Every year, starting in June, Japan transforms. The Japanese summer isn’t just hot: it is heavy, enveloping, saturated with a tropical humidity called mushi-atsui. Yet, long before the invention of electricity and air conditioners, the Japanese knew not only how to survive, but how to sublimate this stifling season through a remarkably resilient art of living.
While Europe faces increasingly intense heatwaves, Edo-period techniques offer a formidable source of inspiration for a more ecological, slow, and poetic summer.
“Designing the house for summer”: Architecture that breathes
In his famous work Tsurezuregusa (Essays in Idleness), the 14th-century monk Yoshida Kenkō wrote:
“A house should be built with summer in mind. In winter, one can live anywhere, but a poorly ventilated dwelling is unbearable when it is hot.”
Traditional Japanese architecture is a masterpiece of passive bioclimatism:
- Raised houses: Wooden structures rested on stilts to allow air to circulate under the floor and insulate from soil humidity.
- Removable walls: The sliding doors made of mulberry paper (shōji) and fabric (fusuma) were completely removed in summer, transforming the house into an immense pavilion open to the four winds.
- Sudare blinds: Suspended from the eaves, these bamboo blinds blocked direct sunlight while letting the slightest breeze through.
The art of perceived coolness: Rituals and nomadic objects
Unable to lower the thermometer, the ancient Japanese developed the science of “psychological” and sensory coolness, a typically Wabi-Sabi concept where the mind dialogues with the environment.
- Uchimizu: The millennial gesture of sprinkling water on the ground in front of one’s house at the end of the day. As it evaporates, the water captures the heat and instantly lowers the air temperature by a few degrees.
- Furin: These small glass or cast-iron bells suspended from windows. Their crystalline chime, triggered by the breeze, recalls the sound of water and sends a cooling signal to the brain.
- Sensu (the folding fan): More than a simple accessory, the traditional fan made of bamboo and washi paper was the ultimate individual air conditioner. Lightweight and retractable, it allowed one to create their own draft with an elegant flick of the wrist.
From the modern furnace back to the roots
Today, the landscape has changed. In Tokyo or Osaka, salarymen in suits brave the burning concrete to rush into offices and subways kept under a drip of aggressive air conditioning. Thermal shocks are violent, and the disconnection from nature is total.
This situation echoes what Europe is currently experiencing. Faced with repeated heatwaves, the temptation of “all-air-conditioning” is strong, but it proves to be energy-intensive and destructive to the environment.
What if the solution lay in a return to a more conscious coolness? Slowing down the pace, accepting the murmur of summer, and adopting simple, sustainable gestures.
