Metsuke

Metsuke (目付) were the censors or the inspectors of Tokugawa Japan. They were bakufu officials ranking somewhat lower than the bugyō. The metsuke were charged with the special duty of detecting and investigating instances of maladministration, corruption or disaffection anywhere in Japan; and particularly amongst the populace having status below the daimyō.

Intelligence gathering

The shogunate recognized the need for some kind of internal intelligence-gathering apparatus and for some degree of covert espionage within its own ranks. It could be said that the metsuke functioned as the Shogun's intelligence agency or as internal spies, reporting to the officials in Edo on events and situations across the country.

The metsuke were charged with focusing on those ranking below daimyō-status; and their counterparts, the ōmetsuke, were responsible for supervising the activities of officials and members of the daimyō (feudal lords).

Although similarly engaged, the reporting protocols of the metsuke and ōmetsuke differed. The metsuke reported to wakadoshiyori who ranked just below the rōjū. The ōmetsuke reported directly to the four or five rōjū at the top of the shogunate bureaucracy. By design, the intelligence-gathering activities of the metsuke was intended to complement those of the ōmetsuke even though there was no official reporting relationship between the two somewhat independent groups.

Daitō-ryū Aiki-jūjutsu

Daitō-ryū Aiki-jūjutsu (大東流合気柔術), originally called Daitō-ryū Jujutsu (大東流柔術, Daitō-ryū Jūjutsu), is a Japanese martial art that first became widely known in the early 20th century under the headmastership of Takeda Sokaku. Takeda had extensive training in several martial arts (including Kashima Shinden Jikishinkage-ryū and sumo) and referred to the style he taught as "Daitō-ryū" (literally, "Great Eastern School"). Although the school's traditions claim to extend back centuries in Japanese history there are no known extant records regarding the ryū before Takeda. Whether Takeda is regarded as either the restorer or the founder of the art, the known history of Daitō-ryū begins with him. Takeda's best-known student was Morihei Ueshiba, the founder of aikido, and maybe the controversial Choi Yong-sool, founder of hapkido.

History

The origins of Daitō-ryū maintain a supposed lineage extending approximately 900 years, originating with Shinra Saburō Minamoto no Yoshimitsu (新羅 三郎 源 義光, 1045–1127), who was a Minamoto clan samurai and member of the Seiwa Genji (the branch of the Minamoto family descended from the 56th imperial ruler of Japan, Emperor Seiwa). Daitō-ryū takes its name from the mansion that Yoshimitsu lived in as a child, called "Daitō" (大東), in Ōmi Province (modern day Shiga Prefecture). According to legend, Yoshimitsu dissected the corpses of men killed in battle, studying their anatomy for the purpose of learning techniques for joint-locking and vital point striking (kyusho-jitsu).

Total war

Total war is warfare that includes any and all civilian-associated resources and infrastructure as legitimate military targets, and typically involves the use of weapons and tactics that result in significant civilian or other non-combatant casualties, whether collateral damage or not. American-English Dictionary defines "total war" as "war that is unrestricted in terms of the weapons used, the territory or combatants involved, or the objectives pursued, especially one in which the laws of war are disregarded." The term can also be applied when the war effort requires significant sacrifices by most of the friendly civilian population.

In the mid-19th century, scholars identified "total war" as a separate class of warfare. In a total war, to an extent inapplicable to less total conflicts, the differentiation between combatants and non-combatants diminishes and even sometimes vanishes entirely as opposing sides can consider nearly every human resource, even that of non-combatants, as nevertheless part of the war effort.
