Sleep Science & Bedding Specialists
Chuo-ku, Kyoto



Providing you with a healthy sleep through the year, - that's our passion -

We develop our products based on sleep science. Sleep is needed for us to live. We do a lot of important things while we sleep, such as build up our immune system, grow and repair our bodies, and heal from stress and fatigue. We think bedding should not only be comfortable but should also be functional to support good sleep. We have researched sleep, from the mechanisms of the body, position in bed, the frequency of rolling over, to temperature and humidity, all factors informing our product development. In our Comfortable Sleep Laboratory, we scientifically evaluate various products and use the results for our continuing education and development. Our exceptional reputation lies not just in our fine stitching and quality materials, but also in our practical efforts to understand the condition of the body during sleep.


Our products are manufactured in Japan, by artisan-level professionals.

IWATA&rsquo's products are manufactured in our own factories and at the factories of reliable partners, all in Japan. We use quality fabrics that are woven to on our own standard. IWATA Down Laboratory checks the fabrics thoroughly. The fabrics are cut one by one by craftsmen and sewn with lock-stitch sewing machines. Needles, yarn, and other tools are also carefully selected. Skilled professionals manufacture our bedding one by one with care and attention.


IWATA has been making bedding for more than 180 years.

We are one of the oldest bedding makers in Japan, dating back to the late Edo period in 1830. Over almost two centuries, IWATA has developed and patented improvements in many fields, such as down purification, fiber activation, and manufacturing optimization. Our technical achievements allow us to manufacture high-quality bedding using superior natural materials that are difficult or impossible for other manufacturers to process. Since our foundation, we have never taken advantage of our successful history, and we are always seeking for new techniques and quality control. We, as a pioneer of "sleep", are going one step ahead of the age.


We only offer you products that meet strict standards in our laboratory.

The IWATA Down Laboratory has contributed to our manufacturing for years. The Laboratory studies positive analysis for materials and improves our products and techniques. We only use materials that pass numerous tests to ensure safety and performance. IWATA has been certified ISO9001 (the international quality management system) at our factories and at the IWATA Down Laboratory. Because of our strict quality controls, we can use natural materials and natural processing free from chemical agents and create reliable and safe bedding.


We go to great lengths to detect harmful components in our raw materials.

Eco-Tex is an international testing and certification system for screening harmful substances in textile products. IWATA has received Eco-Tex certification on each of our products. From fill materials to shell fabrics, threads to fasteners, every single material is tested to prove its purity and safety.



Camel Hair Mattress Pad

This mattress pad is manufactured from 100% Bactrian camel hair from Mongolia. The camel’s range features extremes of cold and warm weather, which results in the high moisture regulating the ability of its hair. We use a blend of long hairs and fine, soft undercoat. The long, thick hairs of the Bactrian camel have a natural strength which comfortably supports body weight and distributes pressure evenly, preventing depression of the hips and helping maintain natural body position. The camel hair mattress pad can be used with any type of mattress.


We select the ideal materials to achieve high-quality bedding.
There are four seasons and the seasons effect not only our sleep but also the natural materials we use to make bedding. IWATA carefully selects materials from around the world, to promote comfortable, healthy, good sleep. We first visit the land where the materials are produced and validate the rearing environment, manufacturing capacity, quality level, management systems and other factors. We bring back samples, analyze, and then select based on our own strict standards. Validation, procurement, assay of materials, and securement of a supply route-this continuous cycle lets us choose safe and reliable materials.
