Adjutants
??? – 1 April 1923 – 30 November 1945

(1) I believe the English translation of Kanji 教育 Kyoiku “Training” is more suitable than “Education”. My impression is that "Education" is mainly "Classroom Learning". But "Training" takes up most of the time, actually. Of course, it is just the impression of a non-English speaker.
(2) External office “Headquarters” had stronger independence (authority) than internal office “Bureau”
Ex;
海軍艦政本部 Is English translation Naval Ship Management Headquarters?
海軍航空本部 Is English translation Naval Air Management Headquarters?
水路部 Hydrographic Department: It was not called "本部 headquarters", but it was an external office
(3) The internal organization of Training Bureau was also downgraded from "Department 部" to "Section 課." However, those duties may have been, as you say, 1st Section: General Affairs and 2nd Section: Engineering. I don't know the work of 3rd Section. And “Bureau” didn’t have the position of “Adjutant”.

Below (1) are the rules for Kanji used in the organizational structure of the IJN, the subject of your research. Until now, I have been posting Kanji with explanations if necessary, based on the principle of "the same Kanji has the same English translation" as shown in (2). The same kanji must not have different English translations elsewhere. (1)

I tried. PDF doesn't work, but JPEG seems fine. So I don't think you have anything to worry about. JACAR has had many troubles recently. I will ask JACAR. I think it will recover in the short term.

As I explained, "Bureau 局" was the second highest position after the "ministry 省" "Fuel Yard" was treated as an "外局 Outside Bureau" at best. Therefore, there is no "Bureau 局" below it. So far, I've corrected your "bureau" to "Bu Department" with kanji 部 in various cases. As a researcher of the Japanese Navy, please respect the Japanese Navy's principles that I explained in the previous post.

The Kanji for Powder Yard is 火薬廠. There were several organizations which used the Kanj 廠.
海軍火薬廠
海軍燃料廠
海軍療品廠
海軍衣糧廠
The functions of the above organizations were accumulation, storage and delivery of various materials. US Army called such organization “Depot”. For example, in the Japanese-English dictionary “Japanese military and technical terms” edited by the Joint Intelligence Center Pacific Ocean Areas (JICPOA). I would like to use “Depot”. So the above are;
海軍火薬廠: Naval Powder Depot
海軍燃料廠: Naval Fuel Depot
海軍療品廠: Naval Medical Supplies Depot
海軍衣糧廠: Naval Provisions and Clothing Depot

Below is what I have now.

Why? Hard to understand.

The Japanese-English dictionary “Japanese military and technical terms” edited by the Joint Intelligence Center Pacific Ocean Areas (JICPOA) was edited for assistance in interpreting captured Japanese documents. It translated Kanji 廠 to English
Depot.
See;
https://books.google.co.jp/books/about/ ... edir_esc=y

Today American organization Depot is translated to the Kanji 廠.
For example;
U.S. Army Sagami General Depot → 米国陸軍相模総合補給廠

Do you also translate 海軍航空廠 to Naval Air Yard, not to Naval Air Depot?

To be honest, I was just using the titles that were used on Nishida's "Materials of IJN" site. I had no idea they were incorrect or misleading.

Thanks. It is a great help-.

Among Nishida's "Materials of IJN" site, I was curious about the following English translations.
海軍艦政本部 → Naval Shipping Command
海軍航空本部 → Naval Air Command
They look like operational organizations. It seems that there are people in AHF who actually think so. Actually, they were technical organizations, as shown in the IJN document weiyan referred to.
海軍艦政本部 → Naval Technical Department
海軍航空本部 → Department of Naval Aeronautics
