48 year old Hideko Shimamura shows the last email from her late husband, Masayoshi, in Saitama on her mobile phone. He committed suicide in 2009, from depression brought on by excessive overwork. She says, "He called me and said 'I took eleven pills and I'm burning coal briquet but I don't feel sleepy yet.' He called me again later and said, 'I started feeling sleepy finally and becoming unconscious.' The phone was disconnected again. That was the last words from him."
