Hi
OK, I am Polish (Central Europe), I have thought you are from Russian (it was wrong), :-). Such similar to "Russian" nickname.

In fact there were serveral parts article in Air Enthisiast (in 70-ties) made by Japan, very comprsivea and based on Japan soruces. Most of publication about Japan side are based accoridng this materilas.
Later in the 80-90 the second material, not so good, but also readable, about Chalaachin=Gol was written in Air Ethusiast.
Thirs there was a book about jananis Army Aces edited 3-4 yeas ago in English there are aslo many information (by Grub Stree)
There are aslo some infor in OSPREY Japanise Army Aces abiut this war.

Also go to G. Merlinger side about Japan Aircrafts in WW II (there is nice stories about this topic too, and this is edited in English). I have lost the link but maybe someone have the link to it.

PS
I have also made, quite big material, about exactly this topic produced in Poland in 2002.

PS
I can not say anthing about his book, because I have never heard/see it. If thies is the same author who writes about Bulgarian Air Forces, it is only depends on which sources he had done this last job.
Reading other Bulgarian books made by Nedialkow I think it could be a little stronger as for me (more data, more details, ect).
