Lotus Sutra (Volumes 2–7): A Sacred Manuscript Commissioned by the Legendary Sculptor Unkei

Hidden within the treasure vaults of Shinshō Gokurakuji—known affectionately as Shin-nyo-dō—in Kyoto's leafy Sakyō ward lies one of Japan's most remarkable National Treasures: six handscroll volumes of the Lotus Sutra, dating from 1183. What makes these scrolls extraordinary is not only their spiritual content but the story behind their creation. They were commissioned by Unkei, widely regarded as the greatest Buddhist sculptor in Japanese history, as a deeply personal act of devotion during one of the most turbulent periods in the nation's past.

What Is the Lotus Sutra?

The Lotus Sutra (Myōhō Renge Kyō) is one of the most influential and revered texts in Mahayana Buddhism. Originally composed in Sanskrit, the sutra was translated into Chinese by the monk Kumārajīva around 406 CE, and this Chinese version became the standard text used throughout East Asia. The scripture teaches that all sentient beings possess the potential to attain Buddhahood—a revolutionary concept that opened the path to enlightenment for everyone, regardless of status or background.

The complete Lotus Sutra comprises eight volumes (kan) containing 28 chapters (hon). Among the most celebrated chapters are the Hōben-bon (Chapter of Expedient Means), which proclaims the universal possibility of Buddhahood, and the Nyorai Juryō-bon (Chapter on the Lifespan of the Tathāgata), which reveals that the Buddha's lifespan is essentially infinite. In Japan, the Lotus Sutra has been a cornerstone of Buddhist thought since the time of Prince Shōtoku in the early seventh century and forms the doctrinal foundation of the Tendai and Nichiren schools.

The Story Behind the National Treasure

The six scrolls preserved at Shin-nyo-dō are Volumes 2 through 7 of an originally complete eight-volume set. Volume 1 has been lost over the centuries, and Volume 8 is held in a private collection. These scrolls are collectively known as the "Unkei Gankyō" (Unkei's Votive Sutra), after the master sculptor who initiated their creation.

According to the colophon inscribed on Volume 8, Unkei first conceived the idea of commissioning this sutra copying project during the An'gen era (1175–1177), when he was still in his twenties. Several years later, in the second year of the Juei era (1183), a woman known as Akomaru—believed by many scholars to have been Unkei's wife—provided the financial support that allowed the project to proceed. The actual calligraphy was executed by a monk named Chinga.

What makes these scrolls especially poignant is the context of their creation. In 1180, during the Genpei War between the Taira and Minamoto clans, the warrior Taira no Shigehira attacked the great temples of Nara in what became known as the Burning of the Southern Capital. Both Tōdai-ji and Kōfuku-ji were devastated by fire. Unkei, who had deep ties to these temples, used charred timber salvaged from the burned Great Buddha Hall of Tōdai-ji as the wooden dowels (jiku) around which the scrolls are wound—transforming remnants of destruction into instruments of prayer and renewal.

The ink used for copying the sutra text was made with sacred water drawn from Mount Hiei (the headquarters of the Tendai school), Kiyomizu-dera, and Mii-dera—three of the most spiritually significant sites in the Kyoto-Shiga region. The colophon further records that during the copying process, participants performed fifty thousand prostrations and chanted the title of the Lotus Sutra and the nenbutsu (invocation of Amida Buddha) one hundred thousand times each.

Why Was It Designated a National Treasure?

This set of Lotus Sutra scrolls was designated a National Treasure (Kokuhō) by the Japanese government, classified under the category of Calligraphy and Books (Shoseki Tenseki). The designation recognizes the scrolls' extraordinary value on multiple fronts.

First, the scrolls serve as an invaluable historical document related to Unkei, the most celebrated sculptor in Japanese art history. The colophon names 48 individuals who participated in the project, including the renowned sculptor Kaikei and other members of the Kei school. This provides scholars with a rare and detailed record of Unkei's personal circle and the collaborative nature of the Kei school workshop.

Second, the use of salvaged Tōdai-ji timber and sacred water from three major temple complexes speaks to the spiritual earnestness of the project and provides direct physical evidence linking the scrolls to the devastating events of 1180. Third, the scrolls represent a masterful example of late Heian-period sutra calligraphy and manuscript craftsmanship, preserving the religious practices and aesthetic sensibilities of the era.

Highlights and Points of Interest at Shin-nyo-dō

While the Lotus Sutra scrolls themselves are currently deposited at the Kyoto National Museum and are not regularly on public display, a visit to Shin-nyo-dō offers visitors the chance to experience the temple that has safeguarded these treasures for centuries. The temple's spacious and tranquil grounds provide a wonderful setting for appreciating Kyoto's layered history.

Unkei: The Master Sculptor Behind the Sutra

Unkei (c. 1150–1223) is widely considered the greatest Buddhist sculptor in Japanese history. A leading figure of the Kei school, he revolutionized Japanese sculpture by introducing an unprecedented degree of realism and emotional expressiveness. His most famous works include the colossal Niō guardian statues at the Great South Gate of Tōdai-ji in Nara (created in collaboration with Kaikei in just 72 days in 1203), the majestic Miroku Butsu and the lifelike portraits of the Indian philosophers Muchaku (Asanga) and Seshin (Vasubandhu) at Kōfuku-ji, and his earliest documented work, the seated Dainichi Nyorai at Enjō-ji (1176)—all designated National Treasures.

The Lotus Sutra scrolls at Shin-nyo-dō reveal a lesser-known but deeply personal side of Unkei: his profound Buddhist faith. The project demonstrates that for Unkei, creating sacred art was not merely a profession but a devotional practice integral to his spiritual life.
