Japanese secret and special weapons

From Wikipedia, the free encyclopedia

Plans for the incorporation and development of special or secret weapons by Imperial Japan during World War II , were originally hidden from public knowledge to protect their efficacy. The United States and Germany are more famous for their development of special weapons, but Japan and Russia to a lesser extent both pursued weapons development.

The weapons developed by Japan included advanced conventional weapons, as well as biological and chemical weapons. A diverse cross section of institutions and people in wartime Japan participated in various areas of development, such as The Munitions Ministry (Japan), the Tokyo Imperial University, the Riken (Japanese Institute of Physics and Chemical Research), the Black Dragon Society, the Mitsubishi business conglomerate, and the Nakajima Company. Military units involved were the Kempeitai, First Tachikawa Army Arsenal, Sagami Army Arsenal, and Yokosuka Naval Arsenal.

[edit] Unconfirmed, futuristic achievements

Weaponry supposedly created in conjunction with Germany. The following are undocumented in either Japanese or German historical records.

• Foo-Fighters (Feuerball) artifacts:

These are remote-controlled spheres which are sent against the enemy with supposed electromagnetic effects in aircraft or simple psychological weapons for frightening enemy pilots. Weapon identified as AEG Kugelwaffen sent to Japan via submarine and long-range aircraft technology transfers. Several of the Kugelwaffen are seen trailing Sally bombers with the gunners making no attempt to shoot them down, suggesting they were being tested. Encountered in the Pacific after Germany surrendered, the 20th and 21st BGs reported these weapons in over 300 sightings.

• Disc-shaped or cylindrical air vehicles:

Cylindrical or disc-shaped aircraft with advanced engines that Germany sent to Japan in the last days of the war, again by submarine technology transfer. Type of discs sent supposedly WNF Feuerball type. No Vril or Haunebu Type would fit in any of the German submarines and the Germans were not likely to share any of the occult SS E-IV Technical Branch knowledge as those discs were being moved to S America and Base 211 in Neu Schwabenland, Antarctica from Mar-Apr 1945 for continued postwar development.

• Sonic, wind and ray weapons:

Other strange types of weapons which used sounds, used the wind, or shot energy rays, respectively. They are similar to the WindKanone (Windcannon), Schallkanone (Soundcannon), Donar KSK (Kraftstrahlkanone/Strong Ray Cannon). Germany supposedly sent many plans over these artifacts, but no information exists indicating that any of these were constructed in the last days of the conflict. However, the Captain of U-977 that surrendered in Argentina months after Germany's capitulation revealed in his book, "U-977" that the Japanese delegations sent to Berlin observed the SS death rays (crude microwave weapons) in 1945.

• Supposed Japanese actions joining with Germans in an unknown German base in the Antarctic area. This was Base 211 constructed between 1941-43 in the Muhlig-Hoffman mountains.

"Neu-Schwabenland" underground complex with "Neu Berlin" as capital of surviving Reich led by SS General Hans Kammler. There is ample evidence of construction of this base with German surface raiders and U-boats making continuos journeys to the S Atlantic, Argentina's Tierra del Fuego (Fire Island), and Antarctic waters. The Germans set up meteorological bouys and weather stations from Antarctica all the way up to the Patagonia region of Argentina. Doenitzkept a large number of U-boats in the S Atlantic despite the raging war in the N Atlantic and it was Doenitz who became the second Fuhrer of European Germany, Neu Schwabenland having never surrendered. Both the US and UK established presences in Antarctica during the war and some Germans were captured on the Falkland Islands (Islas Malvinas). Argentina made their Antarctic claim the same year as Base 211 became operational-1943 and aided the Nazis against US and other S American national pressure. In March 1945,the US finally pressured Argentina to declare war on Germany and Japan but to no avail. The Perons sheltered the Nazis and let Odessa ferret war criminals into Argentina postwar. Argentine naval records report unusual disc craft operating off their coast during and after the war, BEFORE the US 1947 UFO sightings began ironically where German weapons were being tested in New Mexico.

• Supposed Japanese-German Space programs.

Supposedly, Germany previously and during the war developed a SS space program (Raumflug), which included specialists from the Japanese Army and Navy. No confirmation of this exists. Other German units implied are the SS E-IV/V which managed Thule and Vril Nazi space programs. Von Braun and Peenemunde were shut out of SS disc and Raumflug develop, their final achievements being the construction of the A-9 and plans for multi-stage rockets, circular space stations, space mirror weapons (of which Hitler inquired of Von Braun throughout the war) and EMW's plans for manned V-2 rockets. Separately, Sanger and Irene Brandt worked on the resurrected Sanger Silbervogel (Silverbird) hypersonic space bomber in Lofer, Austria. A mock-up of that vehicle was under construction when the Allies reached them.

These program having the joining action how next:

• Space vehicles RFZ-5 which it called the Haunebu I (1939) follwed by the Haunebu II (1942)/II Do-Stra (1944) and finally the Haunebu III mothership by 1945.
• Giant "Andromeda-Gerat" cylindrical craft designed for channeled spaceflight were constructed in above-ground abandoned Zeppelin hangars. Two were under construction with one captured by the US Army in 1945 and the other one escaping.
• Supposed Vril channeled spaceflight to Aldebaran in Taurus Constellation 65 light years away departed Germany in March 1945 with planned return in early 21st century. On board were 130 crew and Vril Chefin Maria Orsic who started the entire German space disc program back in 1922 Munich with the Jenseitsflugmaschine.

With respect to this, there exist only some references or memories of any Japanese researchers who supposedly worked in some assignments over these technologies, but no real evidence about these exists.

One of these references is about an ancient technician of the Mitsubishi company who remembers a strange cylindrical or spherical artifact acquired from a German submarine in the last days of the conflict. Theirs poses mission to armed one of these two examples (is very similar at German "Feuerball" objects) and these artifact are very hard to controlled for this decided destroy the second example. The Japanese were highly superstitious and could not conceive of the type of invisible propulsion system that these objects operated by; subsequently they were associated with demons and dynamited in a pit after Japan officially surrendered.

Other references about these weapons are the encounter of a Japanese Navy Mitsubishi A6M Zero with a Disc over Genzan (Chosen) and the reports of B-29 pilots in Marianas and Proper Japan of some Sphere of light (Foo-Fighters) in the last month of the war. Both Nakajima and Mitsubishi are suspected of having tried to construct purely Japanese discs during the war, exemplified by the 1942 "Battle for L.A." disc that was fired upon to no effect. Recent analysis of the photos reveals a disc design different than that of the Germans, same for the 1942 sighting of a strange disc over Hopeh Province in China. These supposed Japanese discs had one thing in common- they were quite slow and tended to fly in a straight flight path. German discs by comparison were running off powerful EMG engines capable of speeds of well over 7,000 km/h and were heat-shielded by a metal called Viktalen. Some call this "Frozen Smoke".

[edit] About unconfirmed, futuristic achievements

This is from some certain sites of Nazi UFO in WW2 and related topics.

• A Bulgarian researcher, Vladimir Terzinsky, investigated the German-Japanese Space program and its connections with Military technical collaboration. For example, he spoke about the Fieseler Fi-103 (V1) and Dornier Do 335 Pfeil and your Japanese developed in Kawanishi Baika suicide pulsejet plane and the Kawanishi J1W1 Shinden interceptor.

• From your sources proceeded the story of a Mitsubishi specialist about a spherical object (similar to the German feuerball) why theirs said why proceeded from German Submarine and poses troubles with these strange artifact. He mentioned inclusive the Japanese connection with Neu-Schwabenland control space center in the Antarctic area.

• Another thinks if why occurred in the Antarctic area one supposed technical exchange of Japanese Sub Type I-400/M6A1 Seiran bombers with the Germans for another military technology that they gave to the Japanese.

For other part the rest of the information are mentioned for historical purposes, but no verification of the reality of these weapons exists.

[edit] Japanese army interests in development of secret weapons

With the reinforcement of the defenses of the homeland, a strong desire arose within IGHQ to improve the military situation by the invention of Special or Secret weapons for decisive combat. In order to apply science to military problems, from every aspect, IGHQ therefore appealed to scholars and technical experts for their co-operation.

Among the various assorted types of such weapons intended for decisive battle, the Japanese Army made efforts to put thermal rays to practical use. They tried to perfect bombs which fall due to the attraction of heat sources, in order to sink American troopships, with a 100% certainty of kill. This was expected to retrieve Japan's fortunes in one fell swoop.

In the middle of 1944, experimentation with these projectiles was carried out near Lake Hamana, in co-operation with many scholars and technicians. Difficult problems appeared in succession, however, requiring resolution, and the bombs could not be put to practical use. Another secret weapons was evaluated with similar results.

Since the war situation was coming to a head before the completion of thermal-ray weapons, IGHQ was obliged to rely upon ramming techniques: suicide ships or "special-attack" planes which could be easily produced in large numbers. Weapons for decisive combat thus came to mean suicidal expedients.

The Japanese Army pinned its hopes on the balloon bomb (ten meters in diameter) as the only weapon for attacking the American Mainland. Ideas concerning these balloon bombs were derived from balloons which were under study in Manchuria for dropping propaganda leaflets on Soviet Union some time before the Pacific War. It was now planned to use small bombs instead of leaflets, and to have them reach the United States by taking advantage of the strong winds (160 to 320 kilometers per hour) which constantly blow from west to east, at an altitude of 9,000 to 10,500 meters.

The balloon bombs were made in Tokyo by girl students at the Yuraku-za Theater and at the Nichigeki Nippon Theater. As a result, "devil's tongue" arum root jelly completely disappeared from town shops.

For about six months after November 1, 1944, the Japanese Army's Special Balloon Regiment daily released balloon bombs (totalling some 9,000), mainly from sites at Otsu in Ibaragi Prefecture. The objective of this action was not to inflict casualties but to make the Americans feel uneasy psychologically because of surprise explosions scattered throughout the United States. Some of the balloons certainly fell in America, but the effects could not be completely confirmed.

At Japanese Army schools the students were not very well trained in science and technology. Infantry remained the backbone of the Japanese Army, as in olden days. Spiritual strength was considered to be the primary element in the acquisition of victory.

With the deterioration in the war situation, there was a growing desire within military circles to perfect miraculously effective weapons.

Nevertheless it became abundantly clear that the low scientific level of the nation could not possibly yield elaborate weapons. Thus, during the course of the war, the gap between the Japanese and the American scientific potential for national defense grew ever wider with the passage of time.

Weaknesses in national science were certainly a major factor in Japan's loss of the war, but poorness and neglect of science were not attributable to the Japanese Army alone. It may well have been because the Japanese adopted principles of makeshift expediency ever since the Meiji era.

The Japanese Army's attitude toward technology incurred many kinds of great criticism from private sources at the time, the major points being the following:

• The Japanese Army keeps matters tightly secret

• The Japanese Army has a great predilection for bamboo-spear tactics, and has little understanding of technology.

• Owing to a plethora of research facilities, there is no clear definition of individual responsibility.

• The right technical experts are not assigned to the right posts, since the Japanese Army's own technicians are put in charge of the units; etc.

The American press blackout rendered it difficult for the Japanese to assess the effectiveness of the 9,000 incendiary balloons which were launched on eastward winds. Physical destruction effected by those balloons which did reach the North American Continent actually amounted to "a few grass fires and the death of six people."

The Japanese themselves used the code name "Fu-go" for the balloon operation. Almost fifteen years later, in January 1958, Dr.Lincoln La Paz, Director of the New Mexico University Institute of Meteoritics, and one of the world's outstanding sky-watchers, discussed the luminous phenomena he had observed for 40 years.

Almost everyone scoffed when ranchers and farmers reported seeing bright stationary fireballs in the skies over the western half of the United States in late 1944 and early 1945.

It was not until we captured hydrogen-filled Japanese paper balloons with a large wad of magnesium flash powder cemented to the envelope that we realized these eyewitnesses had been accurately reporting self-destroying, man-made objects.
