A Surviving Fragment of the Poet Who Shaped Japanese Letters
Few foreign books mattered to Japan as much as the collected works of Bai Juyi. The Tang poet, who lived from 772 to 846, wrote in a deliberately plain and accessible style, and his anthology, the Hakushi Monjū, reached Japan within his own century. Heian aristocrats read it, quoted it, and built their own Chinese-verse composition on it; its lines echo through The Tale of Genji and The Pillow Book. To know this collection was, for centuries, part of what it meant to be educated in Japan.
The Sanbō-in on Mount Kōya holds a single scroll that preserves part of the third volume of that work, a Kamakura-period manuscript copy known as the Hakushi Monjū Maki Daisan Zankan, the "fragmentary scroll of volume three." The word zankan, fragmentary scroll, is exact: what survives is a portion, not the whole, but even a portion of so foundational a text carries weight.
Sanbō-in is a sub-temple of Kōyasan, founded by tradition by Tamayori-gozen, said to be the mother of Kūkai. It is one of the mountain's lodging temples, and over its long history it has gathered a notable group of books and images, including a Nara-period National Treasure scripture, alongside this medieval copy of a Chinese literary classic.
Why It Is an Important Cultural Property
The scroll was designated an Important Cultural Property on 30 May 1949. Its value is textual and historical. The works of Bai Juyi circulated in Japan through hand-copied manuscripts, and the earliest of these copies are now of the first importance for scholars trying to establish what the poet actually wrote, since they can preserve readings older than later printed editions. A Kamakura-period copy of a single volume, even fragmentary, is a witness in that long chain of transmission.
It also speaks to where learning was kept. Mount Kōya was not only a centre of religious practice but a repository of texts, and a temple library that held both Buddhist scripture and the secular verse of a Chinese poet reflects how broadly medieval monastic culture read. The survival of this scroll at Sanbō-in places a major work of Tang literature inside the scholarly life of the mountain.
For a work of calligraphy and copying, condition and authenticity matter more than spectacle. What is designated is precisely this: an old manuscript fragment of a canonical text, valued for what it transmits rather than for any single dramatic feature.
What to Look For
The scroll is held by a working sub-temple and is not on regular public display, so an appreciation of it begins with understanding rather than viewing. The thing to grasp is the act of copying itself. Before printing was common, a text like Bai Juyi's survived only because successive readers wrote it out by hand, character by character, volume by volume. Each copy was both a study aid and an offering of effort, and each introduced or preserved small variations that later scholars can read like fingerprints.
Consider, too, the cultural geography. A poem composed in ninth-century China, in a style its author hoped even an ordinary reader could follow, was carried across the sea, absorbed into the literary bloodstream of the Heian court, and then copied again in the Kamakura period by hands on a Buddhist mountain in the Kii peninsula. The fragment at Sanbō-in is one physical link in that improbable journey.
Visitors to Mount Kōya who wish to see medieval calligraphy and manuscripts at first hand are best served by the Reihōkan museum, which displays a rotating selection of the mountain's designated texts and may show comparable scrolls. Sanbō-in itself is known as a temple lodging set among gardens, and a stay there places you within the same scholarly community that has kept this scroll for centuries.

Q&A
- What is the Hakushi Monjū?
- It is the collected literary works of the Tang poet Bai Juyi (772-846). Hugely influential in Japan from the Heian period onward, it shaped both Chinese-verse composition and classical Japanese literature.
- What does "fragmentary scroll" mean here?
- It means only part of the third volume survives, rather than the complete text. Even so, an early manuscript fragment of so important a work has real scholarly value.
- Why does a manuscript copy matter so much?
- Before printing was widespread, texts survived through hand-copying. Old copies can preserve readings closer to the original than later editions, making them key evidence for how the work was transmitted.
- Can I see the scroll?
- It is held by Sanbō-in and is not on regular display. For medieval calligraphy and texts on Mount Kōya, the Reihōkan museum shows a rotating selection and is the better destination.
