A Japanese lesbian couple plan to stage wedding photos in every country around the world where same-sex marriage is legal, in a push to increase understanding of LGBT communities at home, they said on Wednesday.

Students Misato Kawasaki, 21, and Mayu Otaki, 22, hope to give other LGBT people confidence in their identity and raise awareness of issues such as the lack of equal marriage rights in Japan.

"Through this project, I want to cheer up a lot of people (and say) that there is nothing to be ashamed of just because you are a sexual minority," Otaki said.
