I hear there is how some farmers do in Hawaii also. There is always someone experimenting. I read and hear a lot about pruning all water sprouts from apples and pears... I visited a fig grower last weekend (some 35 trees) and other fruits, and he 'bend's the tall suckers down and tie them to other lower branches or lines to the ground - you would not believe the size of fruits on those ' water suckers'. Make sense, since they are very strong- if all the tree energy was put into those suckers, the tree should put out fruits on them also. I should have taken pictures - totally against the standard pruning methods I ever seen.
Sparked the idea -why not incorporate this method to my tree long/tall limbs? I was about to cut them out, but for the same of this experiment, I secured it to a long bamboo and I am lowering it to a reacheable size. (if the japanese method is natural, it should shoot laterals up with fruits. Now I wonder if I should clip the tip or just let it be. It is the stronger branch in the tree, so lets see how it produces next year.
