陰翳の美：闇を清浄な神の領域とする感性Shadow Defines Japanese Beauty—Darkness as a Pure Divine Realm

Japanese traditional culture possesses a unique sensibility that finds charm (“趣”, omomuki) in “shadows” (“陰影”, in’ei), rather than in bright, glittering beauty. Jun’ichiro Tanizaki famously wrote in his essay In Praise of Shadows (“陰翳礼讃”, 1933), “Beauty lies not in objects themselves, but in the subtle interplay of shadows and light created between them (美は物体にあるのではなく、物体と物体との作り出す陰翳のあや、明暗にある).” For instance, he pointed out how precious jewels illuminated at night sparkle precisely because they are surrounded by darkness; when exposed to the harsh daylight, their allure fades. Tanizaki argued that without shadow, true beauty cannot exist. In Praise of Shadows continues to be read today as a classic, but what exactly is the historical and cultural background that has cultivated this Japanese affinity for shadows?

The beauty of shadows that immediately comes to mind can be observed in the traditional lighting environments of Japanese houses, where numerous ingenious methods are employed to skillfully harness shadows. During the daytime, “shoji” (障子, paper sliding doors) diffuse sunlight softly, providing rooms with gentle illumination. At night, rooms are lit only by subtle sources such as “andon” (行灯, paper lanterns) or candle stands (“燭台”, shokudai), naturally creating shadows in corners. In traditional Japanese rooms (washitsu) refined through centuries under these conditions, people once hesitated even to hang bright ceiling lights. Today’s Japanese dislike shadows and are obsessed with making everything brightly lit, a phenomenon that follows from the loss of traditional houses and the way post-war mass production changed how homes are built. This shift represents more than just a change in architecture—it fundamentally altered the Japanese psyche and will likely become a significant point of concern in the future.

Indeed, traditional Japanese room design intentionally avoids ceiling lights, frequently employing indirect lighting above the “tokonoma” (床の間, decorative alcove) and placing small lantern-style lights on the floor to create a “moderate shadow” within the room. The soft interplay of light and shadow filtered through the shoji brings deep tranquility to viewers’ minds, creating quiet beauty in these spaces. Decorative scrolls (“掛け軸”, kakejiku) and flower arrangements (“生け花”, ikebana) displayed in the tokonoma completely lose their subtle charm under strong direct lighting; they can only reveal their true allure within subdued illumination, thus evoking the aesthetic quality known as “yugen” (幽玄). Personally, whenever I visit a traditional Japanese room, I clearly sense this as an essential element of Japanese beauty. However, today’s major tourist destinations have lost this appreciation for shadows, instead excessively brightening every space, thereby severely diminishing Japan’s authentic aesthetic culture. This trend is troubling because it affects not only buildings but the broader spectrum of Japanese beauty and even spirituality.

For instance, Japanese shrine architecture also exemplifies this aesthetics of darkness. The “honden” (main sanctuary), where deities are enshrined, is considered a sacred space, and its doors usually remain firmly closed, meaning people generally cannot enter. On the rare occasion one does gain access, the interior—isolated from outside light—is a profound darkness that immediately evokes a sense of divine presence. Since ancient times, many Shinto rituals have been performed in deep darkness. One prominent example is the “Daijosai” (大嘗祭), a crucial imperial ceremony held just once during the enthronement of a new emperor. Another famous example is the “Senko no Gi” (遷幸の儀, ritual transfer of the deity) at Kasuga Taisha Shrine in Nara, during which, under complete darkness, around one hundred priests surround the sacred object (御神体) and move along pitch-black paths while chanting mysterious invocations. This darkness is not merely an absence of light, but is conceptualized as “joan” (“浄闇”, sacred darkness), stemming from a belief that “darkness represents a pure, divine realm (闇は清浄なる神の領域).”

In other words, it reflects the Japanese value system that perceives darkness positively and mystically, rather than simply as ominous. Indeed, I myself vividly experienced this once when attending the “Kamimukae-sai” (神迎祭) at Izumo Taisha Shrine. The ceremony began on a beach at night, welcoming the arriving deities with only bonfires, torches, and moonlight illuminating the darkness. Amidst this profound “joan,” the only audible sounds were the crashing waves and crackling flames. Within this mystical darkness, priests greeted the arriving gods and then guided them towards the main shrine. Even there, the minimal lighting provided just a fleeting glimpse into ancient Japan. Wrapped in darkness, the inner sanctuary of the shrine felt deeply mysterious, its sanctity heightened precisely because it remained hidden from direct view. It became evident to me that the Japanese have always revered such darkness, carefully preserving this sacred ambiance.

This concept similarly applies to Buddhist temples. Traditionally, temple architecture meticulously employed light and shadow to enhance the mystique of Buddhist statues. A prominent example is the main hall (hondo) of Joruri-ji Temple (浄瑠璃寺) in Kyoto, established in the Heian period, where nine statues of Amida Nyorai are enshrined. In this hall, minimal natural light softly filters through shoji, leaving the interior dim even in daylight. Since artificial lighting is deliberately limited, visitors initially gaze into the faint darkness as the central statue gradually emerges into visibility. As one’s eyes slowly adjust, the solemnity and mystique of the Buddha become increasingly profound. The golden statues, subtly illuminated within the dimness, feel imbued with a spiritual aura transcending worldly existence—something entirely different from their appearance under harsh lighting. The philosopher Tetsuro Watsuji, in his book Koji Junrei (古寺巡礼), or Pilgrimages to Ancient Temples, poetically describes this harmony of Joruri-ji’s subdued lighting and the softly glowing gold of Amida Buddha as “a great, quiet symphony composed of colors, light, air, and lines (色と光と空気と線との大きな静かな交響楽).” It is precisely this interplay of light and shadow that elevates the Buddha statues to something beyond the ordinary, evoking profound reverence among worshippers.

Today, such outstanding temples have become rare, but if one personally wishes to experience the mystique of Buddha statues born from the beauty of shadows, I highly recommend visiting Joruri-ji along with Shin-Yakushi-ji Temple in Nara. Both temples boast extraordinary designs with minimal illumination, placing them in a completely different dimension from famous shrines often brightly lit with artificial lights. Only in temples like these can one truly sense how ancient Japanese perceived the sacredness of Buddhist statues.

Although the precise origins of this Japanese affection for shadows remain uncertain, one influential factor likely stems from the yin-yang (“陰陽”, in’yo) philosophy introduced from ancient China. Especially during the Heian period, the practice of Onmyodo (“陰陽道”, Way of Yin and Yang) gained prominence within the imperial court, popularizing a worldview that interpreted the universe in dualities of shadow (“陰”, yin) and light (“陽”, yang). The yin-yang five-element theory (陰陽五行説) profoundly influenced not only practical living but also aesthetic sensibilities, cultivating an appreciation for the harmony between dual aspects such as front and back, brightness and darkness. Japanese aesthetics are frequently described as finding sentimentality in the hidden reverse side of things; it tends to cherish not the visible brilliance of a surface, but rather the unseen shadows behind it. Consequently, from even before the Heian era, few poets composed about the sun, whereas many chose the moon as their poetic theme in waka and haiku. Furthermore, these poets were most moved not by a full moon, but by the dimly illuminated shapes of crescent moons or new moons, often depicting not the moon itself but the faint reflections of moonlight on ponds or lakes.

This sensitivity reflects a perception that “beauty lies precisely in imperfection,” echoing the principles of yin-yang philosophy. Indeed, Ashikaga Yoshimasa (足利義政), the shogun who built Ginkaku-ji Temple (銀閣寺, 1490), is said to have done so to appreciate moonlight—particularly the subtle beauty of the slightly incomplete thirteenth-night moon rather than the brightness of a full moon. The aesthetic sensibility favoring partial illumination—beauty blended with shadows—has long been integral to the Japanese spirit. While Ginkaku-ji’s modest appearance was partially influenced by the declining finances of the Ashikaga shogunate, even the earlier Kinkaku-ji Temple (金閣寺, 1397) constructed by Yoshimasa’s predecessor, Ashikaga Yoshimitsu, notably combined gold leaf with a refined sense of tranquility and shadow, consciously avoiding excessive brilliance.

I intend to further discuss tea rooms in future articles, but understanding first that this “appreciation of shadow” permeates Japanese architecture, art, and philosophy can significantly enrich travel experiences in Japan. The quiet interplay of faint light and shadow through shoji doors in traditional rooms, the solemn presence within darkened shrine sanctuaries, and the ethereal statues softly illuminated by a single ray of temple light—all these offer profound emotional depth and lingering resonance unattainable through mere brightness. These examples strongly suggest a conviction deeply held in Japanese culture: true beauty emerges precisely from contrasts between yin and yang, light and darkness. While contemporary lifestyles increasingly reject darkness due to abundant artificial lighting, occasionally dimming the lights and immersing oneself in quiet shadow may allow one to sense the breathing traditions still pulsing within the Japanese aesthetic consciousness.

Wherever there is light, there is shadow—the beauty of shadows cultivated by Japanese culture quietly speaks to us of harmony and the profound value of subtle emotional experiences.
