Authors' Notes:
[1] The Chinese Maritime Customs Marine Department, headquartered in Shanghai, was responsible for maintenance of lighthouses on the China coast, conservation of various rivers including the Yangtze and coastal patrols against smugglers. The Marine Department also provided pilots in certain ports. Customs’ large fleet was manned by Chinese and foreign nationals.

Various secondary sources also state NANYO (sometimes shown as NANYO MARU) was the ex-British Bangor Class Minesweeper LYEMUN seized while building at Hong Kong. It is believed this vesel or her sister ship LANTAN became GYOSHIN MARU that survived the war. Two other Bangors became IJN minesweepers W-101 and W-102. Several authorative records, including those at NARA and Gakken, list NANYO as ex-TEH HSING and we have made this assumption accordingly.

Special thanks go to Gilbert Casse of France, Gengoro S. Toda of Japan and Erich Muehlthaler of Germany for help with this TROM. Thanks also go to Dr. Higuchi Tatsuhiro of Japan.
