Nigiri Game XL

Grip strength is one of the most important and underutilized elements of martial arts training. Not only is grip strength important for making a tight fist but it is key for grabbing techniques. 

In traditional Okinawan Karate all exercises that used non-body weight tools are called Hojo Undo or supplementary exercises. They use many traditional and unique training tools. These are called Nigiri Game, or gripping jars. The lip at the top is grasped between the fingertips and the entire last part of the thumb. Then weight is added to the jar to increase the difficulty. The original jars were made from ceramic and were notorious for breaking. These jars are made of very sturdy PVC and are virtually unbreakable. The original jars were weighted with water or sand which was difficult to make even and would spill all over the floor when inevitably they broke. These jars are loaded with 2.5lb (1kg) or 5lb (2kg) standard size weight plates. You can load any weight from 10lbs (4kg) to 105lbs (47.7kg). 

This listing is for the XL model of nigiri game, gripping jars. They are roughly twice the size of the regular nigiri game. I made the first set as a kind of proof of concept, and instantly fell in love with them. They are simply put the best nigiri game that I can make. I use a set of these as my personal nigiri game. Each jar weighs about 10lbs (4kg). They operate the same way as the regular jars they are just bigger and more awesome.   

Looking to build your dojo? These jars use the same weights as the standard chi ishi

In the box: 2 nigh-indestructible XL PVC gripping jars

                 2 weight collars

Weight plate not included.

Please contact me if you have any questions. Nigiri Game are just a part of a whole line Hojo Undo equipment I make including:  olympic and standard weight sized chi ishi handles, makiwara(striking posts), and kongokens (weighted oval invented by Chojen Myagi). There are virtually no suppliers of these items so I'm happy to do my part. Find pictures for all our items on ourFacebook page.
