At Iidaka Kannon Temple!

Before you enter the temple itself, you have to wash your hands and the same way as cleansing the minds...
There's a store that sells small wooden card where you can write your prayers and wishes to be tied at the big board like the one I just did in the picture.
The sand ripples around the stone at the picture says that no one is allowed to step on that sand near the sacred stone.
There are small gongs hanging with long ropes and a long wooden beads also hanging in the middle of the temple where believers gently pull it as they whisper their prayers...
