I don't think only the J1N was very excellent as a night fighter.
Japanese navy's FD-2 radar was low performance, and it was the degree which can rarely detect B-29 ahead of the 3km.
Though an antenna was being equipped in the J1N, there even was planes onto which radar isn't carrying.

Army was experimenting on the latest at Ki-45Kai"Bo" and other types for "Taki" radar loaded, but these has not been completed. The performance of "TaKi" was similar to FD-2.

The Japanese couldn't complete the night fighter which becomes a definitive edition until the end of war.
The army and a navy threw every plane which can catch up to intercept B-29.

The fact of Shelby searching is recorded in "Rikugun Genyou Shisakuki Shouko Meishou Ichiranhyou".
It means "Army Modern Experimental Planes Call Name List" in Japanese language.
All Japanese planes of what equipped to call what name are written in this document.
That was made by the Army aircraft head office on February 25, 1945.

I had my friend investigate it. In 1975, this document was recorded in a document about weapon production and supplement of the army. And that was kept in "Japan National Diet Library" in Tokyo.
It's also kept there today.

A book of Bunrindo of 1990 year edition is written in that referred to that document.
(It's written in P.36)

Major if you have it can you upload it in the internet?

hi major ! your dragon slayer mission don't want to start!

This forum isn't the place where a mission is uploaded for certain.
That was my mistake.　I'm sorry.

That is what historians call a "primary document," and is even better than the Bunrindo book.

We're lucky that it survived US air raids and post-war Japanese destruction of documents.

There's all sorts of good information on World War 2 which is held in national archives and isn't available on the web.
