Japanese kamons, or mons, are symbols of the histories and lineages of Japanese families, and hold deep meaning. Kamons date back to around the 9th century, when they were used by noble families to stylishly decorate their possessions.
When Japan later became a military society, crests were displayed on flags, swords, armour and clothing to distinguish allies from enemies. Eventually, during the peaceful Edo period, kamons came into everyday use by the general population. Since then, kamons have been a fundamental part of Japanese culture.
