Japanese company Trusco has launched a walk-in refrigerator to help employees cool down during a severe heatwave [1].
The initiative addresses the increasing frequency and intensity of extreme heat in Japan. By providing a controlled cooling environment, the company aims to protect workers from heat-related health risks and exhaustion [3, 5].
The device, known as the Dohiemon BOX, is a large cooling chamber that allows workers to step inside and sit for a few minutes [1, 4]. This provides a rapid reprieve from the high outdoor temperatures common during the summer months [1].
Reports said the interior temperature of the human fridge is maintained at approximately 15 °C [2]. This significant drop in temperature allows the body to recover quickly before the employee returns to their duties [2].
Companies in Japan are investing in these units as part of a broader effort to adapt workplaces to a changing climate [2]. The use of such technology reflects a shift toward specialized infrastructure to manage extreme weather events [5].
While traditional air conditioning is common in offices, the Dohiemon BOX is designed for environments where full climate control is not feasible. It serves as a targeted intervention for staff facing the most intense heat [1, 2].
The rollout comes during a period of intense heatwaves that peaked in July 2026 [1, 4]. The adoption of these cooling boxes suggests a growing reliance on industrial-scale cooling solutions to maintain labor productivity, and safety [2, 5].

The introduction of walk-in cooling chambers signals a shift in occupational health standards as extreme heat becomes a systemic risk. Rather than relying solely on hydration or breaks, companies are implementing industrial hardware to physically lower core body temperatures, indicating that standard cooling methods may no longer be sufficient for worker safety during peak summer months.
