Japanese outlets report on the Do Hiemon Box, an oversized stainless-steel refrigerator designed so a person can step inside for direct cooling. The units resemble large glass-door refrigerators and are intended to deliver cool air quickly to the head, neck, and shoulders when the door is closed. The company Trusco Nakayama has reportedly sold about 200 of the boxes. Each unit is priced around 1.5 million yen (about US$9,500), according to one report. Buyers described across coverage include steel mills, construction sites, golf courses, universities, and leisure facilities, suggesting the boxes are aimed at work and outdoor settings during extreme summer heat. The products are marketed as a practical way to obtain immediate personal cooling compared with traditional room or vehicle air conditioning, though the reporting focuses primarily on the device’s design and distribution rather than on independent performance tests or broader adoption. Both sources describe the same core concept: a human-sized refrigerator box that provides rapid, targeted relief during hot weather.
