Background
Japan’s summer has seen temperatures rise to record highs, with over 53,000 heat‑stroke cases treated and 79 deaths reported in the past two months. These extreme conditions have spurred health officials to seek new ways to protect citizens.
The ‘Human Fridge’ Concept
The “Do Hiemon” (Cooling Box) is a standby unit designed to offer immediate, air‑conditioned relief in public spaces. Each unit costs 1.5 million yen (about $9,400) and can be sold to businesses or installed in transport hubs, stadiums, and office buildings.
Design Inspiration
According to CEO Testsuya Nakayama, the unit’s design mimics the layout of freezer vending machines, allowing efficient airflow and reduced energy consumption. The aim is to provide sudden, localized cooling without relying on large, city‑wide air‑conditioning systems.
Field Test
BBC's Tokyo correspondent Kurumi Mori tested the unit in a bustling location. She found that the air inside the fridge cooled quickly and that the device could help mitigate heat stress among commuters.
Implications for Public Health
By offering a portable and affordable cooling option, the Do Hiemon could reduce heat‑related incidents in hot weather. The public and private sectors are expected to invest in these units as a preventative measure against the growing heatwave threat.
