30 year old Syota Nakahara, a former systems engineer, has been suffering from depression for six years, which was caused by excessive over-work, deprivation of sleep and stress. He sued the company for unpaid overtime and won the lawsuit in 2006 but he is still not able to return to work. Syota says, "I used to come to work by 8.40am and worked all day until 3am or so. After work, I bought snacks at a convenience store and finished eating in five minutes, took a quick shower, did some laundry, and went to bed for a few hours. I worked like that about a year and half, and eventually became ill." .
