KM03J is specifically designed to help your head turn smoothly during sleep. Its broad, bean shape and carefully selected stuffing materials are the result of our over 90 years of experience in manufacturing sleeping goods designed to maximize the quality of your sleep.
KM03J is YOUR pillow. We recognize that each person has their own preference when it comes to pillow height. KM03J is designed to enable personal height adjustment and promises to become your own special pillow.
Each pillow is made in our factory in Japan. Our goal is to provide our customer as well as ourselves, who also use a pillow, with a confidence in KM03J's quality, safety and security.
Though it is not well known, we sweat around 200ml per sleep. Anatomically, our head prefers a lower temperature than any other area of body, and thus, it is more likely to produce sweat to release the heat. KM03J is fully washable for you to be able to continue experiencing a clean, comfortable, and refreshing sleep.

- Please use the pillow in these directions
- On your back, please use the center area
On your side, please use the side areas.
- How to check for the right height of your pillow
- To ensure that your pillow is set at the correct height for you,
check at two points: on your back and your side.
If possible, we recommend you have another person help you check the side.
- On your back
- □ Your jaw is facing up. You are feeling pressure on your neck → B is too high.
□ Your jaw is facing down. Wrinkles are formed around your neck → B is too low.
□ The back of your head is up → Either A is too high or B is too low.
□ The back of your head is down → Either A is too low or B is too high.
- On your side
- □ Your head is up → C is too high.
□ Your head is down → C is too low
- Instruction for adjustment
- Use funnels and measurement spoons to remove, little by little, materials inside. Please make sure to assess pillow
height occasionally by laying on it. To measure the amount necessary to shift one size down, please refer to the figure

We spend about one third of our lifetime sleeping. In order to get the wonderful sleep we all need, it is necessary to take a good care of your pillow. We recommend occasional hand wash and drying under the sun so that you can experience the comfortable sleep you desire.
