The sleeping environment is important for getting good quality sleep
The "2014 Sleep Guidelines for Health Promotion" published by the Ministry of Health, Labor and Welfare's Health Bureau states that the sleeping environment is important, as the quality of sleep can be reduced by factors such as the lighting in the bedroom before going to sleep and the environmental sounds heard while sleeping.

To soothe itching in or around the eyes, apply ice to reduce inflammation and relieve the itching.
Introducing a sleep support
eye mask that prevents light and sound
from disturbing your sleep


Whether you use it hot or cold, the temperature will gradually approach your body temperature, helping you sleep comfortably.

This is a reusable eye mask gel. It is comfortable to wear and you can sleep comfortably until morning.

Auto-fit material detects body temperature and conforms to the skin. It fits naturally to the contours of the nose and blocks light. It blocks light leaking through the gaps in your nose, leading to stress-free, comfortable sleep.
The 3D structure around the eyes creates a depression, and the design does not feel constricting, providing a comfortable, wrapped-in feeling even when worn for long periods of time.

Its high light-blocking properties block out light that can interfere with falling asleep, creating a good sleeping environment. Also, since sunrise times vary depending on the season, the sunlight can wake you up early in the summer, disrupting your wake-up time and disrupting your sleep rhythm. For this reason, eye masks are effective in creating a comfortable sleeping environment all year round.

The area from the eyes to the belt is designed with a cushioned one-piece design so that you don't feel any pain or discomfort even when wearing them until morning.

The hook-and-loop fastener allows you to adjust the length to suit your needs without feeling too tight, and the pad stays in place even when you turn over in your sleep. Enjoy a comfortable sleep all night long.

The eye mask itself is designed to be wrinkle-resistant and can be washed. It is also made of a quick-drying material, so it is easy to care for and can be used hygienically at any time.

The surface has been treated to prevent static electricity build-up and prevent dust, dirt, and pollen from sticking to it.

Man in his 30s (Customer Support DU)

I was exercising during the day on a nice sunny day and got sunburned and my body got hot, but when I used it with the cooler it was much better. It had good light blocking properties, a good fit and was very comfortable to useです。
TM, male, 50s (planning and development)

Recently, it's been cold at night, so I feel like I was able to relax and sleep better by keeping it warm .
The room is very sunny, so I woke up about two hours earlier than my normal wake-up time, but the eye mask's high light-blocking properties meant I was able to sleep soundly until my wake-up time .

Eye Mask Gel


How to wear an eye mask
Hold the eye mask in both hands and adjust it so that it fits around your nose. Wear it so that it covers your ears, and fasten the hook-and-loop fastener at the back of your head, being careful not to wrap it too tight. The guide for fit is that your index finger should fit smoothly around the side (near your ears), and you can adjust it to your preferred fit.
How to use hot and cold gel
Heat the hot and cold gel in the microwave (500W) for 20 seconds.
Chill in the refrigerator for at least 3 hours.

Just this one thing to prepare for sleep.
The eye mask itself can be washed at home. Separate it from other clothes, fasten the hook-and-loop fastener, place it in a laundry net, and wash it on a gentle cycle. If you are concerned about the hot and cold gel stains, wipe them off with a tightly wrung wet towel. Please refrain from using a washing machine.
