Kenshibu
Kenshibu is a category of Japanese interpretive dances performed to traditional music accompanied by poetry known as shigin. Kenbu refers to dances performed with the aid of a sword, and shibu to dances performed with one or more fans. While fans may also be employed in some kenbu dances, not all require them.
History
Although Japanese kenbu existed since the Nara and Heian periods of Japanese history, and exist in Shura Nogaku, the modern kenshibu is an invention of the post-Meiji era.Kenshibu draws its origins from the Gekken Kaisha created by Sakakibara Kenkichi in 1872. The Gekken Kaisha toured Japan, engaging in 'fencing performances' which quickly became popular. Many modern schools of kenbu derive from other traditions, but Sakakibara's Gekken Kaisha was the first to explore the form.
Following the end of World War II, swords were outlawed in Japan for a period of about seven years. During this time, kenbu schools adopted the use of fans instead of swords in their dances. After swords became legal once again, this new type of dancing was retained. Over time shibu has evolved into a style distinct from kenbu, with its dances set to poetry of a less martial character.
