Project 32
was an deployed by Japan against the United States during World War II. It consisted of a hydrogen-filled paper balloon in diameter, with a payload of four incendiary devices and one high-explosive anti-personnel bomb. The uncontrolled balloons were carried over the Pacific Ocean from Japan to North America by fast, high-altitude air currents, today known as the jet stream, and used a sophisticated sandbag ballast system to maintain their altitude. The bombs were intended to ignite large-scale forest fires and spread panic. Between November 1944 and April 1945, the Imperial Japanese Army launched about 9,300 balloons from sites on coastal Honshu, of which about 300 were found or observed in the U.S., Canada, and Mexico. The bombs were ineffective as fire starters due to damp seasonal conditions, with no forest fires being attributed to the offensive. A U.S. media censorship campaign prevented the Imperial Army from learning of the offensive's results. On May 5, 1945, six ...

Incendiary Balloon
An incendiary balloon (or balloon bomb) is a balloon inflated with a lighter-than-air gas such as hot air, hydrogen, or helium, that has a bomb, incendiary device, or Molotov cocktail attached. The balloon is carried by the prevailing winds to the target area, where it falls or releases its payload. Historical use Early proposals In 1792, Joseph-Michel Montgolfier suggested using balloons for bombing British forces in Toulon.''Military Aircraft, Origins to 1918: An Illustrated History of Their Impact'' Justin D. Murphy, page 161 In 1807, Denmark tried to build a dirigible to bomb British ships blockading Copenhagen. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seaplane
A seaplane is a powered fixed-wing aircraft capable of takeoff, taking off and water landing, landing (alighting) on water.Gunston, "The Cambridge Aerospace Dictionary", 2009. Seaplanes are usually divided into two categories based on their technological characteristics: floatplanes and flying boats; the latter are generally far larger and can carry far more. Seaplanes that can also take off and land on airfields are in a subclass called amphibious aircraft, or amphibians. Seaplanes were sometimes called ''hydroplanes'', but currently this term applies instead to Hydroplane (boat), motor-powered watercraft that use the technique of Planing (boat), hydrodynamic lift to skim the surface of water when running at speed. The use of seaplanes gradually tapered off after World War II, partially because of the investments in airports during the war but mainly because landplanes were less constrained by weather conditions that could result in sea states being too high to operate seaplanes ...

Aneroid Barometer
A barometer is a scientific instrument that is used to measure air pressure in a certain environment. Pressure tendency can forecast short term changes in the weather. Many measurements of air pressure are used within surface weather analysis to help find surface troughs, pressure systems and frontal boundaries. Barometers and pressure altimeters (the most basic and common type of altimeter) are essentially the same instrument, but used for different purposes. An altimeter is intended to be used at different levels matching the corresponding atmospheric pressure to the altitude, while a barometer is kept at the same level and measures subtle pressure changes caused by weather and elements of weather. The average atmospheric pressure on the Earth's surface varies between 940 and 1040 hPa (mbar). The average atmospheric pressure at sea level is 1013 hPa (mbar). Etymology The word ''barometer'' is derived from the Ancient Greek (), meaning "weight", and (), meaning "measur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Japan Meteorological Agency
The Japan Meteorological Agency (JMA; ''気象庁, Kishō-chō'') is a division of the Ministry of Land, Infrastructure, Transport and Tourism dedicated to the Scientific, scientific observation and research of natural phenomena.

Wasaburo Oishi
was a Japanese meteorologist. Born in Tosu, Saga, he is best known for his discovery of the high-altitude air currents now known as the jet stream. He was also an important Esperantist, serving as the second board president of the Japanese Esperanto Institute from 1930 to 1945. Jet stream and Esperanto He wrote the first official report from Japan's Aerological Observatory (written in 1926 and in the auxiliary language of Esperanto). In this report (''Raporto de Aerologia Observatorio de Tateno)'' data was stratified by season and used to produce the mean seasonal wind profiles. The profile for winter gave the first known evidence of the persistent strong westerlies over Japan that would later become known as the jet stream. In an attempt to reach an unresponsive foreign audience, Wasaburo Oishi published nineteen reports between 1926 and 1944, all of them written in Esperanto, in total 1246 pages. Wasaburo Ooishi was not only the director of Japan's Tateno atmospheric observato ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Japanese Submarine I-35
''I-35'' was an Imperial Japanese Navy B1 type submarine. Completed and commissioned in 1942, she served in World War II, operating in the Aleutian Islands campaign and the Battle of Tarawa before she was sunk in November 1943. Construction and commissioning ''I-35'' was laid down on 2 September 1940 by Mitsubishi at Kobe, Japan, with the name ''Submarine No. 143''. Renamed ''I-45'' by the time she was launched on 24 September 1941, she was renamed ''I-35'' on 1 November 1941. She was completed and commissioned on 31 August 1942. Service history Work-ups Upon commissioning, ''I-35'' was attached to the Kure Naval District and proceeded from Kobe to Kure. On 1 September 1942, the Japanese activated the Kure Submarine Flotilla, and that day ''I-35'' and the submarine were assigned to the new flotilla, with ''I-35'' as the flagship of the flotilla's commander, Rear Admiral Tadashige Daigo. replaced her as the flagship on 4 September 1942.

Ryōgoku Kokugikan
, also known as Ryōgoku Sumo Hall or Kokugikan Arena, is the name bestowed to two different indoor sporting arenas located in Tokyo. The first ''Ryōgoku Kokugikan'' opened its doors in 1909 and was located on the premises of the Ekōin temple in Ryōgoku, Tokyo. Although no sumo bouts were held after 1945, following the capitulation of Japan and the requisition of the building by the occupying forces, the building itself remained active until 1983, being notably used by the Nihon University. The second ''Ryōgoku Kokugikan'' is currently located in the Yokoami neighborhood of Sumida next to the Edo-Tokyo Museum. It opened in 1985, following the closure of the Kuramae Kokugikan, and is still in use today. The first Ryōgoku Kokugikan History The growing popularity of Sumo during the Meiji period led to the building of the original Kokugikan in Ryōgoku. Until then, Sumo bouts were performed in temples precincts and depended on the weather. In March 1906, the 22nd Imperial ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Washi
is traditional Japanese paper processed by hand using fibers from the inner bark of the gampi tree, the mitsumata shrub (''Edgeworthia chrysantha''), or the paper mulberry (''kōzo'') bush. ''Washi'' is generally tougher than ordinary paper made from wood pulp, and is used in many traditional arts. Origami, shodō, and ukiyo-e were all produced using ''washi''. ''Washi'' was also used to make various everyday goods like clothes, household goods, and toys, as well as vestments and ritual objects for Shinto priests and statues of Buddha. It was even used to make wreaths that were given to winners in the 1998 Winter Paralympics. ''Washi'' is also used to repair historically valuable cultural properties, paintings, and books at museums and libraries around the world, such as the Louvre and the Vatican Museums, because of its thinness, pliability, durability over 1000 years due to its low impurities, and high workability to remove it cleanly with moisture.
