Family of five found dead in Japan
The five are believed to have died of carbon monoxide poisoning after burning charcoal pieces inside the vehicle, a rather common method of taking one's own life in Japan.
"We are investigating the case as a possible family suicide as they have also left a suicide note," the police spokesman said.
Japan, with a population of about 128 million, has one of the world's highest suicide rates, according to the Organisation for Economic Co-operation and Development.
Every year more than 30,000 people take their lives in a country where suicide carries less of a stigma than in some western nations.
