In Goju Ryu I've started learning my first weapons kata, the weapon used in this kata is the jo staff. I made the rank of yellow belt just this past Tuesday which comes right after white belt and so now Im learning a weapons kata. I do find it a bit unusual to learn a weapons kata so early in a Karate style, in some dojos you don't start learning weapons until you at least make 1st Dan and some Karate dojos don't even teach weapons at all but each dojo is different. As a white belt I was introduced to some weapons including the jo although none of the katas I learned at white belt had weapons and none of the katas or techniques needed to advance from white to yellow included weapons. Although this is different, learning weapons so early on, I like it and I like the jo, its a good, practical, and effective weapon to use.
