As part of the project entitled “Study of Conservation and Utilization of Intangible Cultural Properties,” the Department of Intangible Cultural Heritage conducted an interview, on November 12 at the dressing room of the National Bunraku Theatre (Osaka), of Tosha Shusaku and Mochizuki Tamekichi of the Mochizuki Tamekichi School that has been engaged in the performance of hayashi music for bunraku since 1963. Both gentlemen are veteran performers, Tosha Shusaku of the fue, mainly, and Mochizuki Tamekichi of instruments other than fue. They spoke about very interesting topics associated with hayashi music, a very important part of bunraku that supports it from behind the scenes and that has not been noted so much until now. These included the changes in hayashi music and matters related to the training the hayashi musicians undergo. We are grateful for their having spared the time in the midst of their busy schedule in order to speak to us.
