Arisaka
The Arisaka rifle ( ja, 有坂銃, Arisaka-jū) is a family of Japanese military bolt-action service rifles, which were produced and used since approximately 1897, when it replaced the Murata rifle (, ) family, until the end of World War II in 1945. The most common models include the Type 38 chambered for the 6.5×50mmSR Type 38 cartridge, and the Type 99 chambered for the 7.7×58mm Type 99 cartridge, which is comparable in power to a modern .308 Winchester round. History The Arisaka rifle was designed by Colonel Arisaka Nariakira (; 1852–1915), who was later promoted to lieutenant general and also received the title of baron from Emperor Meiji, in 1907. Over the course of various wars several productions runs and variants were made, including the transition from the 6.5mm Type 38 cartridge to the larger 7.7mm Type 99, and the introduction of a paratrooper rifle that could be disassembled into two major parts for airborne operations.

Type 38 Rifle
The is a bolt-action service rifle that was used by the Empire of Japan predominantly during the Second Sino-Japanese War and Second World War. The design was adopted by the Imperial Japanese Army in 1905 (the 38th year of the Meiji period, hence "Type 38"). Due to a lack of power in its 6.5×50mmSR Arisaka cartridge, it was partially replaced during the war with the Type 99 rifle, but both rifles saw usage until the end of the war. History and development The Imperial Japanese Army introduced the Type 30 rifle in 1897. However, the weapon had numerous shortcomings, which were highlighted by combat experience in the early stages of the Russo-Japanese War. These included bursting cartridges, a poorly designed lock in which excess gunpowder tended to accumulate, burning the face of the shooter, frequent misfires, jamming, difficulty in cleaning, and cartridge extraction. Major Kijiro Nambu undertook a redesign of the Type 30, which was introduced in 1906. Nambu reduced the number o ...

Type 99 Rifle
The was a bolt-action rifle of the Arisaka design used by the Imperial Japanese Army during World War II. History During the Second Sino-Japanese War in the 1930s, the Japanese soon found that the 7.7mm cartridge being fired by their Type 92 heavy machine gun in China was superior to the 6.5×50mm cartridge of the Type 38 rifle. This necessitated the development of a new weapon to replace the outclassed Type 38, and finally standardize on a single rifle cartridge. The Imperial Japanese Army (IJA) developed the Type 99 based on the Type 38 rifle but with a caliber of 7.7mm. The Type 99 was produced at nine different arsenals. Seven arsenals were located in Japan, with the other two located at Mukden in Manchukuo and Jinsen in Korea. The IJA had intended to completely replace the Type 38 with the Type 99 by the end of the war. However, the outbreak of the Pacific war never allowed the army to completely replace the Type 38 and so the IJA used both rifles extensively during the w ...

Arisaka Nariakira
was a lieutenant general in the Imperial Japanese Army. The inventor of the Arisaka Rifle, he is regarded as one of the leading arms designers in Japanese history, alongside Kijirō Nambu. Biography Arisaka was born in Iwakuni, Suo province (currently part of Yamaguchi prefecture) as the 4th son of a ''samurai'' retainer of Chōshū Domain. At the age of 11, he was adopted by firearms craftsman Arisaka Nagayoshi, from whom he took his family name. After the Meiji Restoration, he enlisted in the fledgling Imperial Japanese Army. In 1891, he caught the attention of General Murata Tsuneyoshi, designer of the Murata Rifle, the standard Japanese Army rifle, and was appointed to a position in the Tokyo Arsenal. In 1897, Arisaka completed work on the Type 30 Rifle, an improvement on the Murata Rifle, which was adopted by the Japanese Army as its standard weapon in time for the Boxer Rebellion.

Polygonal Rifling
Polygonal rifling ( ) is a type of gun barrel rifling where the traditional sharp-edged "lands and grooves" are replaced by less pronounced "hills and valleys", so the barrel bore has a polygonal (usually hexagonal or octagonal) cross-sectional profile. Polygonal riflings with a larger number of edges have shallower corners, which provide a better gas seal in relatively large diameter bores. For instance, in the pre-Gen 5 Glock pistols, octagonal rifling is used in the large diameter .45 ACP bore, which has an 11.23 mm (0.442 in) diameter, since it resembles a circle more closely than the hexagonal rifling used in smaller diameter bores.Barrel History History [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Kijirō Nambu
was a Japanese firearms designer and career officer in the Imperial Japanese Army. He founded the Nambu Arms Manufacturing Company, a major manufacturer of Japanese military firearms during the period. He was awarded the Order of the Sacred Treasure (2nd class) in 1914. Because of his prolific firearms designs, Nambu has been described as the " John Browning of Japan." Biography Nambu was born as the younger son to a former ''samurai'' retainer of the Nabeshima clan, in Saga domain in 1869 (present-day Saga prefecture). His mother died soon after he was born, and as his father had financial difficulties, he was sent out to be raised by a local merchant.

Empire Of Japan
The also known as the Japanese Empire or Imperial Japan, was a historical nation-state and great power that existed from the Meiji Restoration in 1868 until the enactment of the post-World War II 1947 constitution and subsequent formation of modern Japan. It encompassed the Japanese archipelago and several colonies, protectorates, mandates, and other territories. Under the slogans of and following the Boshin War and restoration of power to the Emperor from the Shogun, Japan underwent a period of industrialization and militarization, the Meiji Restoration, which is often regarded as the fastest modernisation of any country to date. All of these aspects contributed to Japan's emergence as a great power and the establishment of a colonial empire following the First Sino-Japanese War, the Boxer Rebellion, the Russo-Japanese War, and World War I. Economic and political turmoil in the 1920s, including the Great Depression, led to the rise of militarism, nationa ...

Bolt Action
Bolt-action is a type of manual firearm action that is operated by ''directly'' manipulating the bolt via a bolt handle, which is most commonly placed on the right-hand side of the weapon (as most users are right-handed). Most bolt-action firearms use a rotating bolt design, where the handle must first be rotated upward to unlock the bolt from the receiver, then pulled back to open the breech and allowing any spent cartridge case to be extracted and ejected. This also cocks the striker within the bolt (either on opening or closing of the bolt depending on the gun design) and engages it against the sear. When the bolt is returned to the forward position, a new cartridge (if available) is pushed out of the magazine and into the barrel chamber, and finally the breech is closed tight by rotating the handle down so the bolt head relocks on the receiver. Bolt-action firearms are generally repeating firearms, but some single-shot breechloaders also use bolt-action design as ...

Ersatz
An ersatz good () is a substitute good, especially one that is considered inferior to the good it replaces. It has particular connotations of wartime usage. Etymology ''Ersatz'' is a German word literally meaning ''substitute'' or ''replacement''. Although it is used as an adjective in English, it is a noun in German. In German orthography noun phrases formed are usually represented as a single word, forming compound nouns such as ''Ersatzteile'' ("spare parts") or ''Ersatzspieler'' ("substitute player"). While ''ersatz'' in English generally means that the substitution is of unsatisfactory or inferior quality compared with the "real thing", in German, there is no such implication: e.g., ''Ersatzteile'' 'spare parts' is a technical expression without any implication about quality, whereas ''Kaffeeersatz'' 'coffee substitute' is not made from coffee beans, and is thus inferior. The term for inferior substitute in German would be ''Surrogat'', which is cognate to English word "surr ...

Imperial Japanese Army
The was the official ground-based armed force of the Empire of Japan from 1868 to 1945. It was controlled by the Imperial Japanese Army General Staff Office and the Ministry of the Army, both of which were nominally subordinate to the Emperor of Japan as supreme commander of the army and the Imperial Japanese Navy. Later an Inspectorate General of Aviation became the third agency with oversight of the army. During wartime or national emergencies, the nominal command functions of the emperor would be centralized in an Imperial General Headquarters (IGHQ), an ad hoc body consisting of the chief and vice chief of the Army General Staff, the Minister of the Army, the chief and vice chief of the Naval General Staff, the Inspector General of Aviation, and the Inspector General of Military Training. History Origins (1868–1871) In the mid-19th century, Japan had no unified national army and the country was made up of feudal domains (''han'') with the Tokugawa shogunate (''bakufu ...

Imperial Japanese Navy
The Imperial Japanese Navy (IJN; Kyūjitai: Shinjitai: ' 'Navy of the Greater Japanese Empire', or ''Nippon Kaigun'', 'Japanese Navy') was the navy of the Empire of Japan from 1868 to 1945, when it was dissolved following Japan's surrender in World War II. The Japan Maritime Self-Defense Force (JMSDF) was formed between 1952–1954 after the dissolution of the IJN. The Imperial Japanese Navy was the third largest navy in the world by 1920, behind the Royal Navy and the United States Navy (USN). It was supported by the Imperial Japanese Navy Air Service for aircraft and airstrike operation from the fleet. It was the primary opponent of the Western Allies in the Pacific War. The origins of the Imperial Japanese Navy go back to early interactions with nations on the Asian continent, beginning in the early medieval period and reaching a peak of activity during the 16th and 17th centuries at a time of cultural exchange with European powers during the Age of Discovery.
