Okina , a ritual play without plot, a collection of old songs and dialogues interspersed with dances, can be seen in many parts of Japan, performed in various versions. In village festivals, it may be put on by local people using libretti derived from oral traditions, and in larger shrines professional players might be employed to perform it at the New Year. Puppets enact Okina dances at the start of Bunraku performances and Kabuki actors use them to open their season. Such Okina performances derive from Nō traditions, and as might be expected, the Nō schools have their own Okina, based on texts deriving from the Edo period, which they perform at the start of celebratory programmes. These ‘official’ versions feature, among other roles, two old men: Okina and Sanbasō (). Before the fifteenth century, when Nō traditions were being established, it was common for a third old man known as Chichi no jō () to appear as well (I shall refer to this ‘complete’ form as Shikisanban, three ritual pieces, a term used by Muromachi performers). These old men are marked out from all other Nō roles by their use of a unique type of mask, having a separated lower jaw connected by a cord (the so-called kiriago).Erika de Poorter, in her introduction to Okina, suggests that actors dropped the third section because its Buddhist content conflicted with a trend away from Buddhism towards Shinto (a trend she refers to as ‘the spirit of the times’). She supports her theory by adducing a similar ideological shift in contemporaneous interpretations of Okina and legends about the origins of Nō. De Poorter tells us little about these interpretations, as is perhaps appropriate for an introductory essay. This study, however, aims to give a full account of them, starting with a Buddhist reading, recorded near the beginning of the Muromachi period, proceeding to interpretations current among performers in the fifteenth century, and concluding with the purely Shinto explanation taught by the Yoshida lineage in the mid-sixteenth century.
