Before you enter a shrine in Japan you should purify yourself with the water fountain.
That fountain is called ‘temizuya’ or ‘chozuya’ / 手水舎.
There are often ornately decorated taps with bamboo ladles to spoon the water.
Some are much more simple.
The procedure is the same:
Take the ladle at the purification fountain – fill it then rinse your left hand. Fill it again then rinse your right.
Then pour some water into your hand and put it into your mouth from your now-purified hands.
Rinse your mouth and spit the water out just beside the fountain.
Now you’re ready to go!
