Marihan Yamamoto, the leader of the Sign Language Dance Unit Smile×Ring, wins the Miss Teen International 2023 Grand Prix, a 10s miscon test. In July 2023, he participated in the World Competition. Yamamoto taught a dance event and asked hearing-impaired people to “I’m getting your dance well” to create a dance that incorporates sign language, and to make many people smile. I invited my classmates to create a sign language dance unit. Currently, he is engaged in activities to promote sign language dance while carrying out the activities of models and talents.
