Shiten 支点
Japanese for a point of support or fulcrum; in rope, the suspension point, usually a wooden beam, that uplines run to.
Shiten (支点) is a general Japanese word; Jisho.org glosses it as a fulcrum or a supporting element in a structure. Shibari Study translates it as support and uses it for a suspension point, usually a wooden beam. Its glossary also has shikominawa, from shikomi, preparation, and nawa, rope: the rope that fixes an anchor point onto the beam while the space is being prepared, a step it treats as important for safety and for the flow of a scene.
