Re: More IJN Officer Info

Post by Berend » 18 Jan 2021 00:33

Watase Tsugio (I don't know if this is correct translation), Japanese name 渡瀬次男, survived the sinking of the destroyer Yuzuki. He was KIA on 26 February 1945 on land defending Manila. He was stationed on destroyer Yuzuki in June 1944 and may have been an officer but i'm not sure. Does anyone know what his rank was and which other ships he served on?

Regards,

Berend.

If he was an officer, he was not a Naval Academy graduate. The only WATASE that graduated from the Naval Academy was WATASE Jinni, who graduated 6th of 148 Midshipman in the 39th Class. He was dismissed from the IJN for reasons unknown on 1 April 1913.

There is some info on him from a Japanese article. The photos show he was a petty officer, but eventually he became an ensign, so he was what was called "tokumu shikan" or special duty officer. Special duty officers were treated differently, their information is not recorded on the Kaigun Jirei Koho and a large chunk of their records are suspected to be lost.
