Japanese railway company Seibu Railway (Tokorozawa, Saitama Prefecture) has fully deployed camper vans as mobile rest stops since spring 2026 to protect workers from heatstroke during extreme heat.
A pilot project in summer 2025, initiated after employee suggestions, received positive feedback: workers noted comfort and improved work efficiency. The base vehicle is a Vantec 'Cordbanks 4.11' (also referred to as Vantech Cordobanks) on a Toyota Camroad chassis, accommodating 6 people. It is equipped with air conditioning, a refrigerator, a microwave oven, and a toilet.
Additionally, the company introduced 'heatstroke monitoring watches' for 650 employees and a digital symptom reporting system.
