I'm a London-based artist and last year I visited Japan in order to research 'contemporary butoh'. I managed to do some great interviews with some of the first generation Butoh artists as well as younger ones. I'm keen to share this information as it is a fascinating body of ideas surrounding Butoh, it's origins, it's definitions and it's future.

I would ask you to please contact me for permission to use any of the material you might find. Thanks
