There is a traditional dance in Japan. That name is ''Yosakoi.'' It's one of the Japanese classical dance. Yosakoi have started from 1990, and spreded as proup dance with Yosakoibusi and Soranbusi. When we dance Yosakoi, we hold and sound clappers which are similar to castanet and said ''Naruko.'' As the history of Yosakoi, Takemasa Eisaku :he made Yosakoibusi thought that we must dance with anything to oppose to ''Awaodori'' at Tokusima. Then, he decided to dance with Naruko (a tool used to frighten birds) that is unique to Tosa, where rice is harvested twice a year. Nowdays, many children have danced at Sports day and other events.
