Product Description

Made from rare cocoons spun by Yamamayuga,
Use silk with a special fiber structure.
Cocoons that have protected larvae from sun, rain, and wind,
Now gently protecting the baby's skin.

The first touch should be genuine.
Because it is the first clothing worn after birth, baby undershirts are very important.The first items a newborn baby uses are truly their first touch with fabric. This is a very important moment for the baby. We want to be extremely careful about what touches the skin of a baby born with nothing on. With this in mind, "Silk Newborn Clothes" use Eri silk fabric, a blend of rare silk threads with a special fiber structure and high-quality extra-long cotton in an optimal ratio. It offers a comfortable feel, is lighter, and provides excellent UV protection as baby undershirts.

Like being inside a cocoon,
Gently Protecting Babies

To embody care for babies in undershirts, we focused on rare cocoons as the material. Instead of typical silkworm cocoons, silk made from Yamamayuga cocoons with a special fiber structure is used, resulting in undershirts that are not only comfortable but also lighter and superior in UV protection. Cocoons that have protected larvae from the outside environment now gently protect the baby's skin.

Professor at Tokyo University of Agriculture
Representative of the New Silk Road Project | Takayuki Nagashima

Professor Takayuki Nagashima of Tokyo University of Agriculture, who discovered the special silk made from Yamamayuga cocoons, conducts daily research on the wonderful functions of insects in the Insect Function Development Laboratory. He especially focuses on the characteristics and diversity of silk, stating, "Silk is not just the one type made by the silkworm we commonly know; over 100,000 insect species produce silk. Among this vast variety, I focused on the silk thread spun by Yamamayuga." This silk thread spun by Yamamayuga is the raw yarn for these "Silk Newborn Clothes."

Because they are the first clothes worn after birth,
Baby Undershirts Are Very Important

"Silk Newborn Clothes" have the unique function of cocoons that protect larvae from sun, rain, and wind.

Silk and Cotton
The Best of Both

By combining rare and excellent Yamamayuga silk with Pima cotton, which has a low global production volume and a soft texture, in an optimal ratio, even better functions and benefits have been created.

Meticulous Sewing

Using soft fabric, the stitching is done carefully with fine stitches. Skilled Japanese baby product sewing artisans gently finish each piece one by one.

The tag is placed on the outside so it does not touch the baby's skin directly.

Soft tape is used for sewing around the neck and thighs to avoid any stress on the baby's delicate skin.

The snaps are designed to fasten in the same color to prevent mistakes. Consideration is given to the person dressing the baby.

The natural color of the material itself is beautifully accented with elegant Blue embroidery.

Use According to the Scene

Change clothes according to seasonal and morning/evening temperature changes. As your baby grows day by day, they will return your care with a cute smile. It’s the happiest moment for moms and dads. We hope these pleasant times continue.

Case 1
Spring or Autumn Indoors and Walks

＋

Layering a Pre-All over the usual short undershirt prevents the belly from showing even when the baby moves around. This versatile, classic style is perfect for staying indoors or going for a walk nearby.

Case 2
Sleeping

＋

The combination undershirt made of smooth fabric with excellent texture is perfect for sleeping. Combined with a short undershirt, it’s great for temperature regulation.

Case 3
When It’s Hot

or

or

Babies sweat a lot. When the temperature rises, let them wear just one undershirt. For newborns who mostly sleep, a short undershirt is best. If the baby starts moving and you worry about the belly showing, a combination undershirt or romper is ideal.

Case 4
When It’s Chilly

＋

＋

On chilly days, layer a short undershirt with a combination undershirt that covers the belly. Over that, it’s recommended to dress the baby in a Pre-All that can also be used as outerwear. You can add a vest or more layers depending on the baby’s condition.

Easy Care

Even with a silk and cotton blend fabric, it’s okay to wash in the machine if placed in a laundry net. Since these are everyday clothes, washing should be easy. Yamamayu silk, which is strong against washing, is a mom’s ally.

Silk Newborn Clothes as a Birth Gift

When you receive happy news, the first recommended gift is underwear. Babies are born wearing nothing, so we want to be very careful about what touches their skin. Silk and cotton hybrid fabric Silk Newborn Clothes is made in Japan and perfect for gifts.

We received comments from expert doctors

Dermatologist｜Kazumichi Maruyama
What we want from baby clothes is gentleness on the skin and good moisture absorption. Newborn skin is very delicate, so this silk with excellent moisture absorption is very good for the skin. Please dress your baby in this carefully selected natural material.

Pediatrician｜Akiko Ogawa
Babies with high metabolism are always sweaty, so breathability is important. This Silk Newborn Clothes uses special silk, making it very suitable for babies. It’s also great for moms that it dries quickly after washing. Just wearing the Newborn Clothes provides UV protection, which is reassuring during walks.

Midwife｜Yoko Nanbu
Babies sweat surprisingly much. Their metabolism is active, so they need frequent outfit changes. They may be washed several times a day! For delicate skin, we want you to choose high-quality silk products and premium cotton materials that absorb sweat without stickiness and do not irritate.

Supporting Cambodia

〈 Silk Newborn Clothes Eco Cycle 〉

Yamamayu silk is currently a very rare raw yarn and therefore very expensive. If we can make this wonderful yarn more accessible, we can create comfortable and safe clothing not only for babies but for everyone. By supporting Cambodian farmers where many trees favored by Yamamayu moths still exist, we can make this silk more accessible. We believe this is an important mission that benefits not only us but also supports Cambodia.

As a token of gratitude from everyone who purchased Silk Newborn Clothes, we would like to donate a portion of the sales to support Cambodia.
