Lightweight Nagahama Hon-Ichikoshi Chirimen
Genuine silk, still woven today.
Nagahama first-class silk crepe, white fabric. From 10cm, as much as you need.
I don't want this silk to die out.
Nagahama, Shiga, was once known as Japan's top chirimen silk crepe production area. With the declining demand for traditional Japanese clothing, the production area has shrunk to an unprecedented degree.
Nevertheless, artisans continue to weave the finest white silk fabrics in Japan.
Even under such challenging circumstances, the quality of the products is truly exceptional. We want as many people as possible to experience this authentic silk.
With that in mind, we developed a completely new hitokoshi chirimen.
Hama Chirimen Today
From 1.85 million tan to 8,000 tan today.
The art of making Nagahama chirimen boasts a history of approximately 250 years.
It is characterized by high-quality raw silk, tightly twisted threads, and a plump texture.
Nagahama was once a top-tier white fabric production area, where a single weaving mill would handle everything from sourcing and twisting the yarn to weaving and finishing the fabric.
As demand for traditional Japanese clothing declined, production continued to decrease. Now, even with all types combined, annual production is only about 8,000 bolts.
If we look specifically at Ichikoshi chirimen, production numbers plummeted from approximately 600,000 bolts in 1972 to a projected 127 bolts in 2025.
Even so, seven artisans continue to uphold and preserve this top-quality white fabric.
Only white fabrics refined through the cooperative are called "Hama Chirimen."
New Ichikoshi Chirimen
Let's get our hands on some genuine hitokoshi.
In the world of Tsumami Zaiku, "Hitokoshi Chirimen" is a well-known and trusted fabric name.
However, much of the Hitokoshi Chirimen currently available is made from chemical fibers such as rayon or polyester.
What we offer is "Hon Hitokoshi" made from pure silk. It has an elegant luster and feel that only real silk can provide.
And—because it's silk, you can dye it yourself.
A brand new Hitokoshi, the first in 116 years.
Ichikoshi chirimen originated in Nagahama in 1910.
We couldn't let authentic ichikoshi chirimen disappear.
With that in mind, 116 years after its birth, we created a new ichikoshi chirimen, woven as thinly as possible, specifically for tsumami zaiku.
A typical bolt of ichikoshi weighs approximately 750 grams.
By using finer threads and innovative weaving techniques, we reduced the weight to about 520 grams.
Even at this thinness, the fabric remains stable, a testament to Nagahama's reliable weaving technology.
It's easy to fold and light even when layered.
Each small petal settles beautifully. It's a new form of silk for artisans.
In 2025, only 127 bolts of ichikoshi chirimen were woven in Nagahama.
It is a rare silk, with very little produced even in its place of origin.
New forms for silk fabrics.
Ohari Bako began as a silk thread wholesaler in Nishijin, Kyoto.
Since our founding, we have always worked with silk.
And it is precisely because of our deep connection with silk that we propose this hitokoshi chirimen as a new form of silk fabric.
Not just for kimono, but for everyone who loves handicrafts.
Authentic silk, in just the right amount.
Lightweight Nagahama Hon-Ichikoshi Chirimen (Pure Silk, White Fabric)
100% pure silk (Hon-hitokoshi crepe)
Shiga / Nagahama (Hama Chirimen)
Approx. 38 cm
Approx. 13m (one tan)
One roll: approx. 520g (basis weight approx. 105g/㎡, 24 momme)
27th 9,900 bottles
27th count, 6 threads / 3,300 twists (authentic crepe)
White (undyed; can be dyed to your preferred color)
Different in thinness and grain.
Even with the same "chirimen" (crepe), the thickness and texture of the crepe grain (shibo) vary significantly depending on how the weft threads are woven (number of warps crossed).
Oharibako's Ichikoshi is a "light Ichikoshi" woven as thin as possible specifically for tsumami zaiku (folded fabric flowers).
Compared to standard Ichikoshi chirimen (approx. 750-760g), the fabric weight is about 30% lighter (approx. 520g), making it thinner and easier to fold.
The crepe grain is the finest, and it remains light even when folded multiple times.
Each small petal will be beautifully defined.
