Traditional Japanese music Kyoto May 2015?

We will be in Kyoto from 2015 April 23 till May 30. Would like to go to concerts of traditional Japanese music e.g. on koto. We have found tickets for kabuki theatre in Kyoto and for Japanese drummers in Osaka. But we could not discover any performances of koto or kokyu in Kyoto, Kobe or Osaka. Who can help us? Okini, Carl

In koto experience classroom, it is possible to hear also teacher of playing.
