Dating back to the Momoyama era (1573-1596), jars were buried under the Noh stage in Nishi Hongwanji Temple in Kyoto, which is registered as a national treasure today. The jars were placed on an angle with the mouth facing up, in such a way that it increased the acoustic effect because the sound on the stage resonated in the jars.
By the Genroku period (1688-1704) during the Edo era, the acoustic technique had been improved by for example seeking better alignment of the jars and hanging jars in the holes under the stage.
Even today, many Noh theaters place jars under the stage.
