A unique feature of Wado-Ryu is that the position of Grand Master is still handed down from the current Master to the next generation family member who is most deserving of the title. This hereditary system was one prevalent in ancient Japan but is not seen today. In preparation for this succession, Master Jiro Otsuka began his training in Wado-Ryu at the age of fifteen (15).

There are presently 1,000 branch dojos throughout the world, with a membership of 40,000, which are under his supervision.
