Lotus Sutra (Kunoji-kyo): A Magnificent National Treasure of Decorated Sutras

Among the countless treasures of Japanese Buddhist art, few objects embody the aesthetic refinement of the Heian aristocracy as vividly as the Lotus Sutra known as the Kunoji-kyo. This extraordinary set of decorated sutra scrolls, created in the 12th century under the patronage of Emperor Toba and his consorts, represents one of the finest examples of the art of sutra embellishment ever produced in Japan. Designated as a National Treasure, this privately owned set of four scrolls offers visitors a rare glimpse into the spiritual devotion and artistic sophistication of Japan's imperial court nearly nine hundred years ago.

What Is the Kunoji-kyo?

The Kunoji-kyo is the collective name for a set of sumptuously decorated copies of the Lotus Sutra (Hokekyō) that were originally preserved at Kunoji Temple on Mount Kuno in Shizuoka Prefecture. The temple later became known as Tesshuji, and it is from its original name that these sutras derive their designation.

The complete set originally comprised 30 scrolls: the main text of the Lotus Sutra divided into 28 chapters, plus an opening sutra (Muryōgikyō) and a closing sutra (Kanfugenkyō). This format is known as a "kechien ipponkyō," or dedicatory one-chapter-per-person sutra, in which 30 individuals each took responsibility for transcribing one scroll as an act of religious merit. The names of these dedicators are inscribed at the end of each scroll, revealing that the project was centered around Emperor Toba (1103–1156), his empress Taikenmon'in (Fujiwara no Shōshi, 1101–1145), and his consort Bifukumon'in (Fujiwara no Tokushi, 1117–1160), along with other members of the imperial court.

The privately owned set designated as heritage ID 746 consists of four scrolls: the Yakusōyu-hon (Parable of Medicinal Herbs), Jūji-yujutsu-hon (Emerging from the Earth), Zuiki-kudoku-hon (The Benefits of Responding with Joy), and Fugen-bosatsu-kanhotsu-hon (The Encouragements of Bodhisattva Universal Worthy). These four scrolls were designated as a National Treasure on September 15, 2017, and are frequently displayed at the Nara National Museum.

Historical Background

The Kunoji-kyo was created around 1141 (Eiji 1), a pivotal year in which Emperor Toba took Buddhist vows and became a cloistered emperor. This event is believed to have been the occasion for the commissioning of these sutras, as the act of transcribing sacred texts was considered a powerful means of accumulating religious merit and ensuring rebirth in the Pure Land.

The late Heian period was an era of profound religious anxiety among the aristocracy. The concept of mappō—the belief that the world had entered a degenerate age in which the Buddha's teachings would decline—motivated the nobility to commission elaborate religious works as acts of devotion. The Kunoji-kyo reflects this spiritual climate, representing an extraordinary investment of artistic skill and precious materials in the service of Buddhist faith.

The sutras were initially deposited at Anrakujuin, Emperor Toba's temple in the southern outskirts of Kyoto. At some point they were transferred to Kunoji Temple in Suruga Province (modern-day Shizuoka). During the Sengoku period, the warlord Takeda Shingen seized Mount Kuno to build a fortress, forcing the temple to relocate to its present site in the Muramatsu area of Shimizu. Following a period of decline, the temple was revived in the Meiji era by the famous swordsman and calligrapher Yamaoka Tesshū, who renamed it Tesshuji.

Of the original 30 scrolls, 28 have been identified. Tesshuji retains 19 scrolls (designated as a separate National Treasure in 1952), the Tokyo National Museum holds 3 scrolls, the Gotoh Museum owns 2 scrolls, and 4 scrolls are in private hands—the very scrolls that constitute this National Treasure designation. The remaining 4 scrolls are currently unaccounted for.

Why It Was Designated a National Treasure

The Kunoji-kyo holds an exceptional position in Japanese art history for several reasons. As a set, it is the oldest substantially complete group of decorated one-chapter-per-person sutras surviving in Japan. It predates even the famous Heike Nōkyō (Sutras Dedicated by the Taira Clan), which was created in 1164, making the Kunoji-kyo an invaluable record of the artistic techniques and aesthetic sensibilities of the mid-12th century court.

The four privately owned scrolls are particularly noteworthy for their superb state of preservation and the quality of their decoration. The paper (ryōshi) is adorned with scattered pieces of gold and silver cut leaf (kirikane), fine gold and silver dust (sunago), and thin strips of gold and silver foil (noge). The ruled lines (kaisen) that guide the calligraphy are drawn in silver ink. Some scrolls feature additional embellishments, including lotus flowers and arabesque patterns painted in gold and silver pigment along the upper and lower margins.

The frontispiece paintings (mikaeshi) of certain scrolls are decorated with Yamato-e style imagery depicting aristocratic figures and Buddhist scenes, executed with remarkable delicacy. These paintings provide invaluable evidence of court painting styles of the period. The calligraphy itself, written by various hands of the imperial circle, demonstrates the refined aesthetic of Heian-period handwriting at its most accomplished.

Artistic Highlights and What to Look For

When viewing the Kunoji-kyo, visitors should pay close attention to several key features that make these scrolls so extraordinary.

The decorated paper is perhaps the most immediately striking element. Each scroll uses specially prepared paper that has been dyed in subtle colors and then lavishly embellished with metallic materials. The overall effect creates a shimmering, jewel-like surface that catches the light in constantly shifting ways. The gold and silver elements are applied in various forms—tiny cut squares, fine dust, and thin strips—creating layers of texture and luminosity that photographs cannot fully capture.

The diversity among the scrolls is another fascinating aspect. Because each scroll was produced by a different dedicator, each one has its own distinctive character. Some are more elaborately decorated than others, and the calligraphic styles vary according to the individual writer. This variety within a unified set gives viewers a sense of the different personalities and aesthetic preferences that existed within the court circle.

The Kunoji-kyo is also counted among Japan's three greatest decorated sutras (sandai sōshokukyō), alongside the Heike Nōkyō at Itsukushima Shrine and the Fan-Shaped Sutra (Senmen Hokekyō Sasshi). Together, these three masterworks represent the pinnacle of the Japanese decorative sutra tradition, and seeing any one of them is an unforgettable experience for art lovers and history enthusiasts alike.

Where to See the Kunoji-kyo

The four privately owned scrolls designated as heritage ID 746 are frequently exhibited at the Nara National Museum, particularly during the winter exhibition series titled "Jewels of Buddhist Art" (Shugyoku no Bukkyō Bijutsu). Because these are delicate paper works, they are displayed on a rotating basis and are not available for viewing at all times. Visitors interested in seeing the Kunoji-kyo should check the museum's exhibition schedule in advance.

The Nara National Museum is located in the heart of Nara Park, surrounded by some of Japan's most celebrated cultural sites, including Todaiji Temple, Kofukuji Temple, and Kasuga Taisha Shrine. The museum is approximately a 15-minute walk east from Kintetsu Nara Station, or visitors can take the city loop bus to the "Himuro Jinja / Kokuritsu Hakubutsukan" stop.

In addition to the privately owned scrolls, the 19 scrolls held by Tesshuji are entrusted to the Tokyo National Museum, where they are regularly displayed in the National Treasure Gallery (Room 2) of the Honkan building. The Gotoh Museum in Tokyo's Setagaya Ward also occasionally exhibits its two scrolls.

Nearby Attractions

A visit to see the Kunoji-kyo at the Nara National Museum can easily be combined with exploration of the surrounding cultural treasures. Nara Park itself is home to the famous free-roaming deer, considered divine messengers of the nearby Kasuga Taisha Shrine. Todaiji Temple, with its enormous Great Buddha (Daibutsu), is just a short walk away, as is the beautiful five-storied pagoda of Kofukuji Temple.

The museum's own permanent collection is well worth exploring. The Nara Buddhist Sculpture Hall (Nara Butsuzōkan), housed in a distinguished Meiji-era Western-style building, displays over 100 Buddhist sculptures at all times, offering one of the finest surveys of Japanese Buddhist sculpture anywhere in the world.

For those interested in Japanese gardens, the nearby Isuien Garden and Yoshikien Garden provide tranquil settings for relaxation. The Naramachi district, the old merchant quarter south of the museum, offers charming streets lined with traditional townhouses, local craft shops, and restaurants serving Nara's distinctive cuisine.
