Hello blackkite and others I must say this is awesome stuff! didn't know there was so much info about the Z program I know that Kawasaki was also developing a contender to the Nakajima G10N Fugaku.But I was surprised to read that there is such detailed info,I'm glad   that a lot of info  survived the war.
there are even pics of mock-up models of the huge and very powerfull engines then in development for the Zbomber
great work guys!

Recently I got this big book "富嶽(FUGAKU)" ,Author:Maema Takanori(前間孝則),Kodansha Tokyo published in 1991. It has almost 600 pages.
I will read this book and report near future. Z/FUGAKU was a very mysterious plane. Almost all drawings and data were burned out entirely.
Ed's "JAPANESE SECRET PROJECTS EXPERIMENTAL AIRCRAFT OF THE IJA AND IJN 1939-1945" include very impressive colored 3-side view of Fugaku. It's the ultimate Fugaku. It has HA54 engine, not Z-plane.

Maybe this bit of additional info can be usefull..

In August 1944 it was realized that the technology was beyond reach and Nakjima gave up
on the engine and aircraft as it was originally conceived.
The superbomber was scaled down.
A smaller design was to be powered by 6 Nakajima NK 11A engines that could produce 2500hp.
The scaled down Fugaku would have a wingspan of 207ft and a length of 121ft.
(instead of the 237ft span and 144ft length of the former design)

Hi!
"Super large bomber Fugaku(富嶽)'s engine(4)"
The HA54 engine was required high reliability,the design team wanted to perform several basic tests and full scale mock up model construction prior to fix final design. But the schedule was very severe to perform every test and mock up construction that design team planned.
The HA54 development plan in March 1944 was as follows.
1.Machine manufacturing of parts for No1 and No2 engine:March 1944 to September 1944.
2.Assembly of No1 engine:October 1944.
3.Assembly of No2 engine:Nobember 1944.
4.Endurance test finish:February 1945.
5.The first flight of No1 Fugaku:May 1945.
But in July 1944, Nakajima received order to terminate Fugaku project from IJA and IJN after Saipan island fall(1944/07/07),because IJA and IJN concentrated on fighter manufacturing which used for B-29 Interception and KAMIKAZE special attack.
At the time, the HA54 design team already finished the design and prepared all parts drawings.
The materials for crank shaft and crank case already delivered to Nakajima. Machine manufacturing began.
The design team disappointed very much to receive stop order. They wanted to complete HA54 engine very much. 
Chikuhei Nakajima instructed design team that Nakajima Aircraft will crush after WW2.The automobile age will begin.Study hard!!
(same as my mother ;D)
Nakajima Aircraft became Fuji(Fugaku) heavy industries.

I was wondering if the scaledown version of Fugaku was capable of nonstop flying from Japan to the USA and back.
Has this design a greenhouse cockpit or was this design equipped with a conventional design,and could this design carry the Japanese atombomb?
I'm also very curious was there a transport version of this aircraft? It seems logical that Engineers of the Nakajima company were thinking of a huge cargo aircraft that was capable to carry battle tanks and troops to a battle field far away of the Japanese motherland

In his presentation Chikuhei Nakajima mentioned a transport
variant of his "Z' plan bomber but no details were given.
I strongly doubt about a Japanese A-bomb. In my personal opinion
it is as much a blown up myth as the nazi germany bomb was ...

Fugaku planned to use jet stream. Please see the direction of jet stream. Fugaku's mission was as follows.
Take off Japan, fly over Pacific ocean, bomb the United States, fly over Atlantic ocean and land to Germany.
Take off Germany, fly over Soviet union, fly over Japan sea and land to Japan.
Designers of Fugaku always watched a terrestrial globe. To use stream, it was expected that the range of Fugaku increased 20% - 30%.

Fascinating info Blackkite! Thank you.

To be clear - the blue lines on the maps you have posted are the jetstream? Or are they the planned course of Fugaku missions?

Sorry. It's jet stream line. So jet stream act as strong counter wind for German New York bomber when she goes to there.

Chikuhei Nakajima thought that the targets were Pittsburgh and New York.
Some Japanese fiction writer says that the target was Los Alamos,not Los Angeles. ;D

The Japanese were really developing a atom weapon later into the war,so its hard reality not a myth!they experimenting even with a sort of death ray.
and I know one thing for sure if the Japanese were to manage to build a working device,the Fugaku was the ultimate carrier platform for such a weapon

I heard that Japanese theory for A-bomb was not proper.
