The author presents data on suicide in Micronesia during the 1920s & 1930s when the area was governed by Japan. Japanese records reflect 241 suicides from 1922-1939. The principal cause of suicide, for both the indigenous population & the Japanese, was melancholy or weariness with life. However, there is no evidence to suggest that the frequency of suicide & suicide attempts or the methods used by the Japanese had any influence on the frequency & methods used by the islanders.
