Song Dynasty Version of Liu Mengdu Collection

Song Edition of Liu Mengde's Collected Works: A Tang Poet's Voice Preserved Across Eight Centuries

Deep within the rare-book stacks of the Tenri University Library in Nara rests a set of twelve modest-looking volumes whose significance reaches far beyond their unassuming appearance. The Song Edition of Liu Mengde's Collected Works (Sōhan Ryūbōtoku Bunshū) is a National Treasure of Japan—a printed anthology of the poems and prose of the Tang-dynasty poet Liu Yuxi, produced in twelfth-century China and carried across the sea by one of Japan's most celebrated Zen pioneers. For visitors who love classical literature, East Asian cultural history, or simply the quiet romance of old books, this is one of the most evocative treasures in the country.

Historical Background: The Poet Behind the Book

The poet whose works fill these twelve volumes was Liu Yuxi (772–842), a major literary figure of the middle Tang dynasty. His courtesy name was Mengde—meaning "dream-fulfilled"—and because educated readers in premodern East Asia often referred to writers by their courtesy names rather than their given names, the collection has been known for centuries as Liu Mengde's Collected Works rather than Liu Yuxi's.

Liu Yuxi lived through one of the most turbulent eras of Chinese intellectual history. A friend and exact contemporary of the famous poet Bai Juyi (Haku Rakuten in Japanese), he was celebrated for clear, musical verse that drew on folk song traditions. His cycles of Bamboo Branch Songs and Willow Branch Songs, as well as elegiac pieces such as Black Robe Lane and Stone City, have been studied and admired continuously for over a thousand years. Bai Juyi affectionately called him the "hero of poetry," openly admitting that Liu was the one rival whose verse he could never quite surpass.

Despite his literary brilliance, Liu's political life was turbulent. He was repeatedly exiled over a span of some twenty-three years for his involvement in reform movements, yet he continued writing throughout, producing some of his most lyrical work during these periods of rural banishment. The collection preserved at Tenri transmits this entire body of poems and essays as it was known in China during the Song dynasty.

Why It Was Designated a National Treasure

The Japanese government designated this book a National Treasure on June 22, 1955, placing it among the highest-ranked cultural properties in the country. Several factors combine to give it this exceptional standing.

The volumes are Song-dynasty printed books—products of the golden age of East Asian woodblock printing. The Song period (960–1279) saw a dramatic flowering of printing technology in China, with Sichuan, Fujian, and the Zhejiang region becoming famous centres of publication. Books produced in this era are treasured worldwide for the clarity of their carving, the quality of their paper, and the aesthetic refinement of their page layouts. The Tenri volumes are believed to have been printed in the early Southern Song, around the Shaoxing era (1131–1162), making them roughly contemporary with Japan's late Heian to early Kamakura period.

Second, the book's transmission history links two of the great threads of medieval East Asian culture. According to tradition, the volumes were brought to Japan by the monk Eisai (1141–1215), founder of the Rinzai school of Zen in Japan and founding abbot of the temples Shōfuku-ji in Hakata, Jufuku-ji in Kamakura, and Kennin-ji in Kyoto. Eisai made two voyages to Song China and is equally famous for introducing the custom of tea drinking to Japan. After his return, the book was preserved at Kennin-ji, the great Rinzai monastery he founded in 1202.

Third, the volumes bear the impression of a seal reading "Tenzan", which is understood to mark the ownership or personal inspection of the third Ashikaga shogun, Ashikaga Yoshimitsu (1358–1408). Yoshimitsu was a passionate collector of Chinese artefacts, and objects bearing his seals form part of the celebrated group of shogunal treasures known as the Higashiyama Gyomotsu. Few surviving printed books in the world can claim a chain of custody that runs directly from a pioneering Zen master to one of medieval Japan's most powerful cultural patrons.

Highlights of the Collection

A Witness to Song Printing

For bibliophiles, the book itself is a revelation. Song editions are celebrated for their disciplined character shapes, generous margins, and the quiet beauty of their mulberry-fibre paper. Holding a Song imprint in the hand—even through protective glass at an exhibition—is often described as experiencing the foundation of East Asian book design in its purest form.

A Bridge Between Zen and Chinese Literature

The book embodies a fascinating moment when Chinese literary culture and Japanese Zen practice grew intertwined. Monks like Eisai did not travel to Song China only for religious training; they returned with books, ideas, tea, and aesthetics that would reshape Japanese society. A collection of Tang poetry carried home by a Zen master is not an incidental curiosity—it reflects the very texture of intellectual exchange in the period.

A Touch of Medieval Japanese History

The presence of the Tenzan seal turns the book into a silent witness to Ashikaga-era culture. Yoshimitsu, builder of Kyoto's Golden Pavilion (Kinkaku-ji), gathered Chinese paintings, ceramics, and books as part of a refined aesthetic programme that defined East Asian cultural ideals in Japan for centuries afterward.

Visitor Information

The volumes are preserved in the rare-book stockroom of the Tenri University Library and are not on permanent display. However, the library and its affiliated institutions organise regular exhibitions in which selections from the collection—sometimes including this work—are shown to the public. Two venues in particular are worth watching:

• The Tenri University Library in Tenri City, Nara, which holds annual exhibitions and opens to the general public aged fifteen and over.
• The Tenri Sankokan Museum, located nearby on the same campus, which occasionally features library treasures in its special exhibitions.
• The Tenri Gallery in Tokyo (Kanda), a satellite exhibition space that also stages shows drawing on the collection.

Before travelling, please check the library's official website or contact the institution directly to confirm whether this specific volume is on view during your planned visit. Exhibitions of rare books are often rotated on a short schedule to protect the materials from light damage.

The library building itself is a pleasure to see. Opened in 1930 and recognised as a Registered Tangible Cultural Property, its Romanesque-style stone façade and its interior woven around a central stack tower make it one of the most architecturally distinctive academic libraries in Japan.

Surrounding Attractions

Tenri is a quietly rewarding destination that rewards an unhurried day of walking. Close to the library you will find:

• Tenri Sankokan Museum — an ethnographic and archaeological museum with wide-ranging collections from across Asia, the Pacific, and the Americas.
• Isonokami Jingū Shrine — one of the oldest Shinto shrines in Japan, mentioned in the eighth-century Nihon Shoki, set in a forest about twenty minutes' walk north of the library.
• Yamanobe-no-michi — "the path along the mountains," Japan's oldest recorded road, winding past ancient tombs, shrines, and rice terraces between Tenri and Sakurai.
• Tenri Honmichi shopping arcade — an atmospheric covered shopping street running from Tenri Station toward the Tenrikyō headquarters, lively with inexpensive eateries and traditional shops.

The nearby ancient capitals of Nara and Asuka are each within an easy train ride, making Tenri a natural overnight stop for travellers exploring the cultural landscape of Yamato.
