Ninjutsu is a weapons intensive system. The use of weapons correctly/ historically is of top priority for the Koga Ryu Ninjutsu Society. The order in which the weapons will be studied depends upon the intructor, but all are encourage to keep to the order listed below. This is the official list of KRNS weapons. These weapons have been research and experimented with, in order to provide the most accurate training possible. Although there are other weapons associated with Ninjutsu (which may not be listed) these weapons are the core/base weapons of the KRNS and are those which are required for rank advancement, international seminars, etc. Each weapon is truly an art within itself and should be treated in such a manner.
