, frequently shortened simply to hassō and occasionally called hassō-gamae, is one of the five stances in kendo: jōdan, chūdan, gedan, hassō, and waki. It is an offensive stance, named for one's ability to respond to a situation in any direction. Waki and hassō are not commonly used in modern kendo, except in kata.
In hassō-no-kamae, the left foot is forward, and the sword is held pointing upright with the hilt in front of the right shoulder. The blade should slope slightly to the rear. When cutting, the sword is raised above the head, as in jōdan.
Hassō-no-kamae is used by uchidachi in the 4th kendo kata, opposite shidachi's waki-gamae. This posture is also used in Naginata.
It is also used in Kashima Shinden Jikishinkage-ryū's kata.
Hassō is called in Ittō-ryū and Katori Shintō-ryū, in Shinkage-ryū, and occasionally , because of the stance's resemblance to a tree.
In German traditions such as Liechtenauer this is called right vom Tag. It is often translated as "day" or "from the roof".
