1) Did AKASHI have the position of Gunnery Officer? If so, is there any info as to who was assigned the post?
The post of Gunnery Officer existed, but it was vacant from the start to the end.

The organization of the Repair Department is my guess.
Both Engine Repair Branch and Ordinance Repair Branch were controlled by Division Officers.
Ship Repair Branch didn’t have the post of Division Officer, it was controlled by technical (shipbuilding) captains dispatched from Combined Fleet HQ after 1 December 1939.

5) Are there classes or commissioning dates available for the following individuals?
Engineer
ODA Miozo: Special Duty Officer
Surgeon
SAITO Masahisa: 1929
Paymaster
NAKANO Tatsuichi: Pay.2Y1938

Constructor 造船 S.B. Ship Building
NAKAMURA Koshiro: S.B.1912
Engine Constructor 造機 E.M. Engine Manufacture
YAMADA Sadao
Ordnance 造兵 O.M. Ordnance Manufacture
Initially, IJN had 3 branches (each shown with 2 Kanjis)- 造船 S.B. Ship Building, 造機 E.M. Engine Manufacture and 造兵 O.M. Ordnance Manufacture. (Blue alphabets show my English Translations.) These were integrated into 技術 (Tech.) in 1943. Naval Yards had 造船部 Ship Building Department, 造機部 Engine Manufacture Department, and 造兵部 Ordnance Manufacture Department in principle. So I think Akashi had a Ship Repair Branch, an Engine Repair Branch, and an Ordnance Repair Branch according to Naval Yards.
I do have not so much data on S.B., E.M., and O.M.

I have KUMAGAYA Hideo 熊谷秀夫 (33) as KIA on 3 December 1943, with a posthumous promotion to RADM, according to Nishida's "Materials of IJN". However, the Naval Database does not show him as being KIA, and states his highest rank was CAPT. If he was KIA, are the circumstances of his death known? Or did he simply die of natural causes on 3 December 1943, without a posthumous promotion? TIA for any info on this.

Nishida's "Materials of IJN" is wrong. He was KIA and was promoted to RADM.

Oh, I should have said "the Naval Database is wrong".
Unfortunately I don't know the detail.

Understood. I know he was CO of KIRISHIMA MARU from 24 November 1941 - 22 July 1943, and then was CO of 33rd Specially Established Minesweeper Division from 22 June 1943 - until an apparently unknown date. I had him relieved on 1 June 1945 (date of the unit's deactivation), surviving the war, and dying on 10 January 1946. Anyone know the ships assigned to this Minesweeper Division? Perhaps when one was sunk he was using said vessel as division flagship, and was KIA in its sinking.

What I have for him:

Naval Aeronautics Headquarters Organization 海軍航空本部 組織
海軍航空本部 Kaigun Koku Hombu / Naval Aeronautics Headquarters was in charge of naval aviation administration. It was activated on 5 April 1927 as a companion to 海軍艦政本部 Naval Ship Administration Headquarters. The biggest difference between them was that Naval Ship Administration Headquarters designed the ships itself, while the airplane makers designed the airplanes for IJN "under the Naval Aeronautics Headquarters's guidance." As for IJA, there was similar 陸軍航空本部 Rikugun Koku Hombu / Army Aeronautics Headquarters. Airplane makers also designed the airplanes for IJA "under the Army Aeronautics Headquarters's guidance."
