Sanjūrokunin Kashū: The Oldest Illuminated Poetry Anthology in Japan

Tucked within the vast treasure house of Nishi Hongan-ji temple in Kyoto lies one of the most breathtaking manuscripts ever produced in Japan — the Sanjūrokunin Kashū, or Collection of the Thirty-Six Poets. Designated as a National Treasure, this early 12th-century anthology brings together the works of the Thirty-Six Immortals of Poetry, a celebrated canon of Japanese poets selected by the Heian-era courtier and literary critic Fujiwara no Kintō. What makes this manuscript truly extraordinary is not only the poetry it preserves but the sheer magnificence of its physical form: pages adorned with gold and silver leaf, torn-paper collage techniques considered the oldest of their kind in the world, and calligraphy penned by approximately twenty of the finest scribes of the late Heian court.

What Is the Sanjūrokunin Kashū?

The Sanjūrokunin Kashū is a compilation of waka poetry — Japan's classical thirty-one-syllable verse form — from thirty-six master poets spanning the Asuka, Nara, and Heian periods (roughly the 7th through 11th centuries). The canon of the Thirty-Six Immortals of Poetry was established by Fujiwara no Kintō around 1010 CE, and the concept of gathering their private anthologies (kashū) into a single collection emerged soon afterward. Among the several surviving manuscript copies, the one held at Nishi Hongan-ji is widely recognized as the oldest and most nearly complete, dating to around 1112 CE.

The collection originally comprised 39 volumes in the tetchōsō (butterfly binding) format, each approximately 20 cm tall and 16 cm wide. Of these, 32 volumes (containing 34 booklets) are believed to be original Heian-period works, while the remaining seven were added in later centuries to replace lost volumes. Three poets — Kakinomoto no Hitomaro, Ki no Tsurayuki, and Ōnakatomi no Yoshinobu — were allotted two volumes each, with the rest receiving one apiece. In total, the collection preserves over 6,400 poems, making it an indispensable resource for the study of classical Japanese literature.

Why Was It Designated a National Treasure?

The Sanjūrokunin Kashū was designated a National Treasure in 1951 for several compelling reasons that span the fields of literature, calligraphy, fine art, and decorative craft.

First, as the oldest surviving near-complete manuscript of the Thirty-Six Poets' anthology, it is an irreplaceable primary source for Japan's literary heritage, preserving the waka tradition from its golden age. Second, the calligraphy itself is of exceptional quality: the brushwork of around twenty scribes offers a panoramic view of aristocratic writing styles in the late Heian period. Among the identified calligraphers are Fujiwara no Sadazane, his son Fujiwara no Sadanobu, and the imperial consort Fujiwara no Michiko (known as the Jōkyōden no Nyōgo), each contributing their distinctive hand to the collection.

Third — and perhaps most remarkably — the manuscript's decorated papers (ryōshi) employ virtually every decorative technique known to the period. Cut-paper piecing (kiritsūgi), torn-paper collage (yaburitsugi), layered paper overlay (kasanetsugi), gold and silver leaf application, mica-stamped patterns, ink marbling (suminagashi), and painted underdrawings of landscapes, birds, and flowers all appear across the volumes. The torn-paper collage technique in particular has been recognized as the world's oldest known example of artistic collage, predating European experiments by many centuries. This fusion of poetry, calligraphy, and decorative arts into a single unified masterpiece is unparalleled in the history of Japanese cultural production.

The Splendor of the Decorated Papers

Each volume of the Sanjūrokunin Kashū presents a distinct visual world. The covers are fashioned from indigo or green silk gauze (ra), with silver-painted landscape scenes decorating the surface. Inside, the papers range from understated elegance — karakami sheets with mica-printed floral patterns, or thick tori-no-ko (literally "bird's egg") paper tinted in soft hues — to breathtaking extravagance. In the most elaborate volumes, irregularly torn sheets of different colors are pieced together in free-form compositions, then showered with gold and silver dust (sunago), cut foil (kirikane), and delicate painted motifs of flowers, grasses, birds, and streams.

Scholars have categorized the papers into five main types, reflecting the diversity of techniques employed. Particularly notable are the papers decorated with large-scale painted underdrawings (shita-e), which transform each page into a miniature painting over which the calligraphy dances. The effect is one of poetry and visual art merging seamlessly — a hallmark of Heian aristocratic aesthetics that prizes the harmony of word, image, and material beauty.

A Turbulent History: From Imperial Court to Nishi Hongan-ji

The manuscript is believed to have been produced around 1112 as a gift for the celebration of Retired Emperor Shirakawa's sixtieth birthday. It was likely commissioned by the imperial consort Fujiwara no Michiko, who is also thought to have contributed some of the calligraphy. After its creation, the collection was kept in the treasure house of Rengeō-in (Sanjūsangen-dō) in Kyoto.

In 1549, Emperor Go-Nara bestowed the anthology upon Shōnyo, the tenth head priest of Hongan-ji temple, which was then located at Ishiyama in present-day Osaka. This imperial gift is documented both in Shōnyo's diary (Tenbun Nikki) and in a letter from the emperor that survives today as an associated National Treasure designation.

Over the centuries that followed, the collection's existence was gradually forgotten within the temple. It was not until 1896 that the calligraphy scholar and poet Ōguchi Shūgyo, while conducting an investigation of old documents at the temple, rediscovered the manuscripts in the storehouse — causing a sensation in the academic world.

In 1929, the volumes containing the Ise Collection and the lower volume of the Tsurayuki Collection were disassembled and sold as individual leaves to fund the establishment of what is now Musashino University. These fragments, known as Ishiyama-gire (named after Hongan-ji's former location at Ishiyama), are now treasured individually in museums and private collections across Japan, including the Tokyo National Museum, the Nezu Museum, and the MOA Museum of Art.

Highlights and Must-See Aspects

While the Sanjūrokunin Kashū is not on permanent public display — as is common with fragile National Treasure manuscripts — select volumes are occasionally exhibited at special exhibitions organized by Nishi Hongan-ji or at major museums. When exhibited, visitors have the rare opportunity to see Heian-period calligraphy and decorative paper arts preserved in extraordinary condition. Key aspects to appreciate include the flowing elegance of the kana script, the ingenious paper collage compositions, the shimmer of gold and silver foil against dyed papers, and the subtle painted underdrawings that bring natural scenes to life beneath the poetry.

For those unable to view the originals, the Ishiyama-gire fragments are more frequently displayed at museums such as the Tokyo National Museum and the Kyoto National Museum. These individual leaves, remounted as hanging scrolls, allow visitors to examine the decorated papers and calligraphy at close range. High-quality facsimile reproductions are also available at the Ryūkoku Museum adjacent to Nishi Hongan-ji.

Visiting Nishi Hongan-ji Temple

Nishi Hongan-ji (formally Ryūkokuzan Hongan-ji) is the head temple of the Jōdo Shinshū Honganji-ha denomination of Pure Land Buddhism and a UNESCO World Heritage Site as part of the "Historic Monuments of Ancient Kyoto." Located in Kyoto's Shimogyo Ward, the temple complex features multiple National Treasure structures, including the grand Goei-dō (Founder's Hall), the Amida-dō (Amida Hall), the spectacular Hiunkaku pavilion — counted among Kyoto's three great pavilions alongside Kinkaku and Ginkaku — and the elaborately carved Karamon gate. The grounds are open to visitors free of charge, and morning services (shinjō gongyō) are held daily from 6:00 AM in the main halls.

Nishi Hongan-ji is conveniently accessible from JR Kyoto Station, approximately 15 minutes on foot or a quick 5-minute bus ride (routes 9, 28, or 75 to the "Nishi Honganji-mae" stop). Alternatively, JR Umekōji-Kyoto-Nishi Station on the San'in Line is about 10 minutes' walk away. The temple's proximity to Kyoto Station makes it an ideal starting point or concluding stop for a day of sightseeing in the city.
