When visiting a jinja, pass under the Torii (sacred gate) and proceed to the Temizuya (purification font usually consisting of a stone water basin) to cleanse your hands and rinse your mouth. This is a simple act of purification before approaching the main sanctuary.
Temizu (How to purify your hands and mouth)
1. Take the dipper with your right hand and fill it with water. Pour some water over your left hand to rinse it.
2. Shift the dipper to your left hand and rinse your right hand.
3. Take the dipper with your right hand again, and pour water into your left cupped hand and rinse your mouth. Please do not touch the dipper directly to your mouth.
