Wise and Foolish Sutra Volume 15 (442 Lines)

Kengu-kyō, Volume 15 (442 lines): A National Treasure of Eighth-Century Buddhist Calligraphy at Tōdai-ji

Among the countless treasures held at Tōdai-ji in Nara, few are as revered by connoisseurs of classical calligraphy as the Kengu-kyō, Volume 15—a 442-line Buddhist sutra manuscript from the Nara period (8th century). Designated a National Treasure of Japan in 1951, this single scroll has long been celebrated as a masterwork of early Japanese brushwork. It belongs to a small, legendary group of related scrolls traditionally known as Ōjōmu (literally, "Great Shōmu"), a name derived from the ancient belief that the characters were personally brushed by Emperor Shōmu, the great eighth-century sovereign who built Tōdai-ji and its Great Buddha.

While modern scholars now consider the imperial attribution a later legend, the cultural aura surrounding these scrolls remains undimmed. For over a thousand years, even the smallest fragments of Ōjōmu have been treasured as the finest examples of Nara-period sutra writing, often pasted at the very opening page of noble collectors' calligraphy albums as emblems of prestige.

Historical Background

The Kengu-kyō, or Sutra of the Wise and the Foolish, is one of the great narrative sutras of East Asian Buddhism. Also known in Japanese as Kenguinnen-kyō (the Sutra of the Causes and Conditions of the Wise and the Foolish), it is a compilation of sixty-two chapters that illustrate Buddhist moral principles through vivid parables and stories of karmic cause and effect. Originating in Central Asia and translated into Chinese in the fifth century, the text was copied widely in early Japan, where its didactic tales resonated with newly ordained monks and pious lay patrons alike.

Volume 15 of the Tōdai-ji manuscript was produced during the Nara period (710–794), an era when the imperial court invested extraordinary resources into establishing state Buddhism. Emperor Shōmu (701–756) was the central figure of this effort: he commissioned the casting of the Great Buddha at Tōdai-ji, founded the system of provincial temples (kokubunji), and directed the state-run sutra copying bureau (shakyōjo) to produce vast numbers of scriptures.

This scroll is thought to have been kept originally at Tōdai-ji's Kaidan-in, the ordination hall where newly trained monks received the precepts. By the Kamakura and Muromachi periods, however, many companion scrolls had left the temple and been cut into small fragments for circulation among collectors. Volume 15, remarkably, survives with most of its text intact—a rarity that underpins its exceptional status today.

Why It Was Designated a National Treasure

The scroll was designated a National Treasure on June 9, 1951, under the postwar Law for the Protection of Cultural Properties. Its designation rests on several overlapping qualities that set it apart even among other Nara-period sutras.

First, the calligraphy itself is extraordinary. Most Nara-period sutras were written at roughly seventeen characters per line in a modest, standardized hand. The Ōjōmu scrolls, in contrast, use only twelve to thirteen large, generously spaced characters per line, each one brushed with dignified composure. The visual impact is monumental, and the expense of the format alone suggests a commission of the highest order.

Second, the writing surface is unusual. Rather than the standard yellow hemp paper (ōmashi) used in the state scriptorium, Ōjōmu was copied onto dabishi—a luxurious white paper made from the bark of the spindle tree (mayumi). The combination of smooth white paper and bold black characters produces a refined, almost sculptural quality.

Third, the scroll is unusually complete. Of the four National Treasure-designated Ōjōmu manuscripts held across Japan—at Tōdai-ji, the Maeda Ikutokukai, the Tokyo National Museum, and the Hakutsuru Museum—the Tōdai-ji Volume 15 preserves one of the largest continuous passages of text. Its survival as a single substantial scroll, rather than as scattered fragments, allows viewers to appreciate the original rhythm of the calligraphy across hundreds of lines.

Highlights and Points of Interest

Visitors who have the rare chance to see this scroll in person are often struck by the confident authority of its brushwork. The characters are written in a form of regular script (kaisho) that draws on Chinese Six Dynasties and early Tang traditions, yet already hints at the distinctive rhythm that would define classical Japanese calligraphy. Specialists believe the writer may have been either a Chinese-born scribe working in Nara or an exceptional master among the professional sutra copyists of the imperial scriptorium.

The stories recorded in the Kengu-kyō itself also reward attention. The sutra's parables include accounts of virtuous almsgiving, the consequences of pride and greed, and dramatic moments in the lives of the Buddha's disciples. Readers of classical Japanese and East Asian literature will recognize narrative motifs that later appeared in setsuwa collections such as the Konjaku Monogatari.

Because of the manuscript's fragility, the scroll is almost never placed on long-term display. When it is shown—typically at special exhibitions at the Nara National Museum or the Tokyo National Museum—it attracts calligraphy enthusiasts, historians, and Buddhist scholars from around the world.

Visitor Information

The Kengu-kyō scroll is preserved by Tōdai-ji and is not on regular public view. Visitors interested in seeing it should check announcements by major museums such as the Nara National Museum, which occasionally feature it in special exhibitions. Most recently, it was displayed at the Nara National Museum's "Super Kokuhō: The Radiance of Prayer" exhibition in 2025, and in "Jewels of Buddhist Art" in late 2022.

A visit to Tōdai-ji itself, however, is one of Japan's most moving cultural experiences and is open throughout the year. The temple complex includes the Great Buddha Hall (Daibutsuden), the world's largest wooden structure of its kind; the Hokkedō (Sangatsudō), the oldest surviving building on the precincts; and the Tōdaiji Museum, which rotates selected treasures from the temple's extensive collections. Even when the Kengu-kyō scroll itself is not on view, the museum offers an excellent introduction to the rich tradition of Nara Buddhist art.

Nearby Attractions

Tōdai-ji sits at the heart of Nara Park, surrounded by some of Japan's most important historic sites. Visitors can comfortably combine the temple with:

• Kasuga Taisha, the vermilion-lacquered shrine founded in the 8th century and famed for its lanterns
• Kōfuku-ji, home to a rebuilt five-story pagoda and a superb collection of Buddhist sculpture
• The Nara National Museum, Japan's leading institution for Buddhist art
• Shōsō-in (exterior viewing only), the imperial treasure house holding Emperor Shōmu's personal items
• Naramachi, the historic merchant district with preserved townhouses and local craft shops

The park's famous sika deer, considered sacred messengers of the kami, wander freely through the grounds and provide an experience unlike any other in Japan.
