Inside Japan’s portable 'human fridge' designed to beat brutal heat

Japan's 'Do Hiemon Box' is a portable human-sized refrigerator developed by SDRS and distributed by Trusco Nakayama.

The device maintains a steady 15°C interior and blows 5°C air toward the head and neck to rapidly cool users within 5 minutes.

An automatic 20-minute shutoff timer prevents overcooling; a 10-minute session can relieve heat exhaustion symptoms.

The standard model costs 1.5 million yen (about ₹8,86,300) and targets businesses, construction sites, and outdoor venues.

Tokyo has experienced temperatures exceeding 40°C, driving demand for such extreme cooling solutions.
