· date approximate Background
The Do Hiemon Box went on sale.
Earlier in 2026, the Do Hiemon Box was released for sale as a device to provide quick relief from potential heatstroke or heat exhaustion. Unlike a standard lounge, the oversized stainless-steel refrigerator is designed to fit a person and operates by maintaining a temperature of 15 degrees while blowing jets of 5-degree air once someone sits inside.
Since its launch, Trusco Nakayama has sold approximately 200 of these booths. The units, which cost 1.5 million yen (US$9,500), have been distributed to various locations including steel mills, construction sites, golf courses, universities, and leisure facilities.
