JPHEAT / FAR INFRARED TECHNOLOGY
Warmth begins with
ORIZUMI planar heating.
The heat comes from a single heating element made with water-based carbon.
This is JPHEAT planar heating technology, with no heater wire.

THE HEART OF WARMTH
From one ORIZUMI sheet
to everyday warmth.
ORIZUMI, a planar heating element made with water-based carbon.
It makes heat as a surface, with no heater wire.
JPHEAT warmth begins with this one sheet.
INSIDE THE COMFORT
5 layers, built up for comfort.
From the cotton outer fabric to the heat-spreading sheets around the heating element.
Each material has a role.

LINE / SURFACE
Heats as a surface,

All current JPHEAT products share
a planar heating element with no heater wire.
A woven mesh of water-based carbon

MATERIAL / ORIZUMI
From a fine mesh
to a heating sheet.
Water-based carbon in a fine woven mesh.
When powered, the mesh itself heats.
Threads, not one wire, warm as a surface.
LIGHT / Far infrared
Unseen light,
as warmth.
Far infrared is a kind of unseen light.
A warmed surface gives off this light.
Absorbed by an object, it turns into heat.
JPHEAT / Into daily life
Different forms,
one heating technology.
For time on the floor, for time to unwind in bed.
One shared heating technology,
shaped for where it is used.

MEASURED / JPT100J
We measured a test
sample of the JPT100J.
A test sample of the JPT100J was measured at a third-party testing laboratory.
The emission peak is about 8.35 μm, within the far-infrared (IR-C) range of the CIE classification.
Far infrared, by wavelength.
Beyond visible light,
the far-infrared range.
Infrared is light with a longer wavelength than visible light.
There are several standards for classifying it.
Shown here using the classification of the International Commission on Illumination (CIE).
The JPT100J test sample peak, about 8.35 μm, is in the IR-C range.[1]
The boundaries of near, mid and far infrared differ by field and use.
BOKEN, a textile evaluation body in Japan, describes 3–1,000 μm as far infrared.
The value here, about 8.35 μm, also falls in that range.[3]
Measuring emission characteristics.
Emission, checked
by wavelength.
Along with the structure, measurement data for a test sample is shown here.
This is something JPHEAT values in how it makes products.
A test sample of the JPT100J was measured at a third-party testing laboratory.
Relative intensity by wavelength is shown as one curve.
The wavelength at which relative intensity was highest among the recorded points.
This value shows emission characteristics under the test conditions. It does not indicate any action on the human body or compare power consumption.
Both are results for the test sample. Values differ with product construction and measurement conditions, even where the same heating material is used.

Start at a lower temperature and find the one that suits you. For long continuous use, about 30–38 °C is a guide.
This illustrates operation, with the display and lamps laid over a product photo. The numbers are an example. For actual operation, see the instruction manual.
DESIGNED FOR YOUR BEDDING
Lay it under the sheet.
Spread it on your futon and secure it with the elastic bands.
Add your usual sheet, and it is ready.

Safety information
- If a small child, an elderly person, someone who has trouble feeling heat or someone who cannot adjust the temperature alone uses this product, always stay nearby and watch over them.
- Start at a lower temperature and find the one that suits you. For long continuous use, set the temperature to about 30–38 °C as a guide. Staying in contact with the same spot at a higher temperature can cause low-temperature burns.
- Lay the unit under a sheet and do not use it in direct contact with your skin.
- At bedtime, please use the off timer.
- Before use, always read “Safety precautions” in the instruction manual.
What does DC 24 V (low voltage) mean?
Power from a household outlet (AC 230 V) is converted to 24 V DC by the included dedicated AC adapter, then sent to the unit. Just 24 V DC runs through the unit and the planar heating element. It is not rechargeable, so please keep the adapter plugged in during use.
Please check before use
Lay the unit flat and cover it with a sheet. Do not use it as a blanket or wrap it around your body. Do not turn it on while it has folds, overlaps or wrinkles.
Warming the same spot for a long time can cause low-temperature burns, even at relatively low temperatures. Start at a lower temperature. If an infant, an elderly person or someone who has trouble feeling heat uses this product, always stay nearby and watch over them. Do not use it to warm pets or for any other unintended use.
Care and storage
The unit is not washable. Turn off the power, unplug it and wipe off dirt with a damp, well-wrung cloth. When storing, fold it after the unit has cooled.
Warranty and product questions
The warranty period is 1 year. For details, please check the terms on the warranty card. Product questions are welcome by email.
