More IJN Officer Info

[fontessa]

Hello ijnfleetadmiral,

1) For SHIRATSUYU, could the following be correct?
Chief Engineers
(E) LT / LT HANADA Shigeyoshi (Eng. 47) - 10 October 1942 - 10 June 1943
LT NARAYAMA Sakae (Spec. Duty) - 10 June 1943 - 15 June 1944

“10 June 1943“ seems to be based on my previous host. But it is incorrect.
LT NARAYAMA Sakae was appointed Engineer Officer before 1 June 1943.
LT HANADA Shigeyoshi was dismissed Engineer Officer and attached to unknown Naval Distinct on maybe the same day. He was appointed HAYANAMI EO on 25 June 1943. (33 C13072091700)
So I checked Jirei Koho day by day basis between 11 October 1942 and 31 May 1943 twice, but couldn’t find HANADA Shigeyoshi.

2)Did NARAYAMA survive SHIRATSUYU's sinking?

Sorry I don’t know.

3) For MOGAMI, was the position of Naimucho absent from 1 December 1943 until her loss on 25 October 1944? I have it being filled by an unknown officer at some point, as this person was listed as being KIA in her final battle. TIA for any info.

MOGAMI KIA List (32 C08030575400)
Commanding Officer CAPT FUJINA Ryo 藤間良 (47)
Executive Officer CAPT HASHIMOTO Uroku 橋本卯六 (50)
Torpedo Officer LT YAMAMOTO Akira 山本明 (66)
Navigation Officer LCDR NAKANO Nobuyuki 中野信行 (59)
Communications Officer LT OKUBO Takeo 大久保武男 (65)

Supply Officer LT SUGIURA Isao 杉浦勲 (Pay.31)
Division Officer LT MURATA Fukumatsu 村田福松 (S.D.Class13)
Division Officer 中尉 TA● Sojiro 田●惣次郎 (S.D.)
MOGAMI’s 599 survivor landed Manila. (1 C14061098700) Most of them were introduced into the ground battle and most of them were KIA.

4) For CHIYODA Naimuchos, I have KUBO Denzaburo as being KIA aboard her on 25 October 1944.

Thanks for the info,

5) For CHIYODA Communications Officers, I now have the following:
(EO) - LT OTAGURO Yasuo (52) – 29 June 1938 - 10 September 1938
LT OTAGURO Yasuo (52) - 10 September 1938 – 14 October 1938
LT / LCDR TAKAGI Toshifumi (52) – 14 October 1938 - 15 December 1938
LCDR SANO Shigeshi (52) - 15 December 1938 - 1 November 1939
LT OKAJIMA Jiro (59) - 1 November 1939 - 1 May 1940
LCDR TAKAHASHI Eiichi (51) - 1 May 1940 - 15 November 1940
VACANT - 15 November 1940 - 25 December 1943
LT ANAZAWA Kimpachi (Spec. Duty) - 25 December 1943 - ???
LT / LCDR* TAKAHASHI Shotaro (Spec. Duty) - ??? - 25 October 1944 (KIA)

Thanks.

6) For AZUSA MARU...awesome! I'm guessing he was a civilian Merchant Captain, as I don't have an officer by that name listed in my Eta Jima Graduates?

I agree. He was a mobilized civilian.
