The Department of Intangible Cultural Heritage has been recording the ban-utai of Master Imai Yasuo, the eldest Noh actor to perform in a Hosho style, since 2005. This September, the 100th ban-utai was recorded. The repertory of Hosho-style Yokyoku includes 210 pieces, and the major numbers have been produced a record. The memorable recording of the 100th Noh-song “Higaki” was a secret piece of music in the penetrallia which was not played as Noh, but only the utai was handed on. Mr. Imai, who is 90 years old this year, sang quietly in a straightforward manner, performing this song about a beautiful shirabyoshi (dancing girl), who grew older, fell on bad times and made a confession before a Buddhist monk. Passing on the collective recordings of Noh-songs sung by a Hosho-style Yokyoku master in the late Showa Period has a significant meaning. The plan is to continue this recording a little more.
