Jiin (Temple Grounds, or Secret Mercy)
Original name: Jiin, Ji'in, Shokyo (pine shadow).

Jiin is an interesting kata to perform with a number of twists and turns to tax your centre of gravity, and if you're familiar with Jion, enough close variations to tax your brain also. Kosa uke is a defining technique, and a shuto strike in kiba dachi is introduced.

History

Jiin is a sibling to the other 'temple' katas, Jion and Jitte, and is strongly connected to Tomari-te through the karate master Gikei Yamazato. Some believe the Shotokan version was developed by Itosu, and may be seen as a kind of Jion-sho. See more information here. ~ GE
