To meet the sacred, first change yourself

Did you know that worshiping at a shrine is not something to do whenever you feel like it, but needs proper preparation? The Japanese of today too have forgotten such old manners, but for worshiping at Izumo Taisha in Shimane Prefecture on this trip, I made "a certain preparation" and worshiped this morning. It was "three days without meat." Hearing this, readers may think of Buddhist influence, but in fact Shinto has such a manner too, so this time I will look at it from my own experience.

Around Izumo Taisha, one of the oldest shrines, several customs of purifying oneself beforehand for worship are handed down. One is the teaching to "refrain from meat from three days before worship": concretely, to eat no meat for the three days before visiting Izumo Taisha and to keep to plain, abstinent meals. This "meat" is set especially as that of "four-legged beasts," and the people of Izumo have kept it since long ago.

In Shinto, eating meat is tied to taking an animal's life and touches its blood and death indirectly, so it was believed to bring a "kegare (穢れ)," a pollution unfit for standing before the gods. In Japanese Shinto the concepts of "kegare" and "imi (忌)" have played an important part, and merely understanding them gives worship at a shrine much more effect.

First, "kegare" refers to an unclean state, a stain of body and mind, a state in which spirit and vitality have grown weak. The typical example is the kegare of death. When a family faces a death, for example, the bereaved were thought to come into a state in which their "spiritual power (vitality)" has "withered" from deep grief. This is known in Japan as "kegare (穢れ)," which has the meaning of "ki withering." Since in the old days kegare was also thought to be an invisible force that spreads to others, Shinto gave rise to a custom called "kichu," in which the bereaved, for a certain period, cut off contact with the outside, keep quietly to themselves, and recover their spiritual power. During kichu the bereaved must refrain from worshiping at shrines and taking part in festivals, and devote themselves to purifying themselves. This was a consideration so as not to bring the kegare of death to others or to the gods, and an important custom for keeping the community going.

"Imi," on the other hand, refers to restraining one's conduct in a particular period or situation in order to avoid kegare. Imi is a taboo that individuals or communities set voluntarily, an attempt to keep purity by limiting what one does around oneself. Now that community has been lost, imi has a strong side as a taboo that an individual sets by himself. The kichu above is also imi in the broad sense, but in daily life too there are examples handed down in many places, such as the festival's person on duty living a life that avoids impurity before the festival. In festivals it has been believed that if those concerned neglect "saikai," abstinence, divine punishment or ill-omened events will occur. In the Shinto worldview, kegare is a negative state of "ki" that clings to a person for a time, and it was thought that to purify it a certain process of imi and cleansing is needed.

The concept that matters here is "shojin kessai." It refers to the Shinto practice of cutting off meat, alcohol, and lust and purifying body and mind by bathing and purification. "Shojin" and "kessai" were originally different concepts, but by about the end of the Heian period, since their meanings are close, they came to be used together. Behind the concept lie both "saikai," tied to Shinto rites since ancient times, and the "precepts" of Buddhist origin. That is, these customs were handed down to the present as a concept of their own, born of the "mixing of gods and buddhas" of Shinto and Buddhism.

In fact, in Japan, under the ancient ritsuryo system, the "Jingi-ryo" fixed rules of saikai to be kept before and after Shinto rites. There the period of saikai was set by the importance of the rite: a month of saikai for a "great festival," three days for a mid-sized festival, and one day for a small festival. That is, the tale handed down around Izumo Taisha above can be taken as the mid-level saikai among these.

Why, then, was giving up "meat" especially stressed in Izumo? The reason is that, as said, eating meat was thought tied directly to "kegare." To eat an animal's flesh is accompanied by slaughter and the sight of blood, and this was seen as an act that directly brings kegare. Meat also was said to give the body a raw, fishy ki, and does not suit the divine presence that values cleanness. Among them, the flesh of four-legged beasts, "cattle, horses, boars, deer," was also the killing of companions of daily life, and was taken as an important object of imi.

Personally I think the oldest representations of four-legged beasts for the Japanese were the deer and the boar. This is because cattle and horses did not exist in the Jomon and Yayoi periods, and because I think the Jomon had a custom of offering the boar and the Yayoi the deer to the gods at rites. Probably afterward, under the influence of Buddhism's arrival, the cow came to be made sacred and eating beef was taboo, but the source lay in the boar and deer, and I do not think that such Shinto customs are simply the influence of Buddhism (this, though, is the common view). Rather, the source of such customs was flowing in Japan from before Buddhism came, and it seems the right view that Buddhism then systematized them strictly.

In Izumo it is basically said to avoid four-legged beasts for the three days before worship, but more thorough people sometimes also abstain from fish (raw fish especially) and sake, and from this they spent several days on a menu without animal ingredients called "shojin ryori." The culture of shojin ryori tends to be thought of as coming from Buddhist precepts, but in the Shinto world too it came to be accepted as "a meal that purifies the body." We often see offerings made to the gods at shrines, and looking at the contents and arrangement of the offerings, and their importance, I cannot help feeling that this custom has, rather unexpectedly, an origin in a very old age. That is why I think it important that we think about worshiping at a shrine again from the historical side and prepare as far as possible according to old manners.

In short, giving up meat before worship is a bodily purification and at the same time one's own spiritual marking of a line. The act of cutting off meat urges in oneself the resolve "now I am to take part in a sacred act." By cutting off everyday desire in this way, it is a fact that it raises a reverent state of mind and puts one's posture toward the god in order. Today the custom of refraining from meat beforehand for ordinary worship has gone, people eat as they please and visit shrines at their own convenience, but the spirit carried by such old customs is still meaningful, and without keeping it, worship at a shrine is not only without effect but may even do harm.

So, to worship at Izumo Taisha once more according to old manners, I avoided four-legged meat for the three days before, spent that time drinking sacred spring water, put body and mind in order, and worshiped in the early morning. I had worshiped at Izumo Taisha many times, but today, having worshiped by the proper manner, I felt a strong spiritual power of the god unlike the usual. This was because I myself was ready to face the god, and conversely it means that going to a shrine without doing such a thing will not bring a great effect.

This discovery is important to me personally and is the key to seeing the sides of Shinto faith anew from many angles. It is almost ignored today, but in Shinto, only after making preparation to "purify" "kegare" as above can one first offer prayer to the gods. There may be the same in faith in many religions, not only Shinto, but faith is hard to put into words, and so it is hard for people living in an information society like today's to understand.

It was a worship at Izumo Taisha in which I became sure that the experience of being able to face the god only when one changes one's attitude toward the god will have a deep effect on my research from now on.

Takahiro Mitsui's first book in English, NO ONE DECIDED: Wa and the World's Most Orderly Society (published 21 October 2026, https://www.amazon.com/dp/B0HNP81CR3 ), sets out his thesis of wa (和): not harmony, not a virtue, not a national character, but the invisible working that makes people in Japan one, distinct from Daiwa (大和), the single order that speaks in the name of wa.

In Takahiro Mitsui's own words: “Wa is not harmony. No one decided, and yet it is decided.” (Project 2049 Vol.3, https://project-2049.takahiromitsui.com/vol-3 )
