Han-eri Day: Kimono Collar Day (Han-eri no Hi)

What Is Han-eri Day?

Every year on January 15th, Japan observes "Han-eri no Hi," established by the Kyoto Han-eri and Furoshiki Wholesalers' Cooperative. The date was chosen because January 15th used to be "Coming of Age Day" (Seijin no Hi) in Japan, a day when young women traditionally wore long-sleeved furisode kimono. The cooperative wanted people to take a fresh look at the han-eri — the decorative collar that adds so much color and elegance to a furisode outfit. It's a day to rediscover the charm of this small but powerful accessory that shapes the entire impression of a kimono.

What Is a Han-eri?

A han-eri (literally "half-collar") is a removable decorative collar sewn onto the collar of a juban, the under-kimono worn beneath the outer kimono. The small sliver of han-eri visible at the neckline has an outsized effect on a person's overall appearance and the impression their kimono makes — it's a uniquely Japanese item that combines practicality with ornamental beauty.

The Role of the Han-eri

The han-eri originally served a very practical purpose: protecting the collar of the juban from getting dirty. The area around the neck is especially prone to sweat, oil, and makeup stains. By attaching a removable han-eri that could be taken off and washed separately, people could keep their expensive juban clean for much longer.

Types of Han-eri

Today, han-eri come in a wide variety of materials, patterns, and colors, making them an important part of putting together a kimono outfit. Choosing one to suit the occasion or season is part of the fun.

Classification by Material

• Shoken (pure silk) — elegant sheen, ideal for formal occasions
• Shiose silk — smooth to the touch, the most commonly used material
• Chirimen (crepe silk) — textured with fine wrinkles, gives a warm feel
• Ro and sha (sheer silk weaves) — translucent and cool, used for summer kimono
• Synthetic fabrics / polyester — easy to care for, convenient for everyday wear

Colors and Patterns

The most basic option is a plain white han-eri, which works for everything from formal ceremonies to casual outfits. For Coming of Age Day, furisode are often paired with elaborately embroidered han-eri. Colored or patterned han-eri serve as a stylish accent for those who enjoy kimono as everyday fashion.

How to Choose a Han-eri

• For formal occasions, choose a plain white or pale-colored han-eri
• For furisode, choose a vibrant one with embroidery or beadwork
• Choose a color that brightens your complexion for a fresh impression
• Aim for harmony with the colors of your kimono and obi (sash)
• Add a playful touch by choosing a pattern that reflects the season

Attaching and Caring for a Han-eri

Traditionally, a han-eri is hand-sewn onto the collar of the juban. Nowadays, double-sided tape or special clips make it possible to attach and swap out a han-eri easily, even for beginners. Because it's removable and washable, regularly switching it out helps keep your kimono looking fresh and clean.

The World of Kimono, Opened Up by What's Around Your Neck

The han-eri is only a small part of a kimono outfit, but its influence on the overall look is far greater than its size suggests. Since it sits right next to your face, the color and pattern you choose can completely change the impression you give. Why not use Han-eri Day as a chance to pay closer attention to this small but mighty accessory? You might find that it makes kimono feel more accessible — and more fun — than ever before.
