Yellow Emperor's Inner Classic, Volume 1

A Chinese Medical Text That Survived in Kyoto

Two paper scrolls kept at Ninna-ji, a temple in the northwest of Kyoto, hold the opening volume of a work that has nearly vanished in the country where it was written. The text is the Huangdi Neijing Mingtang (Kōtei Daikei Meidō in Japanese), the "Hall of Light" portion of the great Chinese medical canon ascribed to the legendary Yellow Emperor. China kept only fragments. Japan kept enough to read.

Designated a National Treasure in 1952, the two scrolls are registered together as Huangdi Neijing Mingtang, Volume One. They are not display pieces in the ordinary sense. The paper is thin, the ink faded in places, and the page is filled with dense columns of classical Chinese setting out where on the body a physician should place a needle.

The Text and the Man Who Compiled It

The Huangdi Neijing, or Inner Canon of the Yellow Emperor, is the foundation of Chinese medicine. It takes the form of a dialogue: the Yellow Emperor questions his ministers about the body, about illness, and about the forces that move through both. Two of its parts, the Suwen on theory and the Lingshu on acupuncture, are still studied today.

In the seventh century a Tang-dynasty scholar named Yang Shangshan reorganized and annotated this material into two further works. One was the Taisu ("Grand Basis"), which gathers the theoretical chapters. The other was the Mingtang ("Hall of Light"), concerned with the practical side of treatment: the location of acupuncture points and the rules for needling them. The Ninna-ji scrolls are the Mingtang.

Yang's versions were never produced in large numbers. Within a few centuries both the Taisu and the Mingtang had dropped out of circulation in China and were effectively lost there. What saved them was distance. Copies had been carried to Japan, where court physicians treated such texts as professional inheritance and recopied them by hand across generations.

Why the Scrolls Matter

The value of the Ninna-ji Mingtang is partly a question of arithmetic. It is one of the very few surviving witnesses to a text that scholars elsewhere can reconstruct only in pieces. For a historian of medicine, a single legible volume of Yang Shangshan's commentary outweighs a shelf of later printings.

The National Treasure designation, granted on 22 November 1952, places the Mingtang alongside the temple's twenty-three-scroll Taisu under one registration number. The cultural-property record classes both as shoseki tenseki, written works and classical texts, the category reserved for manuscripts whose importance rests on their content and their age rather than on any decoration.

There is a second reason the scrolls are prized. Because they were copied with care by people who could read what they were copying, they carry not only Yang's main text but his interlinear notes. That layering lets researchers separate the original wording from later additions, a distinction that printed Chinese editions had blurred.

Two Scrolls, Two Centuries Apart

The designation counts two scrolls, and they were not made at the same time. One was written in 1296, during the Kamakura period. The other is a later copy of the first, produced in 1383, in the Nanboku-chō era. A scribe of the fourteenth century sat with the older scroll open beside him and reproduced it line by line, preface and all.

This is worth pausing over. The two scrolls hold the same first volume of the Mingtang, so their texts agree. What differs is the hand and the paper, and the gap of nearly ninety years between them records a habit that kept Chinese medicine alive in Japan: when a manuscript grew fragile, you copied it again before it failed.

The cultural-property listing assigns the whole group to the Heian period, a dating that suits the older Taisu scrolls rather than the Mingtang. The Mingtang's own colophons give the firmer years of 1296 and 1383.

Seeing the Scrolls, and Ninna-ji Itself

A visitor should set expectations honestly. The Mingtang scrolls are not on permanent view. Ninna-ji keeps its manuscripts in the Reihōkan, a treasure house built in 1927 that opens to the public only in spring and autumn, roughly April to May and October to November. Even then the displays rotate, and a given exhibition may show other works from the temple's medical collection instead.

The spring opening coincides with the famous Omuro cherries, a low-growing variety that blooms later than most Kyoto sakura. The autumn opening falls during the foliage season. Either window is the time to ask at the temple whether the scrolls, or their companion Taisu and the Ishinpō, are among the items currently on show.

Ninna-ji rewards the trip regardless. The temple was founded in 888 by Emperor Uda, who later took holy orders and lived here, which is why it carries the name Omuro Gosho, the Omuro palace. Its Kondō, or main hall, is itself a National Treasure: a former ceremonial building moved from the Kyoto Imperial Palace in the seventeenth century, and the oldest surviving structure of its kind.

Around the Temple

The grounds repay slow walking. A five-story pagoda from 1644 stands near the center, unusual for the way its roofs barely taper toward the top. The Niōmon gate at the entrance, built in the same decade, keeps an older court style that suits a temple founded by an emperor.

Ninna-ji sits in a quieter corner of Kyoto than the temples of the eastern hills, and it pairs naturally with nearby sights. Ryōan-ji, with its celebrated rock garden, is a short walk to the east, and Kinkaku-ji, the Golden Pavilion, lies not much farther. The three can be linked into one unhurried day across the city's northwest side.
