About 70 percent of sexual minorities have experienced bullying in school and 30 percent have thought about committing suicide, according to a survey of lesbian, gay, bisexual and transgender people.

The survey on the school lives of LGBTs, the first large-scale study undertaken in Japan, found that 68 percent of the 609 respondents experienced bullying in elementary, junior high or high school.

Among them, 53 percent were verbally abused and 49 percent were ignored or excluded from groups. Some 20 percent experienced physical bullying and 11 percent suffered sexual abuse, such as having their clothes taken off by classmates, according to the report, released Wednesday.
