Awesome...thanks! A few discrepancies:

1) SAKAI TOSHIMI was a LTJG, and remained Navigator until I-1's loss. SAKAMOTO Eiichi was posted CO on 31 October 1942.

2) MUTO Keigo was a line officer (he was CO of RO-64 in early 1945, and was KIA when she was lost). I have an Engineer for I-1 named BUTO Hisao.

3) I have HANABUSA Hiroshi as Navigator was I-7 was lost. Was Communications Officer an additional duty, or did he first serve as Communications Officer before being posted Navigator?

4) Was LCDR Shimizu Kiyonao relieved as Chief Engineer of I-18 or I-19 before their losses? Was he aboard either of them when they were sunk?

5) MINAMIDE Shigeji was appointed Chief Engineer of both I-25 and I-26 on the same date?

6) MATSUURA Shinichi was appointed Chief Engineer of both I-65 and I-74 on the same date?

7) NAKAI Makoto was appointed CO of I-123, not I-63, which was sunk pre-war.

8) I have KATO Seiichi as posted Torpedo Officer of I-17 on 15 October 1942 (and KIA when she was sunk). Was the post aboard I-171 additional duty, or is this a mistake?

9) I have LTJG KUDO Yoshinosuke (66) as the initial Torpedo Officer of I-177. He was assigned there until some time in October 1943.

Hello ijnfleetadmiral,

1) SAKAI TOSHIMI was a LTJG, and remained Navigator until I-1's loss. SAKAMOTO Eiichi was posted CO on 31 October 1942.

Yes, I have pasted SAKAMOTO Eiichi to wrong place.

2) MUTO Keigo was a line officer (he was CO of RO-64 in early 1945, and was KIA when she was lost). I have an Engineer for I-1 named BUTO Hisao.

LT (Eng.) MUTO Keigo was in engineer branch when posted to the Engineer Officer of I-1. Then he was posted to the EO and Engineer Officer of I-37 on 7 January 1943 and 10 March 1943 respectively. At this time his rank was LT. As I posted about “Engineer Officer Problem”, engineer branch had been already integrated into line branch on 1 November 1942. So his rank was changed to LT. Thereafter he was attached to Kure Naval Distinct at the end of May 1944 and posted to the CO of Ro-64 in early 1945, I think. The Kanji of MU-TO is 武(MU)-藤(TO). BU is another pronunciation of 武.

3) I have HANABUSA Hiroshi as Navigator was I-7 was lost. Was Communications Officer an additional duty, or did he first serve as Communications Officer before being posted Navigator?

His first posting was Communications Officer, and the second one was Navigation Officer. The latter was not an additional duty.

4) Was LCDR Shimizu Kiyonao relieved as Chief Engineer of I-18 or I-19 before their losses? Was he aboard either of them when they were sunk?

According to page 27 of JACAR C13072089600, LCDR HASEGAWA Tadashi was appointed on 1 February 1943. He was also appointed the Engineer Officer of I-19 on the same day,.

5) MINAMIDE Shigeji was appointed Chief Engineer of both I-25 and I-26 on the same date?

As for I-26, it was my fault. I would like to withdraw it.

6) MATSUURA Shinichi was appointed Chief Engineer of both I-65 and I-74 on the same date?

I-65 is incorrect. LT KATO Seiji was appointed on the same day.

7) NAKAI Makoto was appointed CO of I-123, not I-63, which was sunk pre-war.

Yes you are correct. I would like to withdraw that.

8) I have KATO Seiichi as posted Torpedo Officer of I-17 on 15 October 1942 (and KIA when she was sunk). Was the post aboard I-171 additional duty, or is this a mistake?

I-171 is mistake. According to page 7 of JACAR C13072087000, LT KATO Seiichi was appointed the Torpedo Officer of I-17 on 28 September 1942.

9) I have LTJG KUDO Yoshinosuke (66) as the initial Torpedo Officer of I-177. He was assigned there until some time in October 1943.

The CO, Navigation, Torpedo and Engineer Officers were appointed on the same day, 26 December 1942. So I believe this is the first posting for I-178.
Usually LT was appointed Torpedo Officer.
I noticed a few mistakes.
As for the Torpedo Officer of I-18, the below is correct.
According to page 5 of JACAR C13072084200, LT TACHIGAMI Rikuta was appointed on 2 February 1942.
As for the Torpedo Officer of I-20, the below is correct.
According to page 5 of JACAR C13072084200, LT NOMURA Shunji was appointed on 2 February 1942.

Thanks for clarifying these! One more question:

1) KATO Seiji was posted Chief Engineer of I-65 on 28 February 1942. Was this double duty with his assignment as Chief Engineer of I-64 from 20 January 1942, or was his career as follows?

Chief Engineer, I-64 - 20 January 1942 - 28 February 1942
Chief Engineer, I-65 - 28 February 1942 - ???

[fontessa]

Hello ijnfleetadmiral,

I am sorry. The information on I-64 was incorrect. According to page 26 of JACAR C13072083900, LT NAKATA Yoshio wa appointed the Engineer Officer of I-64 on 21 January 1942.
