I would suggest that

Shinpachi 's generous response to this request is the best service that you will receive anywhere on the planet. 5 kilos of bacon, or it's equivalent Japanese delicacy is deserved!

For translation try OCRing with https://pomodoro.semlab.io/ and then the translation software of your choice. It is the OCR of choice at the US NARA (Archives).

I do not know if it works with Japanese script but it does with Cyrillic script and Japanese is very common.

if you ever come across the same for the Kasei-23, do let me know! that would pretty much be the cherry on top! I'll probably also be searching about the cabin pressurization method, but that's pretty much one of the last things I need along the 23

The basic structure of the J2M looks almost same as the A6M.

In my last post, "IJA/IJN Aviation Material Standards (Copper for rivets and wires)" was wrong.
It should have been read "IJA/IJN Aviation Material Standards (Steel wires including rivets and tension wires)"

I adore you. thank you so much for that!!! you've been providing me with mindblowingly good info I'll have trouble translating some of it because my japanese friends find reading the thing very hard.. though I'll manage somehow, I'll do it bit by bit.

I think I have literally all I need except Kasei-23 specific info, but I'm surprised by the amount of detail I managed to gather in the first place!

If you are in a hurry, Kasei 23 manual is available for JPY5,000(about $60) a copy though I don't guarantee its contents.
Probably a duplicate of original manual.
Just an information for you.
