Noh, a classical Japanese musical drama that began in the 14th century, emphasizes subtle emotion and spiritual themes, often influenced by Zen Buddhism. The plays feature male actors who wear masks and are skilled in miming and dancing, with a central focus on the dynamic between a restless spirit (shite) and a bystander (waki). Seami Motokiyo, a key figure in Noh's development, contributed significantly to the genre and created well-known works such as 'Atsumori,' which reflects on themes of guilt and redemption following a historical battle.
