The Air Conditioning Jacket Keeps Japanese Workers Cool.

Japanese workers working in an overheated environment find new ways to keep cool while the summer temperatures are soaring.

They put on jackets with built-in air-conditioner fans.

The current Fukushima nuclear crisis has promoted the sale of Japanese cooling clothing, which is regarded as a kind of cooling clothing.

For example, a cooling jacket produced by Kuchofuku Limited has two fans running on a lithium ion battery pack.

After one charge, the battery can last up to 11 hours, so it consumes much less energy than the normal air conditioning system.

The jacket breathes 20 litres of air per second, and the air circulated from the inside of the garment.

"There is no need to cool the whole room," Kuchofuku President Hiroshi Ichigaya said.
