is one of the oldest Japanese schools of swordsmanship (''kenjutsu''). Its primary founder was Kamiizumi Nobutsuna, who called the school Shinkage-ryū. In 1565, Nobutsuna bequeathed the school to his greatest student, Yagyū Munetoshi, who added his own name to the school. Today, the Yagyū Shinkage-ryū remains one of the most renowned schools of Japanese swordsmanship. Its name roughly means ''Yagyū New Shadow School''. == Feudal Japan and birth of the Shinkage school == At the time of its founding by Kamiizumi Nobutsuna, the superiority of a school was determined through duels. Basic postures were distinct; a very low stance was maintained, in the interest of protecting the body. The idea of winning at any price was deeply ingrained in the schools of the time, as were the concepts of ''Isatsu-no-tachi'' (the school of the sword that kills only once) or ''Ichi-no-tachi'' (the sword of only one cut). A great deal of importance was placed on the technology of swords and armor themselves. However, with the arrival of muskets (arquebuses) and other elements of modern warfare, these traditionally invincible techniques were no longer sufficient. Nobutsuna, with the creation of the Shinkage-ryū (New Shadow School), changed basic postures by raising them slightly. He also changed the manner of holding the sword. The swords themselves were changed; in an era in which a sword could be two meters, Nobutsuna shortened the length of the blade. Most importantly, he perfected a new method of teaching to make the study and practice of the Way of the Sword easier. Before Nobutsuna, practice was carried out with either a very hard wooden sword (a ''bokken'') or one with a dulled steel blade. The practitioners had to therefore stop their blows during teaching to avoid hurting themselves or their students. It is claimed that Kamiizumi created the practice sword called the ''fukuro shinai'' (frog bamboo sword), which is made of strips of bamboo similar to a kendo shinai but covered inside a leather pouch. The shinai allowed striking with quickness, fluidity and potency without causing serious or disabling wounds as one would with the wooden sword, and without having to stop the attacks. Nobutsuna, sensing the changes in the ways of war at the time, re-thought his methods of martial arts (''bujutsu''), and began to advocate the utilization of light armour during training. The face of war was being transformed, and as it was necessary to move faster than before. Nobutsuna perfected a style of sword fighting that was freer in its movements, more sparse, more restrained, more adapted to brawls and to duels, than to the fields of large scale battles. Nobutsuna created the ancient schools of sword known as ''satsujin-ken'', or the killing swords. These are characterized by postures and offensive techniques, designed to win at any price. He wanted to establish ''tatsujin-ken''—the sword of an accomplished man, an Expert. The art of the sword of the Shinkage school takes into account and adapts to the opponent's weaponry, contrary to the former sword styles which taught to impose dominance without taking into account the opponent. The strategy of the Shinkage school takes into account the geography of the terrain, the hour of battle, and other parameters. For instance, to utilize the technique named ''empi'', one must understand a deeper, secret level (''gokui'') of battle. In ''empi'', (meaning, the "Swallow takes Flight") one uses a technique of spearing an opponent with a thrown sword. To do this, one learns to use the sword not only to defend his position but to also have the "power of adaptability" in facing different individuals, much as a captain must consider the winds and change sails in order to travel in the best direction to reach his objective. It is similar to a hunting hawk, which must constantly reconsider the best trajectory in which to strike effectively. Like the raptor, it is necessary to be able to anticipate, to be able to assess and definitively act. "Move with the mind, in order to move with the body" is one of the central tenets of the school. Another sword style is called ''Katsujin-ken'' (the One who preserves Life, the Sword of the Victor). ''Katsujin-ken'' teaches that, if one's sword does not stop the movement of the enemy, then one may try to fit to the ''opponent's'' rhythm, thus entering into the mind of the adversary to find his weakness. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Yagyū Shinkage-ryū」の詳細全文を読む スポンサード リンク
