NextBit, an IT services provider, has equipped two strategic bedrooms, one for men and the other for women within its headquarters in Tokyo, equipped to prevent noise and allow employees to sit on their sofas for a while without disturbance, and not to carry phones, tablets or laptops inside.

"Siesta can significantly contribute to improving a person's efficiency, like balanced diet and exercise," said Amiko Sumikawa, a board member of the company, told Kyodo.

The company also asks its employees to leave work by 9 pm and refrain from overtime hours, which were blamed for causing increased Karoshi injuries or death from overwork.

According to the newspaper "The Guardian" British, the emerging technology companies are the fastest in dealing with "sleep deprivation" among employees, especially the fast-paced and unproductive, noting that the epidemic of insomnia costs the Japanese economy about $ 138 billion annually.

Credit also gives financial incentives to its employees to persuade them to avoid overtime and go to bed at a reasonable time.

The company, which works in the planning of weddings, rewards employees who sleep 6 hours a night with points that can be replaced by food inside the building's coffee shop. They use an application that monitors their sleep. Employees can score up to 64,000 yen (458 pounds).

According to a survey of fitness monitors in 28 countries, the Japanese slept six hours and 35 minutes a night, 45 minutes below the world average.
