The SFX made illusions of realities.

This stage has a 'flower way' under the influence of Noh. There are devices such as a rotating stage underneath the stage, and stages that can be elevated (Seri Agari) or lowered (Seri Oroshi), which originated in puppet plays. 'Keren', a style of acting, would not exist if it weren't for such devices.
This is 'Seri Agari' at the flower way of 'Sendai Hagi'. The stage with the actor on it is elevated with a rope from under the floor.
