they could use the thermal diffusion process to enrich it!!!!!!!!!!

the bomb might not have been as effective, but i am sure they could have easily made one in 2 years.

Nope. Nukes don't work that way. One of the most closely guarded secret was critical mass.

Watched the whole documentary. It was interesting. Don't be misled by the talk of the first team that failed. When it talks about the second team, it describes where the resources came from, where the facilities were built, and how they were systematically destroyed or taken by the Russians. It seems there was even a successful test (after Hiroshima).

Anyone ever consider that Japan was so resource-strapped because they had secretly diverted resources to a refinement project?

No, they were resource strapped and with the oil and metal embargo USA put on them, they figured taking it by force was easier than capitulation.

but the critical mass is just a threshold, so they didn't need to know exactly how much critical mass they needed, they just needed to exceed the required critical mass.

I never said that I agreed or disagreed. I'm just saying that all the "LOL! They didn't have the resources!" comments aren't acknowledging that they may not have had as many resources as they would have had specifically because much was diverted to a project like it.

That video was as much a documentary as Ancient Aliens. Just because it sounds all serious doesn't mean it wasn't made primarily for entertainment for the conspiracy theory nerds.

Not really. The reason Japan went to was was because they had no resources. With the oil and metal embargo, they were down to months of supply.

Are you this fucking stupid in real life or are you trolling?

I'll make this as clear and concise as it has to be.

1. Japan didn't have the ambition, labs nor were they trying to gain it.

2. US asked Japan to surrender and they did apart from the Emperors chair

3. US bombed the living sheit out of ONLY civilians (the definition of terrorism)

4. US agreed to the previous agreement, the Emperor was not removed.

In short, the US just wanted to bomb something to test it on real people, for 20 years to come the US did that to their own population too with experiments that rival the Nazi experiments in cruelty.

No one cares because USA fuck yea!

The uranium oxide was reportedly labeled as "U-235", which may have been a mislabeling of the submarine's name and its exact characteristics remain unknown; some sources believe that it was not weapons-grade material and was intended for use as a catalyst in the production of synthetic methanol to be used for aviation fuel.

This is wrong, because the guy said it asked for uranium, so they could enrich it.

It wasn't and no, the entire story is false.

Japan wasn't even involved in this experiment, the Uranium was transported from Poland to Germany where the scientists were, in Berlin more specifically, it was refined right there and given enough time they would have had a mechanism to set it off, that was the lagger on the mission, Japan had no hand in any of it and were not a part of it in any way.

Rewriting history doesn't change it apart from in the minds of the deranged.

Japan relied on Germany as their master, they were wrong in doing so and they are wrong now relying on US as their master, when the shit hits the fan and China says enough the US will not interfere.

Yeah, I don't know what is/if anything is wrong in the documentary but it seems people here didn't watch it by some of their statements it seems.

General Kawashima was interviewed on a Japanese TV channel in 1983 and confirmed that 2 tons were shipped to japanese territory during WW2. That is the amount which arrived.

Much more was lost with U-boats which never completed their voyages, including 560kg with U-234 and 800kg waiting for I-52 at Lorient in July 1944.

Kawashima was attempting to procure Uranium for the Army NI Project under Dr Yoshio Nishina. The Army project was pretty much a joke and it was the Navy F-Go project which made real progress. JNFC-Nichitsu conducted a huge survey of Korea and Manchuria between March and May 1944 which discovered ten sources of fergussonite ore.

Between March 1944 and the end of the war these ten mines yielded in excess of 500,000 tons of Fergussonite. The Japanese Navy also procured about 7,000kg of Uranium stocks in China at the start of the war.

There was an even more secret project within F-Go called F-NZ. This project had a secret laboratory in mines above Hungnam (called Konan by the Japanese). Hungnam was a huge industrial centre for the Nichitsu fertiliser works. In the industrial process which yielded amonia heavy water was a by-product. The F-go project is supposed to have successfully developed a nuclear reactor during WW2 according to prof Bunsaku Arakatsu, but little is known of it.

F-Go Navy Project
The Imperial Japanese Navy (IJN) decided to create it's own Atomic bomb project in 1943. Known informally as the Kyoto Group, IJN funded a team around the maverick scientist Prof Arakatsu with 600,000 yen in March 1943.

The Imperial Japanese Navy (IJN) project to enrich Uranium 235 was led by rear Admiral Nitta Shigeru. Nitta worked closely during early stages of the project from 1942 to 1944 on isotope separation with Sakae Shimizu . Dr. Shimuzu developed F-Go’s gaseous Uranium centrifuges.
IJN’s centrifuges were developed by a company specialised in precision ship gyros, Hokushine Electric Company with assistance from Tokyo Keiki Electric Co. These were built under contract by heavy engineering firm Sumitomo. Centrifuges were constructed from Rare earth metal alloys and spun at between 100,000 to 150,000 RPM. [9]

This was an impressive speed since even today the best centrifuges only operate at about 50,000 RPM. The measure of efficiency for any centrifuge at enriching Uranium depends upon the speed at which the centrifuge spins. It has been claimed that these centrifuges were never built, but the revolution could not be known without testing of an actual prototype machine. The biggest hurdles for any centrifuge are in creating bearings and rotor drums able to withstand the enormous forces involved. the earliest rotors used aluminium rotors, Subsequently maraging steel construction allowed even higher speeds, but the Japanese used alloys with Rare Earth metals to create exceptionally strong rotor drums. The Nazis developed carbon fibre brushes and may have shared these concepts with Japan.

Prof Arakatsu seated with Dr Kimura standing

Leading nuclear theorists for the Naval A-bomb were Professor Arakatsu Bunsuku, Dr Sugimoto Asao, Dr. Yukawa and Dr. Kobayashi. Heavy water was harvested by two heavy water plants, one in Kyushu and another at Noguchi's JNFC-Nitchitsu Fertiliser factory in Korea. Heavy water was harvested as a by-product of Amonia Production for explosives. Noguchi is now a company known by the name Shoji Kamata. Heavy water was used by F-Go in a nuclear reactor project about which there is little publicly available evidence, except post war claims by Prof. Arakatsu. [10]

It is not known whether Japan's reactor built at Kyoto worked successfully, or managed to breed any Plutonium. All wartime archives are now controlled by the Japanese Government which is under no obligation to disclose them.

An interesting point emerges however that A.H Compton's investigation report for the Manhattan Project notes that Japan made far more progress in the field of developing nuclear energy than Germany did.

There are a number of contradictions. Contraindications too.
The biggest is how long, given evidence of success and information traitorously transferred from the Manhattan project, how long it took the Soviet Union to produce a bomb.
Last I knew they had collected some German scientists in 1945 to help.

Neither the Nazi nor Japanese societies respected the other very much. Both were racist and zenophobic at the time. Extremely.

Neither Japan nor Germany mobilized their economies for total war. Nothing like the USA, British Empire, or Soviet Union.
The Japanese built up their military (military controled the government after all) but no expansion was made of the merchant marine. Yes they made early captures, but never could support itself.

Hitler's time table called for war in 1944 or 1945 at the earliest. They used Panzer I and Panzer II tanks in Poland, Sept 1, 1939.
It took till May 10, 1940 to invade France, and factually the military was still not prepared.
