Genron Jōmyō

A Manuscript That Records the Day It Was Finished

Most texts surviving from Japan's seventh and eighth centuries reach us without a date. The Jōmyō Genron is different. At the close of its fourth and sixth scrolls, the copyist left a short note recording when he set down his brush: the twelfth month of the third year of the Keiun era, a reckoning that corresponds to the year 706. That single line of writing is the reason these eight scrolls hold the rank of National Treasure.

The text itself is a work of Buddhist scholarship from China. Its author, Jizang (549–623), honored with the title Master Jiaxiang, was the monk who brought order to the teachings of the Sanron school, the East Asian form of Madhyamaka philosophy organized around the idea of emptiness. The Jōmyō Genron is his extended study of the Vimalakīrti Sutra, one of the most admired scriptures in the Mahāyāna tradition. The title borrows the Chinese name for the scripture's hero: Jōmyō, "Pure Name," renders the Sanskrit Vimalakīrti.

That hero is an unusual one. Vimalakīrti is no monk but a wealthy layman of the city of Vaishali, and across the sutra he outmatches the Buddha's own disciples and bodhisattvas in debate. The story reaches its height when the assembly takes up the question of how to enter the gate of non-duality, the recognition that opposites such as purity and defilement, or life and death, are not finally separate. Each speaker answers in words. Asked last, Vimalakīrti says nothing at all, and his silence is praised as the truest answer of them all. Jizang's commentary works patiently through the meaning behind episodes like this one.

Why It Was Designated a National Treasure

The worth of these scrolls rests less on the words of the text than on the act of copying them. Manuscripts that can be dated with confidence to the years around 700 are very few. Japan's oldest dated sutra copy, the Kongōjō Daranikyō of 686, is kept at the Nara National Museum; the Jōmyō Genron, finished twenty years later, stands close behind it as one of the rare surviving manuscripts of the period whose date can be read straight off the page. For a historian, a fixed date turns a beautiful object into a measuring stick against which undated works can be judged.

The brushwork carries its own importance. The characters are written in the firm, slightly angular manner associated with the Six Dynasties period of China, a style already old-fashioned by 706 and preserved here in a way that later Japanese calligraphy seldom matched. Each line holds between twenty-nine and thirty-five characters, ruled out in advance with faint ink guidelines on paper made from hemp fiber.

A third layer of value is easy to overlook. Readers of later centuries added small marks and glosses, called kunten, to help themselves read the dense classical Chinese in Japanese word order. Those marks make the scrolls a primary source for scholars tracing how the Japanese language was read and pronounced in the early medieval period.

Looking Closely at the Scrolls

The set is not uniform, and that is part of its interest. Five of the eight scrolls, including the two that carry the 706 colophons, belong to the original copying. Over the centuries some scrolls were lost and replaced: the first was rewritten in the early Heian period, and the second and fifth in the Kamakura period. Unrolled side by side, they show several hands separated by four or five hundred years, each generation mending what time had worn away.

The fourth scroll, the one dated to the fifth day of the twelfth month, runs almost six meters in length and stands about twenty-eight centimeters tall. Seen in person, the contrast between the early brushwork and the later supplements rewards a slow look. The older sections feel deliberate and archaic; the supplements follow the conventions of their own times.

Seeing It at the Kyoto National Museum

The Jōmyō Genron belongs to the Kyoto National Museum, in the Higashiyama district on the eastern side of the city. Like most early manuscripts, it is sensitive to light and is shown only on occasion, often within special exhibitions devoted to ancient calligraphy and sutra copying. Anyone hoping to see it should check the museum's current exhibition schedule before visiting rather than expecting it on permanent view.

The museum sits within easy reach of some of Kyoto's best-known sights. Directly across the street stands Sanjūsangen-dō, the long wooden hall famous for its array of more than a thousand statues of Kannon. The slopes climbing toward Kiyomizu-dera, lined with pottery shops and tea houses, begin a short walk to the north, and the temple districts of southern Higashiyama can fill an easy day around a museum visit.
