This article needs attention from an expert in Martial arts. The specific problem is: There is limited information available in English on this style, but there appear to be numerous Japanese sources.(April 2015)
Araki-ryū (荒木流) is a Japanese koryū martial art founded during the Sengoku jidai by Araki Mujinsai Minamoto no Hidenawa (荒木夢仁斎源秀縄). Araki-ryu is a comprehensive system that specializes in the use and application of many traditional Japanese weapons such as spear, glaive, long and short sword, staff, rope, chain and sickle, and torite-kogusoku (grappling in light armor with weapons).
Araki Ryu was founded in the Tensho period, approximately 1573. Its creation is attributed to Araki Mujinsai (or Muninsai) Minamoto no Hidetsuna. Torite-kogusoku techniques are the central focus of the martial tradition. Through an examination of the records of over forty lines of Araki-ryu, almost all emanate from the 2nd generation Mori Kasuminosuke. Araki Ryu spread quite widely throughout Japan: traditionally, upon receiving a teaching license, one established one's own independent dojo or line. Nonetheless, those separate lines maintained the same central set of grappling techniques.
One of the few extant lines is located in Isezaki village in Japan, which started from Komine Bundayu, and his student, Kurihara Iomji Masashige. The Isezaki line has preserved most of the original curriculum. The Isezaki line focuses heavily on the application of its techniques as it was practiced during the 'Warring States' and early Edo periods. This is exemplified by a heavy emphasis on grappling with weaponry. They also have numerous weapon-on-weapon kata, most likely developed through exchanges among the martial traditions of the area, most notably Jikishinkage-ryu and Kiraku-ryu.
One other still extant line specializes in iaido. Although they claim the same founder, there is no resemblance whatsoever in the names of their kata or their actual techniques. A final school, Araki-ryu gunyo-kogusoku has considerable overlap in its kata with the Isezaki line.
The founder: Araki Mujinsai Minamoto no Hidetsuna 荒木夢仁斎源秀縄
In the Honcho Bugei Shoden (pub. 1711-1715 CE), there is a passage that states, "No one knows where Araki Mujinsai is from, and little is known of his deeds, yet his excellent techniques in torite are renowned." Some lines of Araki-ryu speculate that he is from the family of the warlord Araki Murashige, who served as a general under Oda Nobunaga.
Oral tradition of the ryuha asserts that Araki Mujinsai fought in the Chosen no Eki [war with Korea] and received praise from Hideyoshi, from whom he received the title, Nihon Kaizan, literally "Japan’s opener of mountains."
Common to all lines of Araki-ryû that descended through Mori Kasumi is the story which tells of the formation of the school. In Araki-ryû torite saitan no jo, (The rebirth of Araki-ryû), a text allegedly written by Araki Mujinsai, he refers to Fujiwara no Katsumi as the founder of the school. (NOTE: Although there is no definitive proof, there is some historical evidence within the annals of Takenouchi-ryu that Fujiwara Katsumi studied with the founder of Takenouchi-ryu, Takenouchi Hisamori.
In this text, it asserts that Katsumi like so many other founders of martial traditions before and after him, went to a mountain shrine, in Fujiwara's case, Atagoyama Dai Gongen, praying unceasingly [Atogodaiyama is a shrine in Kyoto prefecture under the auspices of a mountain elemental, a tengu commonly referred to as Akiba Gongen. This deity has many other names/aspects. He is also known as: Tarōbō daimyogi (太郎坊) of Mount Atago (Atago daimyogi of Mount Iizuna, and many others. In the syncretic religion of the era, Shinto, Buddhist and Shugendo deities were conflated--in this case, he is also believed to be an avatar (gongen) of Shogun Jizo Bosatsu. In any event, after one hundred days of austerities, Fujiwara became, "enlightened into the mysteries of combat, and from that time forward, it became easy for him to defeat the strongest men throughout Japan." The text continues, however, that, "he became lost in folly, and ceasing to love the art for itself, came only to care about winning. He acquired a filthy name." This of course refers to the hubris which can result from unbridled success coupled with an absence of the moral and ethical center upon which power should be built. Though not explicitly written in this text, it is implicit that he recovered his spirit and honor and became a moral individual. This text is rather unique among martial art origin stories in its recognition of the intoxication of power.
Araki-ryû was maintained in many areas of Japan, but by the 20th century, most lines became extinct. There are three remaining lines in Japan. 1. Two factions of Araki Ryu located in Isezaki, maintained by the sons of, respectively, Kikuchi Genkichi and Suzuki Isematsu. Although they chose to maintain their own dojo and separate administration, they are fundamentally the same. Araki-ryu was designated a cultural treasure of Isezaki in 1967 2. Araki-ryu gunyo-kogusoku, a tradition descending from Araki Buzaemon, quite distinct in many respects from the Isezaki Araki-ryu, but also sharing many elements in common. 3. Araki Mujinsai-ryu iaido - there are several factions of this group which exclusively practices sword drawing. Other than claiming the same founder, there is no apparent relationship in either technique or the names of the kata within the curriculum.
