Hemp is used in Shintoism to purify a parson.
These ropes are still used in Shinto shrine to create the barrier from the worldliness.
Having jude rope and using them is not for the practical issues alone.
Purification is an important belief in Shintoism. And it serve as a symbol of the God too. it used to be what common house holds prayed for.
I am Japanese. I would like to share the passion of the rope.
