Weaponry was used not only for the practical purpose of fighting, but also as a symbolic offering to the gods to pray for their assistance in securing victory or to give thanks for a successful battle. All manner of weapons, including shields, swords, spears, and even guns, were presented to shrines and were sometimes used in their annual festivals.

In the 17th century the Tokugawa regime pacified Japan after centuries of intermittent warfare and the ruling elite became warriors in name only. As a result, displays of military power in the form of ceremonial weaponry took on increasing symbolic importance as a means of asserting the government’s authority and legitimacy.

The strong, valiant warrior continued to be held as an ideal for young boys. In a custom that continues today, miniature weapons and suits of armour (or sometimes even full-size ones) were presented to new-born sons to wish for their health and strength. These were displayed for the Tango-no-Sekku, celebrated on the fifth day of the fifth month (observed today as Boys’ Day, 5th May), one of five auspicious days (sekku) in the annual cycle.
