Wan Jin Yao
Wan Jin Yao is the ancient popular Okinawan Dit Da Jow used for training in Goju Ryu, Shito Ryu and Shotokan and is called Yi Yao Jia Zhi Wan Jin in Chinese, loosely translated means “medicine worth 10 thousand pieces of gold”.
The name has been shortened and is referred to as “Wan Jin Yao”. In Japanese it is translated to “Kin yori yakuyō-chi”.
What makes Wan Jin Yao so special is its ability to toughen and harden the Hands, Forearms, and Shins. When training on the Makiwara or Kotekitae training (Forearm Training) this liniment is very important.
Morio Higgaonna Sensei 10th Dan used Win Jin Yao prior to all Makiwara and Ishi Toreningu(Stone Training)training, he attributed his use of Win Jin Yao as the reason he suffered no ill effects from years of brutal hand conditioning.

Toreningu Training
Makiwara Training
Okinawan gojuryu master Seikichi Toguchi liked to point out, that Makiwara training is essential to develop a powerful, focused punch that can be delivered without creating unnecessary tension in the arm.
Makiwara training is more for strengthening the wrists than creating calluses and big knuckles but that is what happens with continued intense training. To prevent future hand problems it essential to use Win Jin Yao before and after contact training.
This is also very useful prior to and after Tan (Barbell) training, this is a very tough workout on the arms and forearms so using Wan Jin Yao really helps with the conditioning process. This should only be practiced after years of training as it is very difficult.
