Kobayashi Pharmaceutical Azuki no Chikara Reusable Steam Heat Belt – Waist, Back, Neck & Shoulders

The Kobayashi Pharmaceutical Azuki no Chikara Anywhere Belt is a reusable microwaveable warming belt designed to provide gentle warmth to multiple areas of the body, including the waist, lower back, back, neck, shoulders and abdomen.

Unlike disposable heat packs or electrically powered heating pads, Azuki no Chikara uses the natural moisture contained inside real azuki beans. When heated in a microwave, the moisture stored within the beans is released as warm steam, creating a soft and gradually spreading warmth.

The long belt-style design makes this version especially versatile. It can be placed over the body, wrapped around suitable areas, or gently pressed against the area you want to warm.

With an overall belt length of approximately 133 cm, it is designed to reach areas that can be difficult to cover comfortably with a conventional rectangular warming pillow.

The attached straps help hold the warming section in place around the waist or back, allowing you to move more easily while using it.

It can also be placed across the shoulders or back while sitting or relaxing.

For the neck area, the product should be placed against the area rather than tied around the neck.

The warming section contains 100% azuki beans.

Azuki beans naturally contain moisture. When they are heated in a microwave, part of this moisture is released as steam. After use, the beans gradually absorb moisture again from the surrounding air, allowing the product to be reheated after an appropriate resting period.

This natural moisture cycle makes the belt reusable approximately 250 times.

When used once per day, 250 uses corresponds to approximately eight months of use.

A minimum interval of four hours should be left between heating sessions so that the beans have enough time to recover moisture before being reheated.

The product provides approximately 25 minutes of warmth, making it suitable for a relaxing break after work, study, household activities or other everyday routines.

It is especially convenient for use after bathing, while relaxing on the sofa, during desk work or before bedtime.

The product can be used in several different ways depending on the area you want to warm.

For the waist, the straps can help keep the warming section positioned around the body.

For the lower back and back, it can be wrapped, positioned or gently pressed against the area while sitting.

For the shoulders, it can be rested across the upper body.

For the abdomen, the warming section can be placed comfortably over clothing.

The outer fabric is made from a combination of polyester and cotton, while the filling consists of natural azuki beans.

One side features a soft raised surface designed to face toward the body during use.

The natural weight of the azuki beans helps the warming section settle comfortably against the body, allowing the heat to spread across the covered area.

Using the product is simple.

Remove the belt from its transparent storage bag and make sure the beans are distributed evenly inside the warming section.

Fold the product in half with the printed side facing inward, place the straps over the azuki-filled section, and position it in the center of a clean microwave.

Heat according to the microwave power:

• 500W: 1 minute 40 seconds
• 600W: 1 minute 20 seconds

Do not heat the product at more than 600W.

After heating, position the soft raised side toward the body and use for approximately 25 minutes.

The product should be used over clothing rather than directly against bare skin.

Automatic microwave heating modes should not be used.

Do not use oven, grill or other heating functions, and do not exceed the specified heating time.

The product should not be reheated immediately after use. Always allow at least four hours before the next heating cycle.

Over repeated use, the azuki beans gradually become less able to retain moisture. Once the product reaches approximately 250 uses, it should be replaced rather than continuing to reheat it.

The product is not washable. It should be stored in a cool, well-ventilated place when not in use.
