Since the middle Ages sword dance was performed by the samurai.
The samurai did this before battles, to pray and to commemorate the souls of the dead.
In today's Japan, there are just a few sword dancer.
The reason is that swordsmanship is seen as purely functional and is not considered to be shown on stage.
In contrast, dance is considered as a fine art.
Connecting these two and putting them on stage is very difficult.
Connecting the paradox of functionality and decorative beauty is the art of the Samuraidance Kenbu.
The IAI, the arts of the samurai. And the traditional dance born from Kabuki.
To illustrate this, the haiku of the old Samurai and Japanese instruments are braught together on stage to show the soul and history of the Samurai.
