Tengu Verse 

We are Bujinkan Tengu

Of Hatsumi’s Dojo!

Mystical Guardians of the Divine Warrior Traditions

We Honour this

To enlighten our Souls by observing the Universal Laws

And continue our Mission

In our Quest for Peace and Development

May the Martial winds from ages past will guide us in our path

 Nin Sei Shin Jihi no Kokoro

Shiking Haratmitsu Daikomyo

Ninpo Ikkan!!

 

Alfredo Castan, Shihan
