Kobayashi Pharmaceutical Azuki no Chikara Reusable Steam Eye Pillow – Natural Azuki Steam

The Kobayashi Pharmaceutical Azuki no Chikara Eye Pillow is a reusable microwaveable warming pillow designed to gently warm the eye area using the natural moisture contained in azuki beans.

Instead of relying on disposable heating sheets or electric heating elements, the pillow uses a filling of azuki beans and mung beans that naturally contain moisture. When heated in a microwave, this moisture is released as warm steam, creating a soft and comforting heat around the eyes. 

The product is designed for simple everyday relaxation after activities that place prolonged focus on the eyes, such as computer work, reading, studying or other close-up tasks. It can also be used after bathing as part of a relaxing evening routine. 

One of the distinguishing features of Azuki no Chikara is its natural bean filling.

Azuki beans naturally retain a relatively high amount of moisture. When the pillow is heated in a microwave, moisture contained in the beans turns into warm steam. After use, the beans gradually absorb moisture again from the surrounding air, allowing the pillow to be reheated and reused after sufficient cooling and resting time. 

After heating, the surface temperature reaches approximately 40°C, and the warmth lasts for around 10 minutes, providing a short and convenient relaxation period without requiring continuous reheating. 

The product can be reused approximately 250 times. When used once per day, this corresponds to roughly eight months of use. 

A built-in overheating warning indicator adds an extra level of safety. If the pillow has become too hot after microwave heating, the surface displays the Japanese warning text indicating that it should not yet be placed over the eyes. The pillow should only be used after the warning has disappeared and the temperature is comfortable. 

Using the pillow is simple.

First, remove the product from the transparent storage bag and spread the beans evenly inside the pillow. Place it flat in the center of the microwave with the printed side facing downward.

Heat it for:

• 500W: 40 seconds
• 600W: 30 seconds

After heating, place the pillow over closed eyes with the printed side facing upward and use it for approximately 10 minutes. 

The pillow must not be heated at power levels above 600W, and automatic microwave heating modes should not be used. It is also intended only for microwave heating and should not be heated using other appliance functions. 

At least four hours should be left between heating sessions so that the beans can naturally recover moisture before the next use. 

The exterior is made from a combination of polyester and cotton, while the internal filling consists of azuki beans and mung beans (green azuki).
