Genpuku

What it is

Genpuku was a Japanese ceremony that changed a young person's standing from child to adult. The word joins gen, meaning head, with fuku, meaning wearing, which points to the cap at the centre of the rite. A child gained a new adult name, a new hairstyle and grown-up clothes, and with them the duties of an adult. Both boys and girls went through it, though the sources describe the male form far more often, because women were shut out of politically important court posts and warrior rank.

Origins and history

Coming of age rites in Japan are recorded from at least 714 CE, when a young prince of Empress Genmei's reign put on new robes and a new hairstyle. Genpuku itself dates to the classical Nara period, 710 to 794, and drew on an earlier Chinese custom of the Tang dynasty. It flourished in the Heian period court, where aristocratic boys of roughly seven to fifteen went through it as a step toward a court cap and rank. It continued into the Tokugawa period, and in the Muromachi years it spread beyond the warrior class to farmers and artisans.

How it was held

The ceremony almost always happened in the evening, on a day chosen as auspicious. A person of influence, called the capping parent, took charge of the arrangements and helped the young person into adult clothing, most importantly the court cap, the kanmuri. Another official loosened the childhood hairstyle, cut the ends, tied a fillet around the head and made the boy ready for the cap. Afterwards the new adult withdrew to change into adult robes, and a feast followed. The choice of day and age rested with the parents.

Dress and objects

Clothing carried the meaning. Boys received headgear: a ceremonial court cap, the kanmuri, or later, in samurai households, a helmet. Adult samurai were given their swords and armour at this point. Girls, whose rite was usually called mogi, were given a pleated skirt instead. Their long hair, loose until then, was tied up on top of the head, and they blackened their teeth, shaved their eyebrows and used makeup. Before the ceremony, childhood dress was not divided by gender, and boys often wore makeup.

Today and change

Genpuku itself ended as a living court and samurai rite, but its shape is remembered in Japan's Coming of Age Day, a public holiday on the second Monday of January, fixed by the Happy Monday System. Local and prefectural offices hold ceremonies, called seijin-shiki, for everyone who reached maturity in the year running to April 1, and families and friends gather afterwards. The legal age of adulthood was lowered to 18 by a law that took effect in 2022, though drinking and smoking still begin at 20. The holiday and the ceremony are not tied to legal status.

How Genpuku is kept

Families decided the time, weighing the child's readiness for court service, the support of influential backers and the cost. The capping parent, usually a person of standing, arranged the day and dressed the young person. The rite was held in the evening on an auspicious day, at a dignitary's home or at the Shishinden. The childhood coiffure was undone, the hair trimmed and bound, and the cap or helmet put on. The new adult then changed into adult robes in private. Feasting followed, and with it a new name, marriage eligibility and adult duties.

When and where

Genpuku had no fixed date. Parents picked a day they judged auspicious, and the ceremony was usually held in the evening. The age varied widely with period, sex, politics and rank: aristocratic children were often between 10 and 20, samurai boys later came of age at 15 to 17, and by the early to mid-1800s at 13 to 15.

Genpuku belonged to Japan. It began among the court aristocracy and was often held at the Kyoto Imperial Palace, in the Shishinden hall, or at the home of a senior figure who sponsored the young person. It later became a warrior rite across samurai Japan, and in the Muromachi period it reached farming and artisan families as well.

What Genpuku means

Genpuku was more than a change of clothes. It moved a child into adult society, with a new name, new duties and the right to marry. In the Heian court, children were thought to be close to the kami, the gods, and were not yet seen as fully gendered; genpuku ended that in-between state. For samurai families the rite tied a young man to a senior warrior and confirmed the family's standing. Later it also marked entry into a trade.
