When I was young I studied several Martial Arts.
Ninjutsu was one of them.
( Monique had a workshop from Masaaki “okay lets play” Hatsumi )
Ninjutsu (忍術), sometimes used interchangeably with the modern term ninpō (忍法), is the martial art strategy and tactics practised by the ninja.
I alway liked the movie “Revenge of the Ninja”.
I like Sho Kosugi
