As Japan experiences record-breaking summer temperatures, a unique solution has emerged to combat heat exhaustion and heatstroke. The Do Hiemon Box, an oversized stainless-steel refrigerator large enough to fit a person, offers immediate relief from oppressive heat.
This innovative cooling booth, developed by Trusco Nakayama Corp., maintains a temperature of 15C and delivers jets of 5C air.

The company has noted a significant increase in demand for its workplace cooling products, with demand roughly doubling each year due to stricter government regulations and rising temperatures.
Trusco Nakayama Corp. sees potential for the Do Hiemon Box in crowded venues like shopping malls and summer festivals. Inquiries have been received from international markets, indicating a global interest in solutions for extreme heat.
