Unlike standard Okinawan sanchin jars that are made of red clay and can easily shatter if dropped, ours are made from a mixture of polyresin and granite dust. We wouldn’t call them unbreakable, but they are very shatter resistant. We have dropped them from 4 feet high onto a concrete floor with no visible damage. Color variation in our jars is standard because each jar is individually hand rotocast from a separate batch of resin. Once the casting has begun we can’t stop it to check the color until the process is complete. We match the jars as close as possible and can email pictures of your set(s) prior to shipment if desired.
Our jars are available in a granite color, or painted black with the 3 kingdom symbol painted red for an additional fee.

The nigiri game or sanchin jars are gripping jars that vary in size and design. They are normally filled with sand or gravel to alter the weight as preferred. The jars are to be gripped with the tips of the fingers and then the inside of the second joint of the thumb. It may be gripped by all of the fingers if necessary and by the lips themselves, then performing stepping techniques similar to those in the Sanchin kata. The jars may also be lifted from knee level to shoulder level while keeping the arms straight, which stresses the shoulders and upper back, as well as the wrists and fingers.
Nigiri Game (Gripping Jars) were simply jars used for foodstuff; they were readily available items that could be used for strength training. They would be filled gradually with sand, stones or water. Since all the components were free and readily available, it made a great training tool. Unfortunately, the jars can no longer easily be found.
Nigiri-game are widely used in Goju-ryu, Uechi-ryu, Shohei-ryu and some Shorin-ryu dojos to develop gripping strength in the hands. This strength is very useful when performing grappling motions or in simply grabbing any portion of the human anatomy. This type of training also strengthens the muscles in and around the shoulders, especially the trapezius as well as working the lower body and helping to improve posture.
Our jars resemble sanchin jars seen in Okinawa. The mouth of the jar is 4 inches across; it fits a standard person’s hand. The jars are 14" tall and 8" wide at the widest point. They weigh approximately 6 lbs per jar. Additional weight is possible by adding pebbles, stones, sand etc. equally to each jar.
