The Kanji for him was 矢野次郎, but he was not Supply Officer. He was appointed Crew.
He was a special duty officer.

I checked 15 July 1945 - 27 November 1945 part of Naval Transfer and Promotion Lists twice, but couldn’t find your ???s.
The Naval Transfer and Promotion Lists and 2nd Demobilization Bureau Transfer and Promotion Lists after 15 August 1945:
1) There was no mention of the dismissal of the appointed officer.
2) There was no mention of the appointment of the officer to be dismissed.
There was a great deal of confusion. I think it was because of post-war confusion.

The Kanji for him was 見藤正男. He was a 2 years duty officers and later converted into permanent duty officer. He was commissioned on 1939.

Hello ijnfleetadmiral,

The unit numbers of Submarine Divisions depended on the Naval Distinct to which they belonged.
Allocated unit numbers:
YokosukaNaval Distinct: 1 - 10
Kure Naval Distinct: 11 - 20
Sasebo Naval Distinct: 21 - 30
Maizuru Naval Distinct: 31 - 40

Submarine Division didn’t have the post of Medical Officer and Supply Officer. And Engineer Officer also became vacant in the latter part of the war.

Awesome...thanks! A few questions:

1) Is this correct for SubDiv 1 Chief Engineers?
VACANT - 20 August 1941 - 10 September 1941

2) For SubDivs 1, 2, 3, & 4, would it be reasonable to say the position of Chief Engineer was vacant after 15 January 1942?

3) Is this correct for SubDiv 4 Chief Engineers?
VACANT - 20 September 1927 - 1 December 1927

Awesome...thanks! I would guess that one reason the position was vacant during wartime and the reason that there were no Surgeons and Paymasters assigned to SubDivs is because that would just be more people taking up space in an already-cramped submarine.

Hello ijnfleetadmiral,

I see. I did not know the reason, but you may be right.
The Submarine Squadron Headquarters had the posts of Staff Officers and Engineer Officer, probably because they were on board a submarine tender.

Indeed. Though in the early days of the war some SubRons had their HQs aboard submarines (I-7 and I-8). Despite these being larger boats, it could not have been easy, and space was probably a highly-prized commodity. :lol:

Hello ijnfleetadmiral,

According to Wiki, the composition of 6th Fleet on 10 December 1941 was as the bellow.

KATORI (6th Fleet Flagship)
SubRon1: YASUKUNI Maru, I-9
---- SubDiv1: I-15, I-16, I-17
---- SubDiv2: I-18, I-19, I-20
---- SubDiv3: I-21, I-22, I-23
---- SubDiv4: I-24, I-25, I-26
SubRon2: SUNTOS Maru, I-7, I-10
---- SubDiv7: I-1, I-2, I-3
---- SubDiv8: I-4, I-5, I-6
SubRon3: TAIGEI, I-8
---- SubDiv11: I-75, I-76
---- SubDiv12: I-68, I-69, I-70
---- SubDiv20: I-71, I-72, I-73

I think I-7, I-8, I-9 and I-10 were under the direct command of SubRon HQs. They are large (ie had the post of Communication Officer), but I guess that operation as a flagship was difficult.

Agreed...three of the four were flagships at the start of the war: I-9 (SubRon 1), I-7 (SubRon 2), and I-8 (SubRon 3).

I checked the missions of the submarine units at the start of the war. All the workable submarines of that time had been put into the operation Pearl Harbor Attack. As an aside, I now realize that this operation has not been assigned a code name. For SubRon2 and SubRon3 of which mission was peripheral patrol, the HQ advanced to the Hawaiian waters. On the other hand, SubDiv1, which had three types of missions, stayed the Headquarters in Japan and commanded the whole. In this case the flagship was YASUKUNI Maru. Probably local commanding officers were appointed for each mission. For example CAPT SASAKI Hank who was the commanding officer of 3rd Submarine Division took the command of special attack submersible carry submarines.

According to I-9's TROM, ComSubRon 1 was embarked aboard her during the Pearl Harbor Operation, not tender YASUKUNI MARU.
