Over 25% of Japanese in their twenties have thought of committing suicide, says survey.
The survey found that 28.4 of respondents in their twenties had contemplated suicide, the highest of any age group, while 36.2 percent of that group had considered taking their own life in the past year, according to the report.
Advertisement"The data show that the younger people hesitate to talk to others, or cannot find anyone to talk to when they have a problem because of shallow relationships with others," said the survey conducted by Japan's Cabinet Office.
"They tend to suffer alone," it added.
Overall, 23.4 percent of the more than 2,000 adult respondents said they had thought of committing suicide, up 4.3 percentage points from the previous and first such survey conducted in 2008.
The ratio stood at 27.1 percent for women and 19.1 percent for men.
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.
More than 30,000 people take their lives annually in Japan amid rising unemployment, with family troubles and health problems also cited as key factors behind many of those suicides.
