Suikin Kutsu

In Japan, some gardens have a device that makes sound when water is given. This device is called "suikin kutsu", means musical pot.
The pot in picture is not musical water pot. That pot is just for supplying water,
Real musical water pot is under the ground. When water goes under ground, some sound is from under ground. Bamboo in the picture is for listening the sound.
