There has been a debate in appropriateness of legalization of death with dignity and euthanasia in Japan. To clarify views about these issues, we conducted a large nationwide study of the bereaved whose family member died at palliative care units. The percentages of 429 bereaved family members (response rate 65%) who affirmed legal authorization were 52 for death with dignity and 45 for euthanasia and who affirmed assignment at the discretion of the physician involved were 37 for death with dignity and 38 for euthanasia. In conclusion, views about legalization of death with dignity and euthanasia among the bereaved are inconsistent. No consensus is reached as to legislation of these issues.
