Why is the rehearsal period so short?

By the standards of modern theatre, a month or more of rehearsal for a single play is unremarkable. Against that, kabuki's rehearsal period is startlingly short. Half the reason is the shape of the business: at theatres like the Kabukiza, both the bill and the company turn over monthly. The few days between one month's senshūraku and the next month's opening are the whole of the time available — and several plays must be raised inside it.

The other half lies in what rehearsal is for. In the classics, the actors, the musicians and the crew handling scenery and properties all already hold the play's kata as a shared language. The pauses in the dialogue, where a mie is struck, when the tsuke sounds, how the curtain opens and closes — the broad shape is settled, and does not need inventing. The work is not to build from zero but to tune what is already in each body to the dimensions of this particular company.

Rehearsal therefore turns on adjustment: so that is where your house takes the pause — then I will wait a beat. The same play breathes differently when the actor opposite changes. It works in a short window because the shared ground is enormous, not because little preparation is needed. That ground has been laid over decades, beginning in childhood.
