As Japan continues to grapple with intense heatwaves, experts suggest that strategies employed during the Showa era (1926-1989) could still be effective today. These old-school solutions to combat heat stress, including natural ventilation and shading solutions, are being reassessed in the face of rising global temperatures. While modern-day technology struggles to maintain a sustainable and eco-friendly atmosphere, these historical methods provide a reminder that cooling solutions do not always require high-tech systems or electricity.

The heatwaves are a critical concern in Japan due to the country's dense population and significant urban heat-island effect. In Japan, the issue of heatwaves often stirs discussions about sustainable living, energy consumption, and elderly health concerns. The reintroduction of Showa-era strategies taps into nostalgia and the societal value placed on traditional ways of life and wisdom.

While the US and EU often respond to heatwaves by increasing air-conditioner usage—which in turn contributes to the cycle of global warming—the focus on rediscovering and implementing traditional, eco-friendly ambient cooling methods sets Japan apart. This reveals an interesting cultural divergence in addressing environmental challenges.
