In modern day Shotokan training, self-defense aspects are of minor importance. For Shihan Nakayama, however, Goshinjiyu (護身術, engl. self-defense) seemed to be a vital element of Shotokan – also against weapons. For a closer look, see the following classical movie. Shihan Nakayama together with a very young Hirokazu Kanazawa, Keinosuke Enoeda, and Tetsuhiko Asai presents some Shotokan techniques in order to deal with an attacker on the streets.
