itowa ni hitotsu uchiwa
Uchiwa -- round, bamboo fans -- have been keeping the people of Japan cool for centuries. The actual act of fanning is said to both summon and serve as a channel of communication with the gods, so
uchiwa themselves are often used as a symbol of worship and displayed during Shinto festivals. In addition, special
uchiwa were used by military generals to direct troops during battle, as it was thought that using
uchiwa called upon god's authority and brought victory to the soldiers in the field.
The earliest known usage of the
uchiwa mon was the emblem of the Kodama Party, the central and most powerful of the Seven Parties of Musashi, a band of samurai active in the Kanto Region from the start of the Heian period (AD 1180~). It is one of the oldest mon in existence.
