Datotsu refers to a technique in Kendo (Japanese art of fencing.)
It consists of four types: men, kote, do, and tsuki.
Men is a type of datotsu to strike a head with a bamboo sword, and is the most basic one. Generally, shomen-uchi strike is used for striking the upper part of the head, while sayu-men is also used to strike the right or left side of the men by 45 degrees. It is often used for kirikaeshi (a practice method of having a shomen-uchi strike and a sayu-men strike one after the other continuously) or suburi practice strokes.
Kote is a type of datotsu to strike a wrist of a partner.
It is a type of datotsu to strike a part of the trunk of a partner's body. Migi-do (strike on the right side of the trunk of the body) is used in most cases in principle. However, a defense way referred to as midokoro-kakushi (or midokoro-yoke) to guard the men, kote and migi-do was widespread for a period of time, and thus hidari-do has also been used. The hidari-do has been used even after it became considered to be a foul for behavior with no fighting spirit.
It is a type of dadotsu to point out a throat of a partner. Although a tsukidare of men-mask, a guard mask of kendo swordmanship, protects the throat, the tsuki is prohibited for junior high school students and younger because it is dangerous if they remove the mask.
