Cool Japan: Human Fridge Chills Workers in Extreme Heat

Trusco Nakayama has sold more than 300 units since April as companies seek low-power relief from heatstroke risks.

  • To combat heatstroke, businesses are deploying 'Do Hiemon Box' units; Tokyo-based distributor Trusco Nakayama has sold more than 300 units since April, priced at 1.5 million yen each.
  • Japanese businesses have faced tougher legal requirements since last year to protect employees; this year, the weather office began using 'kokushobi,' or 'cruelly hot day,' for 40C temperatures, urging the public to treat extreme heat as a natural disaster.
  • Warehouse worker Isao Tabuchi, 51, noted in Higashiosaka, 'I was really able to recover thanks to that'; the booth automatically shuts off after 20 minutes to prevent overuse.
  • A Teikoku Databank survey found 50 percent of companies reported heat-related operational disruptions, prompting increased investment in cooling measures; Yutaka Kono from Konoe noted such investments are essential for maintaining workforces.
  • Distributors plan to expand cooling units to golf courses and baseball stadiums, while scientists say human-induced climate change is increasing extreme heat frequency and intensity worldwide, making Japan's adaptation strategy increasingly critical.
