What is Naga-juban（長襦袢）?

If you’ve ever seen a kimono worn traditionally, you might be surprised to learn that what touches the skin is not the kimono itself, but a garment worn underneath it: the naga-juban.

A naga-juban (長襦袢) is a full-length under-kimono, traditionally worn directly beneath a kimono. Its original purpose was practical — to protect the outer kimono from sweat and wear — but over time, it evolved into a beautifully crafted garment in its own right.

 

A Hidden Layer of Beauty

Historically, naga-juban were designed to be seen only in subtle glimpses — at the collar, sleeves, or hem. Because of this, they became a quiet space for personal expression. Patterns, colours, and motifs were often refined, playful, or deeply personal, meant more for the wearer than for display.

Many vintage naga-juban feature flowing silhouettes, long sleeves, and carefully considered designs that rival the beauty of outer kimonos.

 

Materials: Not Only Silk

While many vintage naga-juban are made from silk, they were also produced in other materials depending on period, purpose, and season. You may find naga-juban made from:

• polyester or synthetic blends (especially later Showa-era pieces)
• cotton or linen for warmer months
• mixed fibers designed for durability and easy care

Today, these materials make naga-juban especially versatile — lighter, more breathable, or easier to maintain, while still offering elegance and movement.

Fit: No alternations needed

Naga-juban are made shorter than kimono, roughly in the 120–140cm range and usually don’t need tailoring - just style them as-is and shape the look with an obijime (silk rope-like decorative belt) or any other belt.

Men’s and Women’s Naga-juban: What’s the Difference?

Traditionally, naga-juban were made for both men and women, with subtle but important differences:

Women’s naga-juban

• Longer sleeves with more movement
• Softer colour palettes and more decorative patterns
• Designed to complement layered kimono styling

Men’s naga-juban

• Straighter lines and shorter sleeves
• Often darker, more graphic, or abstract patterns
• Designs, often breathtaking, are usually hidden entirely beneath the kimono

Today, many vintage men’s naga-juban are worn unisex, appreciated for their bold linings, graphic motifs, and relaxed silhouettes.

How Naga-juban Are Worn Today

Beyond traditional kimono dressing, naga-juban have found a new life in modern wardrobes. They are often worn as:

• elegant robes at home
• layered pieces over simple outfits
• resort or beachwear
• statement garments styled with a belt or sash

Their long lines and fluid sleeves create a sense of presence — effortless, calm, and quietly confident.

 

Why Vintage Naga-juban Are Special

Vintage naga-juban are rarely made today with the same attention to detail. Many were hand-dyed or carefully woven, reflecting the aesthetics of their time. Because they were worn underneath other garments, many remain in excellent condition.

Each piece carries history, craftsmanship, and intention — offering a way to wear something deeply traditional while feeling entirely contemporary.

 

Tradition, Reimagined

At CityZen, we see naga-juban as garments that bridge past and present. They invite slower dressing, personal ritual, and a kind of everyday elegance that doesn’t need to be loud.

Once hidden, now celebrated — the naga-juban is tradition made wearable for modern life.
