Ice Japan: Long-lasting coolness!!
Muroran Hyakkoi Mat - a cooling mat that can be used without freezing in the freezer, with a cooling material cover!!
The main unit is set to a temperature of 29°C to cool the body without overcooling, providing comfortable sleep. We have applied control technology similar to that used by JAXA to ensure that the cool, comfortable temperature lasts for a long time.
The cooling material inside the main unit gradually absorbs body heat and liquefies, so the coolness lasts longer. It solidifies again at room temperature (0-29°C) without freezing, allowing for repeated use.
The main unit is manufactured entirely at the manufacturer's own factory in Muroran.
A key feature is that it doesn't freeze in the freezer, so the cooling agent doesn't melt and cause condensation.
It's less likely to wet your head or clothes, so you can use it by placing your head directly on it if you prefer.
It's a large size that won't shift even when you turn over, and it has a soft texture.
The dedicated cover is machine washable at home, so you can keep it clean.
