This study examined the effects and problems of learning about gender diversity by sexual minority parties for university students. The subjects were 102 university students in 10s and 20s. Quantitative and qualitative analyzes were conducted based on questionnaire surveys conducted before and after the 70-minute lecture by sexual minority parties. Regarding the awareness of LGBT among the subjects, 88% of the respondents "know the content" and 0.1% "did not know". The degree of awareness of SOGI was 5% for "know the content" and 90% for "did not know." The following question items were significantly different before and after the lecture. "I think love and marriage are between men and women.", "I think it's natural to like the opposite sex.", "Intuitively imagine a woman as a male partner and a man as a female partner if you have a lover.", "I don't care if an LGB person is in a friend", "I don't mind having an LGB person in my family.". This change indicated that the latter became more receptive to sexual diversity than before the lecture. As a result of the free description, before the lecture, there were descriptions such as "I look special" and "I have nothing to do with myself". On the other hand, after the lecture, there were descriptions such as "respect for the individuality" and "no sense or frame is taken for granted". From the results of this research, it was considered that the lectures by the parties would be effective as a clue from the perspective that "everyone is a person with diverse gender". This study did not examine how the changes in consciousness and attitude that occur after the lecture would be sustained or changed in the subsequent daily life. Examination of such long-term changes is considered to be a future task.
