According to various survey results, even in Japan, a few percent are said to be sexual minorities.Prohibition of discrimination against sexual minorities has become a major social theme, such as the promotion of "prohibition of discrimination based on sexual orientation and gender identity" based on the Olympic Charter and personnel rules of national civil servants. In recent years, the use of toilets based on sexual minorities, especially gender identity, has become an issue.In public spaces used by an unspecified number of people, some movements such as installing unisex toilets are progressing, while in office toilets used by acquaintances, men and women simply depend on their understanding of the surroundings and the presence or absence of coming out. There is also a problem that cannot be solved simply by providing a shared toilet.

　Therefore, the study group values ​​not only the voices of sexual minorities who find it difficult to use the toilet in the workplace, but also the voices of many others, and by multiplying the knowledge of the three members of the study group, "For all genders" It is said to pursue "the office toilet that should be".

　Associate Professor Takeyoshi Iwamoto of Kanazawa University, who chairs the meeting, said, "Based on the situation and efforts in various workplaces, a safe and comfortable toilet for people of all genders will become a society from both aspects of toilet space and users. We aim to spread it. "
