1. What the Torii Gate at a Shrine Entrance Marks
The torii gate standing at the entrance of a shrine marks the boundary between the everyday world and the sacred space where the deity resides. It is said to represent the meaning "sacred ground begins here" [6]. When passing under a torii, the basic etiquette is to bow your head slightly as you walk through [6].
Some shrines have multiple torii gates lined up along the approach path. The one closest to the entrance is called the "first torii," and as you move deeper, they are counted as the second, third, and so on. There is a belief that the sacredness increases as you pass through each gate [6]. Various theories exist regarding the origin of the torii itself.
Thick ropes made of straw, called shimenawa, are often hung under the eaves of torii gates and main halls. These ropes indicate that the place is holy and pure [7]. They have loose ends hanging down and are decorated with paper strips called shide. While they are commonly seen on main halls, they are also frequently found on torii gates [7].
The torii and the shimenawa mark the boundary, while the bow signifies the start of the visit. The next place you encounter is water, which serves to purify your hands and mouth within this sacred boundary.
2. Why People Wash Their Hands and Mouth at the Temizuya Water Basin
Inside the shrine grounds, there is a structure with ladles called a temizuya (or chōzuya). It is used to wash hands and mouth before approaching the main hall. The pronunciation of "temizuya" varies by shrine, such as "chōzuya" or "temizusha." This practice of cleansing the body with water is said to be similar to rituals performed in rivers or the sea [5].
The steps are quite specific. According to the Japan Tourism Agency’s multilingual database, you use a ladle to scoop water and wash your left hand first, then your right. Next, you cup some water in your left hand to rinse your mouth, and then wash your left hand again. Finally, you turn the ladle upright to let remaining water clean the handle before returning it to its place [8].
There are important cautions. You should not put your mouth directly on the ladle, nor should you throw coins into the water basin [8].
The word "senshin" (washing the heart) is often carved into the stone water basin. This suggests that by cleaning your hands and mouth, you are also purifying your mind [5].
However, details such as how to dispose of the rinsed water vary depending on the shrine or source. If you are unsure, it is safest to follow the specific instructions provided at that shrine.
3. How Offerings in the Offering Box Changed from Rice and Fish to Money
Putting money into the offering box has a different meaning than paying for goods. According to the Japan Tourism Agency, the offering box is a relatively new addition to shrines. Previously, people offered rice and other gifts from the sea and land to the deity. As currency became widespread, money began to replace these items [9].
The character "sai" in "saisen" originally referred to visiting a shrine or temple to give thanks for a wish being granted. In the past, there was a custom of offering hatsuho, which were first harvest rice ears or fish [10].
By the late 8th century, examples appear where coins were used instead. The term "sansen" appears in documents from the early 16th century, and the word "saisen" appears later in that same century. This change reflects the development of a money-based economy [10].
Therefore, money offerings can be seen as a replacement for gifts like rice that were offered out of gratitude over time. However, this explanation does not state when offering boxes like today’s became widespread across the country.
4. Why People Ring the Bell and Clap to Call the Deity
After making an offering, you ring a bell. The sound of the bell is said to have the meaning of purification and calling upon the deity [5]. The subsequent clapping is also explained as using sound to alert the deity to your presence and gain their attention [5].
When clapping twice, there is a custom of offsetting the fingertips of the right hand slightly lower than the left. The gap is about up to the first knuckle [5]. This movement is explained by the idea that the deity and the human are not yet united. By clapping twice, you invite the deity, and finally joining your hands signifies becoming one with them [5].
However, these meanings are described as "said to be," and various theories exist for each action [5]. There is not always just one fixed answer for a single movement.
If we accept the idea of calling out with sound, clapping serves as a signal in the quiet shrine grounds that you have arrived. If even the way hands are joined has meaning, when did these practices take their current form?
5. When the Two Bows, Two Claps, One Bow Pattern Became Standard
Among the movements discussed, the "two bows, two claps, one bow" pattern is particularly famous. The Association of Shinto Shrines explains that worship etiquette has undergone long changes, and now "re-bow, two claps, final bow" is the basic form [1].
According to an article citing the Association of Shinto Shrines, this pattern was gradually unified across shrines nationwide from the Meiji to Showa eras. Before that, etiquette differed from shrine to shrine [2]. This means it was not uniform since ancient times but standardized relatively recently.
There are different views on when it became common among visitors. Another article suggests that this practice did not spread widely until the Heisei era and may not have been very common during the Showa period. This is the author’s perspective [3]. The time of standardization and when it became common among visitors are not necessarily the same.
Some shrines still differ today. Izumo Taisha is said to have visitors clap four times, unlike other shrines [4]. The Association of Shinto Shrines states that there are no strict rules for basic etiquette [2]. When visiting, you should follow the guidance of that specific shrine.
Whether it is how to dispose of water or how many times to clap, the shrine’s own instructions come first.
6. How to Check the Difference in Clapping Sound Yourself
To understand the difference in sound, you can try clapping twice at home: once with fingertips perfectly aligned, and once with the right hand offset slightly. In actual shrines, consider those around you, so test this at home.
If you can visit a nearby shrine, check these things: How many torii gates are there? Which is the "first torii" closest to the entrance? Does the sign at the temizuya explain how to use the ladle or handle rinsed water? Are there signs about clapping counts or etiquette?
For official information, the Association of Shinto Shrines’ page on worship etiquette [1] and the Japan Tourism Agency’s multilingual database [8] [9] are useful clues. If shrines like Izumo Taisha have different customs, you might wonder what the rules are at your local shrine.
