I'd do a DTIC search first (
https://discover.dtic.mil/).
Although not specifically about aircraft, as an example:
A Short Survey of Japanese Radar, Volume ISome other possibilities:
- They're not free, but just for reference the Warbirds and Trains store on eBay has a category with a few of them.
- The website WWII Aircraft Performance has a scan of at least one original, so the webmasters might know where to find more of them.
- Similarly, the website Silver Biplanes has a Japanese Aircraft Materials page from mostly Australian sources.
- Websites devoted to republishing public domain government material such as GovernmentAttic.org (e.g. Technical Intelligence Supplement), Public Intelligence or PublicResource.org sometimes have something.
- You can also sometimes find some materials on the NASA Technical Reports Server as it includes NACA wartime reports as well.
- The Library of Congress might be a source. They have a Summary Technical Report of the National Defense Research Committee, for example.
- Japan's counterpart to the LoC, the National Diet Library has some old microfilmed documents in their Digital Collections. For instance, a Ki-21 manual.
- The Navy Department Library has some, mostly non-aviation, reports.
- The National Air and Space Museum has a Captured German & Japanese Air Technical Documents collection.
- The user "Micdrow" over on WW2Aircraft.net frequently contributes manuals to the technical subforum.
- The guy running the blog Aviation Archives posts a lot of stuff, but it is mostly American.
- The subdomain Hyperwar has many digitized or transcribed materials.
- Although apparently requiring a login now, an archived version of the Manuals & Documents page of the Historic Naval Ships Association has some aviation materials.
- HathiTrust, a collection of several university libraries, was heavily used in the creation of the Vintage Aviation Books and Periodicals thread. The post about Technical Air Intelligence Center documents is particularly relevant.
- Lastly, I'll plug the Aviation Archives page on my personal website, Warbird Philosophy.
I recognize that most of the above is not exactly what you're looking for, but it's what I could come up with at short notice. Maybe some of them might have something or give you some ideas on somewhere else to search. Hope this helps!
