What Is Mawata?
Mawata is silk opened from the cocoon — soft, light, and quietly luminous.
Mawata is silk made by opening the silkworm cocoon into soft, layered sheets.
It looks almost like cotton, yet it is not a plant fiber but something born from the cocoon.
Light, soft, and quietly lustrous, mawata has long been used in Japan for bedding, kimono, and fine cloth.
At yamamayu, mawata is valued not simply as a material, but as something that continues into thread, cloth, and everyday life.
What Mawata Is
Mawata is made by softening the cocoon, removing the pupa, and opening the cocoon into thin layers.
From there, it can be drawn little by little into thread, spun by hand, dyed, and woven into cloth.
Beyond the form of the cocoon lies a soft silk with air inside it.
That is mawata.

Mawata and Cotton
Mawata
Silk born from the cocoon.
Light, warm, and softly luminous.
It continues into bedding, kimono, fine cloth, and hand-spun yarn.
Cotton
A plant fiber born from the cotton boll.
Durable and absorbent, it is widely used for everyday clothing and towels.
Both are natural materials, but they carry warmth and light in different ways.

Threads from the Cocoon
Reeled Silk
A long filament drawn from a good cocoon.
Smooth and even silk.
Dupion Silk
A silk taken from a double cocoon made by more than one silkworm.
It carries a distinctive texture with slubs and character.
Spun Silk
A yarn spun again from fibers taken from imperfect or leftover cocoons.
Balanced and practical in use.
Mawata to Spun Yarn
A yarn made by spinning mawata by hand.
It carries fullness, softness, and a quieter surface.
One cocoon does not end in one single form.
It continues into several kinds of thread, each with its own character.
Mawata is among the softest and most hand-led of them.

Mawata in Everyday Life
From the Meiji period through the middle of the Showa era, mawata was a familiar part of life in Japan.
It was treasured as something light and warm — for bedding, garments, and gifts for newborn children.
Part of its beauty lies in the older culture of using even imperfect cocoons well.
Though mawata may now seem distant from everyday life, its softness and quiet glow still make clear why it was cherished for so long.

From Mawata to Cloth
Mawata begins with softened cocoons.
The pupa is removed, the cocoon is opened and dried into something like soft silk cotton, and from there thread is drawn by hand, dyed, and finally woven into cloth.

Ways of Living with Mawata
Mawata can be enjoyed not only in bedding and kimono, but also in wall hangings, small objects, wreaths, and workshops.
At yamamayu, mawata is offered not only as thread or cloth, but as a gentle presence that can enter everyday life.
In a Living Cycle
At yamamayu, nothing given by the cocoon is treated as waste.
The pupa returns to compost, spent dye plants return to compost, and leftover thread is reused in what we call “mottainai art.”
This care for the living cycle of materials continues directly into the making of cloth itself.
Nothing from the cocoon is treated as waste. What remains continues in other forms, and this care for the cycle of materials is part of how yamamayu makes cloth.
