Darkness as a sacred place

Japan's traditional culture has a peculiar sensibility that finds charm (omomuki) precisely in "shadow," unlike a bright, glittering beauty. Junichiro Tanizaki once wrote, in his essay In Praise of Shadows (陰翳礼讃, 1933), "Beauty lies not in the object itself but in the patterns of shadow, the light and dark, that one object makes against another." As a jewel lit by night light gives off its radiance only in the dark and loses its charm when exposed to the light of day, he pointed out, beauty cannot stand without shadow. In Praise of Shadows is still read as a masterpiece, but what lay behind the Japanese nurturing a culture that takes shadow as beauty?

The beauty of shadow that everyone thinks of first is the traditional lighting of the Japanese house, with ingenious touches here and there that use shadow skillfully. By day, for example, the washi paper of the shoji screen diffuses sunlight softly and brings a dim brightness into the room, while at night only weak lights such as the andon lantern and the candlestand light the room, and shadows arise naturally in its corners. In a Japanese-style room refined over long years in such surroundings, it was once even hesitated to hang a bright light from the ceiling. The Japanese of today dislike shadow and think only of making everything bright, but this too is an effect of the loss of the Japanese house and of the shape of the home changing greatly after the war, tied to the age of mass production. This is not simply a matter of houses: in that it changed the very base of the Japanese structure of mind, it will someday be taken up as a great problem.

In fact, in the design of a Japanese-style room, ceiling light is often deliberately avoided, indirect light is set above the tokonoma alcove and a small andon-type light placed on the floor, to create "moderate shadow" in the room. The contrast of soft light and shadow through the shoji gives the viewer's heart deep peace and brings a quiet beauty to the space. The hanging scroll and flower arrangement in the tokonoma, too, can convey no charm at all in strong direct light, and their charm stands out only in modest light and dark, giving off the beauty of yugen. I feel this myself when I visit a traditional Japanese room now and then, and it is truly an element of Japanese beauty. At the main tourist places now, though, this beauty of shadow has been lost, and since everything is made bright, Japanese beauty is not used and culture is instead greatly lost, which troubles me. That is because I think it bears not only on houses but on Japanese beauty in general, and even on faith.

The aesthetics of darkness can be seen in shrine architecture too. The main hall, where the gods are enshrined, is a sacred realm, and its doors are normally shut fast, so one basically cannot enter the main hall of a shrine. But when one now and then gets the chance to enter, the inside of a main hall, with outside light shut out, is a deep darkness, and one feels that the god is believed to rest there. Since ancient times there have been many Shinto rites performed in the dark of midnight. The best known is the daijosai, held only once for a newly enthroned emperor, but also in the "Senko no Gi" of the famous Kasuga Taisha in Nara, when the divine body is moved in complete darkness with every light put out, some hundred priests surround it and move along the pitch-black approach raising a strange cry. This is not mere darkness but the concept of "joan" (浄闇), pure darkness, which comes from the faith that "darkness is the realm of the pure gods."

That is, it tells the Japanese value that takes darkness not as simply ill-omened but as positive and mysterious. In fact, when I went to the "Kamimukaesai" of Izumo Taisha, I saw closely the rite of welcoming the arriving gods on the beach at night, and the only lights were the bonfire, torches, and the moon. In the dark, visionary darkness one hears only the sound of waves breaking and the sound of the flames. In that deep "pure darkness" the priests welcome the visiting god, and from there go into Izumo Taisha, where too a glimpse of ancient Japan seemed to come with only a little light. One feels the mystery in the depths of the main hall wrapped in dark, and because it cannot be seen directly, its sanctity stands out all the more. The Japanese held awe toward such darkness and kept the air of the sacred ground.

It is the same in Buddhist temples. In temple architecture too, it was once usual to give mystery to a Buddhist image by the staging of light and shadow. In the main hall of Joruri-ji in Kyoto, founded in the Heian period, the space where nine Amida Nyorai are enshrined receives only faint natural light through the shoji, and the hall is kept dim even by day. Since artificial lighting is held to a minimum, a visitor for a while looks into the dark at the central image faintly rising into view. As the eyes gradually adjust and the figure of the Buddha grows clear, one is struck by its solemnity and mystery. A golden Buddhist image rising in dim light, unlike one seen in strong light, seems to carry somehow a spirituality beyond this world. The philosopher Tetsuro Watsuji, in his Pilgrimages to Ancient Temples, described the harmony of the dim light of the Joruri-ji main hall and the golden Amida faintly shining at its center as "a great, quiet symphony of color, light, air, and line." Truly a stage woven of light and shadow has set the Buddhist image apart as a being not of this world, and has called forth deep reverence in those who join their hands before it.

Such splendid temples are now few, but if one wants to feel personally the mystery toward the Buddhist image that comes from the beauty of shadow, I recommend the main hall of Shin-Yakushi-ji in Nara, along with Joruri-ji. Both temples are splendidly designed to hold light to a minimum, a space on another plane from famous shrines and others that pour in great quantities of artificial lighting. Only in such temples can one feel how the ancient Japanese felt the mystery of the Buddhist image.

What the Japanese attachment to shadow comes from at the root is unknown, but the influence of the thought of yin and yang from ancient China can be pointed out. In the Heian period especially, onmyodo came to be valued at court, and here a new worldview spread that took all things as two, "yin (kage, shadow)" and "yo (hikari, light)." The thought of yin, yang, and the five elements deeply affected not only rules of life but the sense of beauty, and a sensibility was nurtured that values the harmony of two sides, front and back, light and dark. As Japanese aesthetics is often said to "make one feel emotion on the reverse side of the unity of front and back," there is a tendency to find feeling not only in the visible radiance of the front but in the shadow behind it. So from before the Heian period, in Japan there were almost no poets who sang the sun, while many sang the moon in waka and haiku. And the moon that moves them is not the full moon but a waning one, the new moon and the like, with little light, and many poems sing not the moon itself but a pond or lake faintly mirroring the moon's light.

Put another way, these express the feeling and sensibility "beautiful because it is lacking," and resonate with the thought of yin and yang. In fact, Shogun Yoshimasa Ashikaga of the Muromachi shogunate built Ginkaku-ji (1490) to enjoy the moonlight, but it is said that he felt refinement in the moon of the thirteenth night, a little short of full, more than in the full moon of the fifteenth. A sensibility that finds beauty not in perfect brightness but in half-brightness, a state mixed with shadow, has been engraved in the Japanese heart since long ago. I think Ginkaku-ji also reflects the budget shortage of the Ashikaga's decline, but even Kinkaku-ji (1397), built by his predecessor Yoshimitsu Ashikaga, is notable for being designed with high skill so that stillness and shadow drift in it, avoiding showiness though it uses gold.

I mean also to discuss tea rooms later, but if you begin by understanding that the sense of "taking shadow as beauty" runs through architecture, art, and thought everywhere in Japanese culture, I think a trip to Japan becomes much more meaningful. The air of a Japanese room woven of pale light and shadow through the shoji, the solemn presence of a shrine's main hall sunk in dark, the noble look of a Buddhist image raised in dimness by a single shaft of light into a hall, all hold a deep feeling and lingering resonance that brightness alone cannot give. Behind it there must have been a conviction that true beauty appears precisely in the contrast of yin and yang, of light and dark. In modern life, lighting is rich and the tendency to drive out darkness has grown strong, but if you suddenly lower the light and put yourself in the quiet of shadow, you may feel the breath of a tradition that pulses in the Japanese sense of beauty.

Where there is light there is shadow. The beauty of shadow that Japanese culture nurtured speaks quietly to us of the importance of harmony and deep feeling.

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 )

In Takahiro Mitsui's own words: “The Nihon Shoki tells the road to Ise in linear time, while the Kojiki places Ise in nonlinear time, as a place decided since the Age of the Gods.” (Project 2049 Vol.4, https://project-2049.takahiromitsui.com/vol-4 )
