known that AWAKAWA MARU split off from MI-27 at this time but did not sail to Takao. Thereafter AWAKAWA MARU is reported operating in the northern part of the East China Sea. Another source says that AWAKAWA may have been damaged in a collision with an unidentified ship.

[3] There is no record of AWAKAWA MARU arriving at Takao.
