In Japan, this plant symbolizes the samurai's courage, because of the swarthy form of its leaves that resemble the fighting swords, or katanas, which the warriors used for seven centuries.
To remember these past glories, the Tangu is celebrated on the Sekku (boys' day) every May 5th; on that date the male children take a bath scented with this plant (shobu-yu) due to the belief that her powers will preserve them from all evil, and inspire them to succeed.
The Japanese Mini-calamus can be used on the edge of water mirrors, since it is marshy and also ciliary, and its roots may have permanent or periodic contact with water. Little fishes and frogs love the clump that forms herbaceous and make it their habitat.
