About
SPACECOOL INC. is a Japanese climate tech company that develops and commercializes passive daytime radiative cooling (PDRC) materials — advanced optical films and sheets that lower surface temperatures below ambient air without consuming any electricity. Originally developed at Osaka Gas, the technology works by simultaneously reflecting sunlight and emitting heat as infrared radiation into outer space, enabling zero-energy cooling for buildings, warehouses, vehicles, outdoor equipment, and sun protection gear. Founded in 2021 by CEO Masahiro Suemitsu, SPACECOOL is headquartered in Tokyo and is commercially deploying its films across industries including construction, transportation, and agriculture.
