The Japanese bow and arrow are called Yumi and Ya, Japanese war archery is called Kyujutsu (Kyudo being a modern version, more of a meditation than a sport).
Of course Ninjutsu employs the yumi and Ninpo kyujutsu, Ninpo archery, is covered ...in different ryu.
We have already demo'd the modern fibreglass bow at class, so future Grass Days will be an opportunity to cover and investigate the use of Ninpo kyujutsu in contemporary environmental context.
It's not all shuriken and blowdarts after all ;)
