Kayaba Ka-1
The Kayaba Ka-1 and Ka-2 were Japanese autogyros, seeing service during World War II for artillery spotting. Design and development The Imperial Japanese Army (IJA) developed the Ka-1 autogyro for reconnaissance, artillery-spotting, and anti-submarine uses. The Ka-1 was based on an American design, the Kellett KD-1A, which had been imported to Japan in 1939, but which was damaged beyond repair shortly after arrival. Kayaba Industry was tasked by the IJA to develop a similar machine, and the first prototype was flying on 26 May 1941. The craft was initially developed for use as an observation platform and for artillery spotting duties. The IJA liked the craft's short, () take-off run, and its low maintenance requirements. Production began in 1941 and the first autogyros were assigned to artillery units for artillery spotting, crewed by pilot and spotter. The prototype Ka-Go was a repaired Kellett KD-1A powered by a Argus As 10c. It went into production as the Ka-1 and about 20 ...

Iki Island
, or the , is an archipelago in the Tsushima Strait, which is administered as the city of Iki in Nagasaki Prefecture, Japan. The islands have a total area of with a total population of 28,008. Only four (4) of the twenty-three (23) named islands are permanently inhabited. Together with the neighboring islands of Tsushima, they are collectively within the borders of the Iki–Tsushima Quasi-National Park. Geology The Iki Islands are volcanic in origin: they are the exposed and eroded basaltic summit of a massive Quaternary stratovolcano last active over 400,000 years ago. Iki Island is slightly oval in shape, and measures approximately from north-south and from east-west. The highest elevation is , a weakly curved peak with a highest elevation at above sea level. The average height of the land surface is 100 meters above sea level. The archipelago is approximately north-northeast of the Kyushu coast at its closest point and southeast of the Tsushima Islands.

World War II Japanese Aircraft
In its most general sense, the term "world" refers to the totality of entities, to the whole of reality or to everything that is. The nature of the world has been conceptualized differently in different fields. Some conceptions see the world as unique while others talk of a "plurality of worlds". Some treat the world as one simple object while others analyze the world as a complex made up of many parts. In '' scientific cosmology'' the world or universe is commonly defined as " e totality of all space and time; all that is, has been, and will be". '' Theories of modality'', on the other hand, talk of possible worlds as complete and consistent ways how things could have been. ''Phenomenology'', starting from the horizon of co-given objects present in the periphery of every experience, defines the world as the biggest horizon or the "horizon of all horizons". In ''philosophy of mind'', the world is commonly contrasted with the mind as that which is represented by the mind. ''T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1940s Japanese Military Reconnaissance Aircraft
Year 194 ( CXCIV) was a common year starting on Tuesday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Septimius and Septimius (or, less frequently, year 947 ''Ab urbe condita''). The denomination 194 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years. Events By place Roman Empire * Emperor Septimius Severus and Decimus Clodius Septimius Albinus Caesar become Roman Consuls. * Battle of Issus: Septimius Severus marches with his army (12 legions) to Cilicia, and defeats Pescennius Niger, Roman governor of Syria.

Depth-charge
A depth charge is an anti-submarine warfare (ASW) weapon. It is intended to destroy a submarine by being dropped into the water nearby and detonating, subjecting the target to a powerful and destructive hydraulic shock. Most depth charges use high explosive charges and a fuze set to detonate the charge, typically at a specific depth. Depth charges can be dropped by ships, patrol aircraft, and helicopters. Depth charges were developed during World War I, and were one of the first viable methods of attacking a submarine underwater. They were widely used in World War I and World War II, and remained part of the anti-submarine arsenals of many navies during the Cold War, during which they were supplemented, and later largely replaced, by anti-submarine homing torpedoes. A depth charge fitted with a nuclear warhead is also known as a "nuclear depth bomb". These were designed to be dropped from a patrol plane or deployed by an anti-submarine missile from a surface ship, or another ...

Sea Of Japan
The Sea of Japan is the marginal sea between the Japanese archipelago, Sakhalin, the Korean Peninsula, and the mainland of the Russian Far East. The Japanese archipelago separates the sea from the Pacific Ocean. Like the Mediterranean Sea, it has almost no tides due to its nearly complete enclosure from the Pacific Ocean. This isolation also affects faunal diversity and salinity, both of which are lower than in the open ocean. The sea has no large islands, bays or capes. Its water balance is mostly determined by the inflow and outflow through the straits connecting it to the neighboring seas and the Pacific Ocean. Few rivers discharge into the sea and their total contribution to the water exchange is within 1%. The seawater has an elevated concentration of dissolved oxygen that results in high biological productivity. Therefore, fishing is the dominant economic activity in the region. The intensity of shipments across the sea has been moderate owing to political issues, bu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Noto Peninsula
The Noto Peninsula (能登半島, ''Noto-hantō'') is a peninsula that projects north into the Sea of Japan from the coast of Ishikawa Prefecture in central Honshū, the main island of Japan. The main industries of the peninsula are agriculture, fisheries, and tourism. Name According to Alexander Vovin, the name is derived from Ainu 'cape' or 'big cape'. It is written with two ''ateji'' (''ad hoc'' kanji used for an unrelated word): 能 ''nō'' 'ability' and 登 ''tō/to'' 'ascend'.

Tsushima Island
is an island of the Japanese archipelago situated in-between the Tsushima Strait and Korea Strait, approximately halfway between Kyushu and the Korean Peninsula. The main island of Tsushima, once a single island, was divided into two in 1671 by the Ōfunakoshiseto canal and into three in 1900 by the Manzekiseto canal. These canals were driven through isthmuses in the center of the island, forming "North Tsushima Island" (Kamino-shima) and "South Tsushima Island" (Shimono-shima). Tsushima also incorporates over 100 smaller islands, many tiny. The name ''Tsushima'' generally refers to all the islands of the Tsushima archipelago collectively. Administratively, Tsushima Island is in Nagasaki Prefecture. The island group measures about by and had a population of about 34,000 . The main islands (that is, the "North" and "South" islands, and the thin island that connects them) are the largest coherent satellite island group of Nagasaki Prefecture and the eighth-largest in Japan.

Fukuoka
is the sixth-largest city in Japan, the second-largest port city after Yokohama, and the capital city of Fukuoka Prefecture, Japan. The city is built along the shores of Hakata Bay, and has been a center of international commerce since ancient times. The area has long been considered the gateway to the country, as it is the nearest point among Japan's main islands to the Asian mainland. Although humans occupied the area since the Jomon period, some of the earliest settlers of the Yayoi period arrived in the Fukuoka area. The city rose to prominence during the Yamato period. Because of the cross-cultural exposure, and the relatively great distance from the social and political centers of Kyoto, Osaka, and later, Edo (Tokyo), Fukuoka gained a distinctive local culture and dialect that has persisted to the present. Fukuoka is the most populous city on Kyūshū island, followed by Kitakyushu. It is the largest city and metropolitan area west of Keihanshin. The city was ...
