In Kurokawa community at the foot of Mt. Gassan in Yamagata, people have inherited precious folk art for more than 500 years. It’s the Kurokawa Noh play. Between 2 groups, Kami-za and Shimo-za, about 230 people are involved. It’s a large-scaled play as a folk art with 230 Noh masks, including some from 500 years ago, as well as 540 Noh programs and 50 programs of Kyogen, the traditional comedy. It is also known to be precious Noh since they still keep the old programs that are no longer performed in the central theaters. Noh as Shinto rite is performed 4 times a year at Kasuga Shrine. We follow the play that was dedicated to the shrine during the autumn harvest festival.
