Shrines
Shrines in Japan can be recognized by the large Tori gates shown in the picture for the Shinto religion. Japanese will often bow before entering, maybe even clap. Please visit shrines as they are wonderful experiences and you are welcomed as a foreigner. Do not enter the Tori gate directly through the middle as that is where the Gods are said to pass. Simply offset slightly to the right or left when passing through. It is common to approach the Shrine itself and throw a 5 yen coin (the only coin with a hole in the middle) for good luck. You can throw more however 5 cents or 100-yen coins are normally acceptable
Temples
Buddhist Temples are different than Shinto Shrines. You will typically see Buddhist statues or small horns at the top of the temple and are welcome here as well. Buddhist temples in Japan hold profound cultural and historical significance. With roots dating back to the introduction of Buddhism to Japan in the 6th century, these temples showcase exquisite architecture, serene gardens, and valuable religious artifacts.
Religious Etiquette
If there is water and a small ladle on the grounds, please take it, scoop some water into it, and pour water over your hands AWAY from the fountain - over the ground. First over your left hand, then your right hand. Then pour more water into your palms to bring to your mouth to swish in your mouth and spit on the ground. This ensures you are clean before entering.
It is custom to clap and bow before entering a tori gate, and to pass to one side of the tori gate - as the middle is for the Gods. You may also see Japanese clap and bow prior to throwing money into the collection box. Some temples will have a bell you can ring as well. This is to let the Gods know you have arrived.
Omamori Charms
Omamori are good luck charms you can buy at shrines and temples. They each represent something specific such as driving safety, pregnancy, finding love, etc. They are each unique to temples and can be very fun to collect. Most people place these on backpacks or purses to carry them with them or purchase them as gifts for friends and family.
Fortunes are also often available for purchase. Please tie your bad fortunes to the fence, and keep your good ones. Use a translate app to help you!
