9. SOUNDBITE (Japanese) Atsushi Mizutani, 47-year-old construction site worker:
"The difference is significant (with and without the airconditioned jacket). How can I put this… The way fatigue builds up. I used to struggle from the heat after work, and still felt hot when I got home. Once the air-conditioned jackets were introduced, I feel less tired after work."

14. Director at SFT Laboratory, Takeo Kurumizawa, who designed the first airconditioned jacket for Kuchofuku, showing the jacket, UPSOUND (Japanese) "The breeze sent by the fan blows into the jacket and runs along the body."
15. Wide of Kurumizawa switching on the air-conditioned jacket, UPSOUND (Japanese) "The air goes up the neck and leaves from the neck and the sleeves. It evaporates the sweat, which cools down the body."
16. SOUNDBITE (Japanese) Hiroshi Ichigaya, CEO of Kuchofuku:
"We somehow managed to make one despite all the water leakage from the piping. Once I tried it, I felt my body temperature went down, but couldn’t stop the water leaking from the pipe connectors and my trousers were completely drenched."

18. SOUNDBITE (Japanese) Hiroshi Ichigaya, CEO of Kuchofuku:
"There was no way we could sell that product. Then I realised our body contains of plenty of water and conveniently without using any pipes, we are covered with sweat glands. Our brain senses that the temperature is hot, it instructs the sweat glands to secrete sweat. This natural cooling mechanism for our bodies to cool down as sweat vaporizes, was the thinking behind the development of ‘kuchofuku’ (air-conditioned jackets)"
19. Pan of fans and filters
20. Zoom into catalogue showing the effect of kuchofuku, how body temperature dropped after 10 minutes usage. The red portions of the image indicate higher temperatures. After 10 minutes with the fan switched off (left); switching the fan on for 10 minutes (right)

21. SOUNDBITE (Japanese) Yasufumi Miyake, emergency medicine advisor:
"I think it (referring to air-conditioned jacket) is a must-have item. What else do we have in order to cool down the heat we feel, while working without having both of our hands blocked? We can cover ourselves with ice packs but they are heavy and won’t last for long. On other hand, that (referring to air-conditioned jacket) is effective until the battery dies."
